Coal-mining accident statistics have been treated in a separate report 1 ; in the present Report statistics of railway accidents are considered. Special interest has always been shown in the risks connected with railway transport. On the one hand, the movement of trains contains particular dangers ; on the other hand, not only the workers b u t also passengers and the community are exposed to railway risks. These facts have led in most countries to the compilation of special railway accident statistics, in addition to statistics of compensation of industrial accidents. The present Report is confined to the industrial risks of railway employees only. Differences in the methods employed in compiling the statistics of railway accidents hamper comparisons of accident risk in different countries. I t is the task of this Report to analyse these differences and to enquire by what means and in which directions comparability may be attained, since at present incomparability is so great as to render any international comparison almost futile. As with coal-mining accident statistics, the main sources of incomparability appear to be variations in the methods of defining reportable accidents and casualties, of demarcating industrial railway risk, of calculating exposure, and of classifying the classes by causes. These points are therefore specially considered in this Report. 1 INTERNATIONAL LABOUR, OFFICE : Methods of Compiling Statistics of Coal-Mining Accidents. Studies and Reports, Series N (Statistics), No. 14. Geneva, 1929. 90 pp. CHAPTER I DEMARCATION OF RAILWAY RISK The notion "railway transport" usually implies the transport of goods and persons by rail on a road or track specially reserved for this purpose. Railway transport may be taken therefore not to include tramways. There are, however, doubtful cases, in which the railroad is combined with a general road which serves also for the regular transport of goods and persons between different places by trains, i.e. by a number of connected carriages driven by an engine or motor. The risks connected with the running of such street-trains will differ more or less from the risks of railways strictly speaking, since in order to reduce the risk involved in running the train on a public road the speed has to be reduced. The speed, as well as the intensitj', of the traffic will be, on the other hand, considerably influenced by the character of the permanent way. Narrow-gauge railways will not as a rule bear as dense and intensive a traffic as standard-gauge railways. Where narrow-gauge railways are included in the statistics, therefore, the risk should bo separately assessed for standard-gauge and narrow-gauge railways. A second important technical factor which may have an influence on risk is the mode of traction. It is evident t h a t electric traction entails certain risks which do not exist in the case of steam traction and vice versa. Some countries — for instance, the United States of America — publish accident statistics separately for electric and steam railways, but very summarily only for the former. Other countries have hitherto confined their statistics to steam railways, in view of the small significance of the electric railways. .In Switzerland, both are given together, also in Great Britain. I t would seem advisable to give certain kinds of accidents separately for steam and electric traction. Accidents on cog and rope railways should be separately recorded. — 4 — T H E STATISTICAL U N I T S The risk of railway transport derives its special nature from the movement of the trains. On the one hand, disturbances in the regular operation of the railway, due for instance to defects in the permanent way and in the rolling stock, or to negligence and mistakes on the part of the persons engaged in working the railway, are likely to have particularly serious consequences owing to the rapid movement and weight of the trains; on the other hand, other strictly personal events occurring during the regular operation of the railway, e.g. falling off a train in motion, may have serious results on account of the movement of the trains. The movement factor therefore enhances the dangers connected with failures or unforeseen events interfering with the regular operation of the railway, and consequently gives special importance to such events. The reporting of disturbances in the operation of railways, whether they have resulted in injury to persons or not, has therefore been considered desirable in many countries which compile special statistics of railway risk. In these statistics interest has largely centred on this so-called "accident", t h a t is, the event which has, or might have, caused injury to life, or which has caused damage (as distinct from the casualty, which refers to the personal case of injury). While the casualty — t h a t is, the fact of one person being injured by unexpected circumstances — is naturally the only unit on which compensation statistics are based, the safety and prevention points of view have led to the distinction in the special statistics of the two units : accident and casualty. The essential feature of risk is evidently the unexpected, unforeseen, and unpremeditated event. Considering the cases of injury, the qualification "unexpected" refers to the person injured : the event which resulted in injury was unforeseen by the person injured. The case is different, however, if events arejdistinguished which have or might have resulted in injury or in damage, as is done in most railway statistics : the qualification "unexpected" or "unforeseen" can then only be considered in relation to the regular operation of the railway and refer to an event not forming a link in the chain of operations regularly planned for the running of trains or connected therewith. The casualty will always be connected from the point of view of the injured with an event unexpected by him : the individually unexpected event. This event, however, may be, and frequently is, also an event unforeseen _ 5 — from the technical point of view of the regular working of the railway, i.e. an event disturbing the operation. This latter kind of event connected with a disturbance may result in several injuries, and thus become a statistical unit independent of the casualty. The term "accident" is applied in British railway statistics exclusively to the disturbance, irrespective of whether the event resulted in injury or damage. Wherever such an event cannot be stated, only casualties are registered. In Bulgarian statistics, the term "accident" is also confined to disturbances in operation. In other statistics, however, the term "accident" is generally taken to indicate the event as distinct from the injury, and covers not only events which are disturbances of operation, but also the personal events 1 where no disturbance is involved. In the United States, for instance, accidents are separately registered in all cases of injury occurring in connection with the operation or movement of trains, in addition to those cases where disturbing events occur. These latter are reported provided they result in injury or damage of more than 150 dollars. In German statistics the "accidents" (Betriebsunfälle) registered as separate units are the disturbing events and personal events which are connected with the movement of trains. Disturbing events not resulting in injury are registered if they occur during or as a result of the movement of trains, for instance derailments and collisions, and certain other disturbances involving the train in motion, and generally such as result in damage of more than 1,000 marks. Most other countries have similar methods : events not resulting in injury are registered if they are unexpected disturbances, a limit being usually fixed for the reporting of certain cases by stating the amount of damage which must result in order to make the event reportable. This limit varies from country to country, being, for instance, 1,000 francs in Switzerland, 10 kroner in Norway, 1,000 kronor in Sweden, etc. To sum up, therefore, the unit "accident" (Betriebsunfall, accident) refers in all statistics to events constituting unforeseen disturbances in the operation of the railway; in most countries, however, it covers also events which are only personal and have resulted in injury. As to the disturbances, the definition of reportable accidents varies with regard to the minimum amount of damage making an 1 It is interesting to note that the term "personal accident" (accident individuel) is found in French statistics. — 6 — event reportable and with regard to the specific kinds of events reported. The number of accidents reported therefore varies greatly from country to country and cannot be generally compared, though certain categories, such as derailments, collisions, etc., may be comparable. Distinction is not even always made between accidents which have resulted in injury and other accidents. Though disturbing events are certainly of interest for preventive purposes, the risk of the persons concerned appears only from the number of casualties. If all unexpected disturbing events are reported as separate units, without special tabulation of those resulting in casualties, the frequency of accidents resulting in injury cannot be stated, since accidents may result in injury to few or many persons. As regards the personal risks, i.e. casualties, the methods of reporting differ considerably. Even with so-called fatal casualties, the meaning of "fatal" differs, as it depends largely upon the method by which the causal relation between the event and death is established. While in Great Britain all casualties leading to death up to the date of the Annual Report are classified as fatal, many countries consider as fatal only casualties resulting in death within twenty-four hours from the occurrence of the accident, for instance, Switzerland, Germany, the United States, Austria, and Norway. In the United States Railway Accident Report for 1924, a table was introduced for "subsequent fatalities", i.e. those casualties which resulted in death after the expiration of twenty-four hours and which were consequently included among non-fatal casualties in the regular tables. The effect of the twenty-four-hour limitation in the regular tables may thus be illustrated as follows : EMPLOYEES ON DUTY KILLED AND INJURED IN TRAIN AND TRAIN SERVICE ACCIDENTS Men killed First method Second m e t h o d 1 l Men injured Number Rato per mil:; on locomotive miles Number Rate per million locomotive miles 1,192 1,339 0.69 0.78 32,174 32,027 18.64 18.55 For explanation of train and train service, see below. _ 7 — One hundred and forty-seven persons injured died after twenty-four hours from the time of the accident and were, therefore, included among the "injured" by the usual method (first method). If these persons are included among the "killed", the fatal casualty rate per million locomotive miles rises from 0.69 to 0.78, and the non-fatal casualty rate falls from 18.64 to 18.55. While, therefore, the non-fatal rate is not considerably modified by the exclusion of persons dying more than twenty-four hours after the accident, the fatal rate is 11.3 per cent, higher by the second method. The differences, however, in the limits of reportable casualties are far greater in regard to non-fatal casualties reported : in the United Kingdom, for instance, casualties which cause the railway servant to be absent for at least one whole day from his ordinary work are required to be reported; the limit of incapacity to work is fourteen days in Germany, Sweden, and Switzerland, twenty days in France, two weeks in Austria, etc., whilst in the United States the casualty must have led to three days of incapacity within the ten days following the accident. In Norway the casualty must have led to medical treatment in order to be reportable. Complete incomparabihty thus results for non-fatal railway casualties. T H E INDUSTRIAL R I S K The primary aim of this Report is an analysis of the statistics with a view to the determination of the railway industrial risk — i.e. the risk of employment in railway service. Contrary to the position in most other industries, however, accident risk on railways is not confined to the workers engaged in railway service. Accidents may also happen to passengers and other persons. I t is therefore necessary to distinguish : (1) an industrial, and (2) a non-industrial or public railway risk. Public safety and safety of employment in railway work are the two points of interest for special railway accident statistics. The public risk is of interest mainly in connection with the running of trains ; in other words, it is the risk t o the public resulting from unforeseen disturbances of the regular operation of railways. Casualties of passengers connected otherwise with the movement of trains are also usually considered as railway risks. The industrial risk, on the other hand — the risk incurred by railway workers during their employment — is made up of all casualties occurring during their work, whether arising — 8 — out of disturbances in the operation of the railway or by or during the movement of trains, or otherwise. The scope of the special railway statistics in some countries has been determined mainly from the point of view of public safety in regard to the risk peculiar to the running of trains, that is to say, from the operative point of view. In other countries, however, the scope of the statistics has been extended so as to cover all risks of employment of workers engaged in railway working, the industrial point of view predominating. The fact that railway accident statistics are not solely compiled with a view to determining the industrial risks of railway service has given rise to considerable differences in the demarcation of the statistics. (1) The notion of "railway risk" may be conceived in a narrow sense. According to this, the public safety point of view prevails and only risks arising from the actual process of running trains in the narrowest sense are covered. The criterion here is the movement of trains. (2) Where the industrial risk of the workers is considered of main interest for the special statistics, the wider conception of railway transport determines the scope of the statistics. In this case the criterion may be either : (a) a technical one, the operation of the railway — i.e. the processes during or by which the accidents happen — or (6) a local one — i.e. the premises serving for the operations of working the railway and on which the accidents happen. (3) A still wider conception of railway risk prevails where the financial criterion is accepted, i.e. the enterprise on the premises of which, or to the employees of which, the accidents happen. I. — In German, Swedish, Bulgarian, Australian and Swiss statistics, the movement criterion is applied 1 . Accidents are only reported if they happen by or during the movement of trains. Thus, on the one hand, disturbing events in the operation are not registered as accidents if they happen while the train is not in 1 In Switzerland, the statistics moreover include casualties due to electric current. motion 1 . On the other hand, events which are not connected with disturbances but lead to injury of persons are only noted if they occur in connection with the movement of trains. Coupling and uncoupling accidents, falls from trains, accidents whilst attending to locomotives, etc., are not reported if the train is stationary, nor are accidents registered which occur on the railway premises but not on the train or by train movements ; accidents while crossing the rails, setting points, signalling, etc., are then excluded. I t is to be borne in mind t h a t in most of these statistics the reported "accidents" extend also to the personal events resulting in injury, and not merely to disturbances in the operation of trains. As to casualties, the method of adopting movement as the criterion does not primarily take account of the status of the persons injured. The persons covered by the statistics are those injured in the accidents reported. The casualties reported are consequently those resulting from disturbing events or from personal events arising by or in connection with the movement of trains. The demarcation of the industrial risk of the workers employed in railway service is therefore made subsequently by classifying the persons injured in reportable accidents. The notion "railwaymen" however is not necessarily a clearly defined conception in this case. Workers exposed to railway risks in the above sense of movement risks may be : (1) Railway servants properly so-called, who comprise : (a) the more or less permanent employees of the railway companies or administration engaged in the regular train and station service, or (6) workers engaged in auxiliary establishments, such as workshops and repairing sheds, or workers carrying on auxiliary work on the lines, such as permanent-way men, where these are employed by the railway company, provided they are injured in a movement accident. (2) Workers temporarily engaged in work on or near the railway, but employed by contractors or other employers. (3) Workers whose duties are regularly performed on trains, e.g. postal officials, customs officers, etc., who, although they are 1 Pires in stationary trains or at stations, for instance, are not reported in the German statistics. On the other hand, all boiler explosions are included in Sweden and Germany. — 10 — not in any way engaged in the operation of the railway, may nevertheless be injured in movement accidents. Though casualties of all these categories may be included in the statistics, their employment risk is not fully reported, not even that of railwaymen properly so called. The persons covered are classified in the German statistics as "railway employees and railway workers on d u t y " and "postal, customs, telegraph, police and other employees on duty". In the Swedish statistics there is only a general group "railwaymen on duty". These classifications however do not demarcate the employment risk of these persons, but only certain specific risks incurred by them. This conception of railway risk, which is entirely inspired by the peculiar "movement nature" of railway risk, appears clearly from the following explanatory note in the German report : I t is of no account for purposes of accident statistics whether a worker who is working for a railway in operation is paid directly by the administration (of the railway) or whether he is employed and paid by an employer (contractor). In the latter case, the man, if injured during his work in consequence of the working of the railway, is also considered a railway worker on duty '. I I . — A wider conception of railway working, which provides for a more complete reporting of the industrial risks of railway workers, pi'evails in, for instance, the British, Noruiecjian, French and Belgian statistics. (a) The operations required for working the railway are the criteria in Norway, France, and other countries. In Norway, for instance, the accidents reported are the disturbances occurring in the running of trains engaged in ordinary and additional traffic and in the shunting required for this traffic, the so-called "accidents in railway transport properly so called", together with personal events occurring in this exploitation. The resulting casualties are tabulated as "casualties" and are classified as casualties of "railway servants on duty in train and shunting service" — t h a t is, persons engaged in running or shunting trains and employees working at stations or on the line in connection with such operations — and of "(other) railway servants on duty" — t h a t is, those not engaged in the running and shunting of trains, but 1 Statistik der im Betriebe befindlichen Eisenbahnen Deutschlands, No. 45, p. 306; Berlin, 1924. Accidents in railway shops are altogether excluded. — 11 — working on the railway and injured in or near a train, or during shunting operations. I t is evident t h a t in those cases where the injury is not connected with a disturbance of the operation, the answer to the question whether the corresponding event is to be included among "railway transport accidents" will depend on the nature of the operation in the course of which the worker was injured. In addition to these railway transport casualties, the casualties occurring in operations required for the working of the line, but not directly connected with the running of trains, are registered separately — for instance, accidents in workyards, while working on the maintenance of the line, during construction work, etc. By this method the employment risk of railway workers is represented by three groups : casualties of railway servants on duty in train and shunting service ; casualties of railway servants on duty in other railway transport services properly so-called ; and casualties of railway servants in other than exploitation services. (b) The place where the accident happens and the operation are the criteria applied in British statistics. The notion of accident, which, as will be remembered, is limited to disturbances of operation, covers all events, failures, disturbances, and defects involving the train, the rolling stock, and the permanent way — t h a t is, all disturbances on the premises or defects of the premises on which the operations for working the railway are carried on. Casualties are : (i) those resulting from these accidents, and therefore from the operation of the railway, and, in addition, (ii) other casualties happening on the railway premises, whether caused by the movement of trains or not. "Railway premises" are taken to be all premises used for the working of the railway; the working of the railway being taken in the sense of all operations directly serving the transport of goods and persons, or designed for securing this service. Stations, permanent way, goods yards, sidings, etc., are thus included, while workshops, factories, warehouses, repairing sheds, hotels and other premises only indirectly connected with railway transport, are excluded. The employment risk is then isolated by grouping all railway servants of the companies and of contractors as distinguished from passengers and other persons. "Other persons" include those on business at stations and in sidings. By this method, therefore, the total employment risk of railwaymen, t h a t is, of persons directly engaged in railway transport service or its proper maintenance, is covered. "Railway servants", — 12 — in British statistics, however, include all workers and officers employed by the companies, i.e. by the enterprise, even auxiliary staff, as canal staff, dock staff, hotel staff, as well as mechanics, artisans and the like who are not mainly or always working on railway premises. These workers incur casualties which are not covered by the statistics of railway casualties, and their employment risk is therefore not fully represented. III. — A much wider conception of railway operation determines the scope of the United States railway accident statistics, namely, the railway enterprise. The operation of a railway is meant to include all operations "performed under the supervision of the carrier by its employees", including operations for the maintenance of equipment, roadway, buildings, etc., and for the construction of "additions, betterments, and new lines, when performed by its regular forces of employees ordinarily engaged in the construction, operation or maintenance of existing lines". In addition to the operation of trains, locomotives and cars, "facilities incidental to their operation, such as tracks, railway stations, depots, freight houses, warehouses, shops, coaling stations, wharves and ferries, etc." are covered 1. As to accidents in the sense of unexpected events, only those occurring in connection with the operation or movement of trains, cars or locomotives, are reported 2 , including disturbing events causing damage of more than 150 dollars, as well as other disturbances and personal events resulting in injury. Casualties, however, cover all casualties of railway employees, including those not connected with the movement or operation of trains, cars or locomotives, and, in addition, all casualties of other employees of the railway company engaged not in railway working but in industrial work connected with the railway. A detailed classification by occupation and occupational groups demarcates the employment risks of the various categories of workers. It thus appears that comparability of accident statistics is quite impaired by differences in the methods of demarcation. 1 INTERSTATE COMMERCE COMMISSION, BUREAU OF STATISTICS : Rules Governing Monthly Reports oj Railway Accidents, 1922, p . 11. Revision, Washington, 1922. 2 "Operation" does not mean operation of the railway generally, only of the trains. — 13 — Unification in this respect would therefore be the first and essential requirement in order to render the statistics comparable internationally, and it appears from the foregoing analysis that the most appropriate demarcation of the risks of working a railway would be achieved by applying the criterion "premises serving for the working of the railway and its maintenance". There may still be doubtful cases as to what operations are to be considered as forming part of the working of the railway — for instance, whether workshops and repairing sheds should be included. As these are on the whole industrial premises, it would seem more appropriate to exclude them. By this method all disturbances in the operation of the railway would be covered, while all casualties happening on the premises would be included. The total industrial risk of the workers engaged in the working of the railway and its maintenance, as distinct from the risk of other workers, could then be assessed by means of a classification which would combine all such workers together in a separate group. I t is evident t h a t the risks of railway workers differ considerably according as to whether their work brings them more closely into touch with the actual operation of trains, cars and locomotives, or whether they are mainly engaged in work on stations or in other auxiliary jobs. These differences of risk may be viewed from two standpoints : (1) the risks peculiar to the running of trains may be distinguished from the risks of railway working generally, which are partly of an industrial character; (2) the risks of the several occupational groups may be distinguished. T H E RAILWAY R I S K GROUPS The risk of railway working may be specified according to its direct or indirect connection with the running of trains, and in particular with the movement of railway rolling stock. In the railway statistics of Great Britain, only events which constitute disturbances in the regular working of the railway are summarised under the heading "train accidents", personal events not being registered as accidents. Disturbances are subdivided into "accidents to trains", which comprise mainly movement accidents, and "accidents to or failure of rolling stock or permanent way". These train accidents constitute, in fact, the risk peculiar to railway working. The casualties resulting from these accidents are termed "train casualties". This group, therefore, represents the risk of railway 2 _ 14 — workers due to improper or defective working of the railway. Other casualties occurring on the railway premises, but not connected with disturbing events, are then specified in regard to their connection with the movement of trains, and are classified as "movement" and "non-movement" casualties. Casualties of a similar nature m a y be tabulated in the one or the other group according as to whether they are connected or not connected with the movement of trains. The complete classification is, therefore, as follows : (1) Accidents : (a) train; (b) rolling stock and permanent way. (2) Casualties : (a) train; (b) movement ; (c) non-movement. Train and movement casualties are then combined as together constituting the more essential railway risk. I n the United States steam railway statistics the three groups, "train", "train service", and "non-train" accidents, do not correspond entirely with the three British groups. As to accidents, the group "train accidents" covers disturbances in the regular working of the railway, but only those which result in damage in excess of 150 dollars to equipment or other railway property and which arise in connection with the operation or movement of trains, locomotives or cars. The group "train service accidents" comprises those disturbing events which result in injury, but which do not cause damage in excess of 150 dollars, together with personal events resulting in injury, if these events arise in connection with the movement or operation of trains, locomotives or cars. Casualties are grouped as those resulting from train accidents. on the one and, hand as "train service casualties" on the other. The latter group refers mainly to casualties resulting from personal events connected with the movement of trains and includes casualties resulting from disturbing events in as far as the damage involved is not more t h a n 150 dollars. Moreover, it comprises casualties not connected with the movement of trains — "non-movement" casualties — provided they occur during work on or near trains or cars or locomotives, i.e. in their "operation". The third group of casualties, the "non-train casualties",. comprises all other casualties which occur during work carried on by the employees of the carrier, and therefore covers the non- — 15 — movement casualties of railway workers arising during the working of the railway and not included in the group of train service accidents 1. In Norway a group of "train accidents" is distinguished, including all disturbing events happening in the running of trains for ordinary traffic which result or might have resulted in injury to persons or damage. The group "other accidents" includes accidents in shunting (events which result in damage or injury, whether disturbances. or personal events) and other personal events which occur in the running of trains. Casualties are grouped into train casualties — t h a t is, those resulting from train accidents — and into other movement and non-movement casualties occurring in the running or shunting of trains (exploitation) ; casualties other than in railway transport properly so called are given separately. In Canadian statistics, which report casualties only, casualties resulting from the movement of trains and casualties resulting from causes other than the movement of trains are distinguished. I n those statistics which include movement accidents and casualties only, accidents are usually classified as collisions, derailments, and other accidents, the two former groups being evidently considered as comprising the main train accidents. The third group covers all disturbing events reported which are not included in the former groups, together with personal events connected with movement and resulting in injury. With regard to casualties, the same main groups as for accidents are employed for casualties in Bulgarian, Polish, Sivedish and other statistics, and were adopted in the German statistics up to 1921, while from 1922 onwards casualties have only been grouped as casualties from train accidents and casualties from other accidents, the former group comprising derailments and collisions. The latter practice is also adopted in Switzerland. Other countries again, such as Portugal, the Netherlands, Hungary, Czechoslovakia, France, etc., distinguish derailments, collisions and other accidents with regard to accidents, but do not extend this classification to casualties. I n some of these countries, however — for instance, in France, Czechoslovakia, and Italy — the third group "other accidents" is not of the same scope 1 "Non-train" casualties, moreover, comprise also various kinds of industrial casualties which occur in establishments not belonging to the railway premises properly so-called. — 16 — as in the German or Swedish statistics, as it includes not only movement accidents but also certain non-movement accidents. The French statistics 1 distinguish casualties resulting from train accidents, casualties resulting from other accidents occurring in the working of the railway (de faits d'exploitation autres que les accidents de train) and casualties caused by imprudence or misadventure. I n Belgium, which confines accidents to derailments and collisions, casualties resulting from derailments and collisions are given in the same group, while casualties resulting from other accidents reported form a separate group. To conclude, it would appear t h a t a clear demarcation between the more specific railway risks and the more general railway risks might be based on a distinction between disturbing events (accidents) on the one hand, and casualties (cases of injury) on the other. Accidents might with advantage be confined to disturbances in the working of railways generally. I n cases where the event is strictly personal the accident is identical with the case of injury, and not really of interest as a separate unit, as the number of such accidents is the same as the number of casualties. The purpose of prevention, therefore, seems adequately served by registering only the disturbing events, and their comparison with the resulting casualties will show the frequency of collective accidents. I t would seem, however, t h a t some definition as to reportable "disturbing events" should be agreed upon in order t h a t the statistics may be comparable from country to country. The registration of any disturbing event in the regular working of railways would leave too much scope for discretion. I n principle, all disturbances due to derailments and collisions might be registered. Otherwise a reportable accident might be defined internationally as an event occurring on railway premises which disturbs the operation of the railway, provided t h a t it results in injury to a person or persons or damage to thé railway property of at least, say, £50 or 1,000 marks or 200 dollars. These accidents could then be termed railway operation accidents, a group which would differ from the British group, as the latter includes also events not causing damage of more than £50 or injury to persons, and from the United States group, as the latter includes only events involving trains, cars, or locomotives. 1 Statistique des Chemins de fer français. — 17 — I t would seem advisable to subdivide these accidents into : (1) movement and (2) non-movement accidents. Movement accidents would include all disturbing events involving the train in motion or cars or locomotives in motion. Non-movement accidents would include all other accidents in the working of the railway occurring on the premises. The casualties would be : (1) railway operation casualties, i.e. those resulting from railway operation accidents; (2) other casualties, i.e. those occurring in the working of railways, but not resulting from accidents in the sense defined. Both groups would then be subdivided into : (a) movement, and (6) non-movement casualties, the former group (railway operation casualties) according to the character of the accident from which they result, and the latter (other casualties) according to whether or not the personal event was connected with the movement of trains or cars in a causal sense. The non-movement casualties of the second group would comprise all other casualties on the premises not resulting from accidents 1. Group 1 (a) and 2 (a) could then be combined as representing the typical railway risk, i.e. movement casualties. T H E EMPLOYMENT R I S K GROUTS By grouping, on the lines indicated above, the specific and general risks of railway working, no account was taken of the industrial risks of the different categories of workers exposed. We have seen t h a t railwaymen properly so-called, i.e. those actually employed in the working of the railway, are sometimes isolated in the special statistics from other workers exposed to railway risks, whereby the question whether they are employed by the railway company or administration or by a contractor is considered of secondary importance. These railway servants properly so-called, however, are unequally exposed according to their occupation to the different kinds of railway risks, viz. railway operation casualties, or movement and non-movement casualties. Those mainly engaged on the train will be most exposed to movement casualties — the most characteristic of railway risks. Of those working on the line and on stations, the exposure to movement risk will be the greater the more their duties cause them to be on the line. Railway clerks, 1 I t should be noted that the groups "railway operation casualties" and "other casualties" do not correspond to the two groups "train accidents" and "train service accidents" in the United States statistics. — 18 — for instance, will be hardly exposed at all to movement risks, nor will station-masters or carmen be much, exposed, and even signalmen are not greatly endangered by the movement of trains. As a rule, the total risk of any of these occupations is higher according as the workers are more exposed to movement risks, though this is not necessarily so. The following table taken from the United States railway statistics illustrates the risks of various selected occupations classified according to the risk groups 1.

Non-fatal casualty rates do not always vary in similar manner to fatal rates, but the highest fatal rate and the highest non-fatal rate are both those of yard brakesmen, while the next highest rates are those of road freight brakesmen and flagmen (local and way freight). Employment risk on railways is, in fact, so unevenly distributed t h a t a general rate for all railway workers would appear of little value. A classification at least by categories of workers according to their main jobs seems indispensable. Nevertheless, many countries have not classified casualties by occupations or even occupational groups. A very summary grouping into "railway employees and auxiliary workers" and "railway workers" was made in German statistics up to 1921. In Norway, railway workers are classified, as has been shown, into "railway servants engaged in train and shunting service" and " (other )railway servants on duty" — comprising the other railway workers — but both groups refer only to "exploitation accidents" (running and shunting of trains). In the British statistics, thirty-five occupations of railway companies' servants are distinguished, both for train and movement casualties together, and for non-movement casualties. The workers engaged on the most characteristic railway work are classified in some detail, whilst those less exposed to railway risks, and not really railway workers in the sense of workers constantly engaged on railway premises, are more summarily grouped. The final group "miscellaneous" comprised in 1925 no less than 76,115 adults, who had only 9 fatal and 146 non-fatal train and movement casualties while the total figures for this class of casualties were : railway employees 703,532; fatal casualties 251, non-fatal casualties 3,659. Non-movement casualties for the two groups were as follows : miscellaneous employees : fatal casualties 1, non-fatal casualties 801; all employees : fatal casualties 37, non-fatal casualties 17,556. I t will be remembered t h a t the "miscellaneous" group comprises various kinds of workers employed by the railway companies but engaged in work which may be only remotely connected with railway operation. In the United States railway accident statistics, casualties are subdivided into no fewer than 148 occupations which include, however, all workers employed by the railway companies, not only — 20 — railway workers. These occupations are summarised into seven groups : (i) executives, officials and staff assistants ; (ii) professional, clerical and general ; (iii) maintenance of the way and structure ; (iv) maintenance of equipment and stores ; (v) transportation (other than train, engine and yard) ; (vi) (a) transportation (yard masters, switch tenders, hostlers); (vi) (6) transportation (train and engine). The latter group is also termed "trainmen" for whom special statistics are given. Another report, Statistics of Industrial Accidents, published by the Bureau of Labour Statistics, giving a summary of railway statistics, classifies railway workers into six groups : trainmen, shopmen, stationmen, trackmen, bridge and building men, and other employees. In Belgium, workers in stations and shops, workers engaged in coupling and uncoupling, gatekeepers, watchmen, ticket controllers, trainmen (guards, enginemen and firemen), workers repairing the permanent way and buildings, and "persons employed in other departments", are distinguished 1 . A classification of occupations suitable for international comparison should primarily group those workers exposed to similar risks. Above all, the number of workers engaged on the trains or locomotives should be given separately. Among these, distinction should be drawn between trainmen properly so-called, such as enginemen, motormen, firemen, brakesmen and guards, engaged in running the train, and auxiliary workers travelling on the train, such as waiters, cooks, stewards, and postal workers permanently engaged for train service. Secondly, railway servants engaged in work on the stations or on the line may be grouped together : among these, however, a distinction should be made between workers engaged in shunting and those in other train service, and among the latter again between those directly engaged in train service and slightly exposed to train movement risks, e.g. station masters and porters on the one hand, and office workers (clerks) mainly working inside buildings and hardly exposed to specific railway risks on the other. A third category would be workers engaged in maintaining the permanent way, the structure, buildings, etc., those repairing the track as well as those repairing or rebuilding bridges, station buildings, etc., and exposed to railway risks during their work on the premises. From these, however, should be distinguished artisans, mechanics, 1 "Servants not on d u t y " form a group corresponding to those mentioned above. — 21 — and other labourers who do not usually work on railway premises but in shops, goods yards, repairing sheds, etc., and who may be victims of railway accidents or casualties as a result of occasional presence on railway premises. The employment risk of these workers is not fully represented by their accidents on railway premises, and if their risk is to be calculated casualties which occur during their employment on other premises should also be taken into account. The following classification is thus suggested. The classification does not include workers travelling on the train or present on railway premises in pursuance of duties in other than railway service, such as postal, customs, telegraph and other workers, so far as these are not permanently or temporarily working for the railway.

IV. — RAILWAY SERVANTS NOT EXCLUSIVELY ENGAGED ON RAILWAY PREMISES (INCLUDING WORKSHOP STAFF) * * Railway workers may have casualties whilst not on duty but present on railway premises for some reason or other. Such casualties are usually shown separately, or sometimes included among casualties of persons other than railway servants and passengers. It would seem advisable to report them separately, as they complete the picture of the risks incurred by railway workers owing to their occupation. Railway casualties of workers whilst not on duty are also peculiar to railway service. Railway workers may be present on the premises after their hours of duty have been completed. CHAPTER I I RAILWAY ACCIDENT EXPOSURE In order to measure the industrial risk of railway workers and to compare their risks in different countries, the number of casualties must be related to some units of exposure. Two kinds of measures of exposure are found in railway accident statistics : 1. Those representing the exposure to all kinds of risks involved in railway service, the measures being : (a) the average number of railwaymen, (6) the number of man-hours worked. 2. Those applicable only to the particular risks connected with the movement of trains, the mileage run being taken as special measure of exposure. Rates per mileage m a y be based on three measures : (a) the train mileage ; (6) the locomotive mileage; (c) the car (axle) mileage. T H E AVERAGE N U M B E R EMPLOYED OR M A N - H O U R S W O R K E D The staff of a railway differs in two respects from the working force in other industries. On the one hand, the railway servants proper, i.e. those employed by the railway company or administration for the regular train service, are somewhat in the position of State employees. They constitute largely an almost stable permanent staff, and labour turnover is small. By the nature of the service, these railway servants are required to be regularly on duty. Days, therefore, will, as a rule, be lost on account of leave or sickness only. For this staff, consequently, t h e average number, as compiled from the employment lists of the railway companies or administrations, will fairly accurately represent the relative exposure on a given railway, as the staff is not only permanent, but railway servants on ordinary leave or sick leave will remain recorded in the pay-books. On the other hand, work for the railway (other than that required to regulate traffic) may be carried on partly by workers employed — 24 — by the railway company or administration temporarily or by another employer (contractor) undertaking work for the railway. Building and repairing, for example, may be carried on by such temporary workers in so far as it is not performed by the regular staff. Moreover, the permanent staff of the railway companies will comprise workers, such as artisans and mechanics, who are to a large extent engaged in work on other t h a n railway premises, for instance, in workshops and repairing sheds, and who are in consequence only occasionally exposed to railway accidents. The average number of these workers therefore cannot be taken as representing the exposure to railway risk. The fact t h a t they are employed by the railway company or administration does not make them "railway" workers. As regards workers temporarily engaged in railway work, their exposure can only be measured by adding up the time during which they work for the railway in a given period. I n the case of the permanent staff of a railway mainly or partly employed otherwise than on railway premises, it will be difficult to measure their exposure to railway risks as the time which they actually spend on the railway premises can hardly be determined. If the proportion of these workers as compared with all workers and the proportion of their time spent on railway premises as compared with their total time worked were the same in all cases and countries compared, their inclusion in the exposure would not affect the comparability of the rates. This, however, cannot be assumed to be the case. I n calculating summary rates for railway workers, these auxiliary workers should not be included, nor would it seem of any great value to calculate separate rates for this auxiliary staff, since other non-railway casualties occurring during their employment would have to be given elsewhere than in railway accident statistics. Their railway casualties might be given separately. Owing to these various difficulties of calculating the exposure of railway workers, and owing also t o the fact t h a t many statistics do not cover all railway risks (i.e. all casualties on railway premises), but only movement risks or those in certain operations, rates per average number of railwaymen are not often calculated. In Sweden, where the statistics cover movement accidents and casualties only, rates of fatal and non-fatal casualties per thousand railwaymen are calculated. The average number of workers — 25 — is computed from monthly returns in the district chief's reports, and includes not only the ordinary and temporary staff engaged by the railway for the performance of service, b u t any workers carrying out work for the railway, whether they are paid directly by the railway or by contractors. In the French statistics (Annales des Ponts et Chaussées and Annales des Mines), fatal and non-fatal casualty rates per 1,000 railway employees are calculated. In the United States statistics, account is taken of differences in the risks of various categories of railwaymen. The number of employees in service per employee killed and injured and separate rates for trainmen only are calculated. Moreover, rates per thousand men are published for the different categories of trainmen separately. The numbers of railwaymen and trainmen in service are computed from monthly statements and include all employees on duty as well as "employees under pay on vacation or sick leave"; employees, however, who are not subject to call for duty, "such as employees not under pay, absent on definite leave or under suspension, and pensioners not bound to render service" are excluded. Certain difficulties may arise with regard to the classification of exposure t o risk of the workers by occupation. This classification must, of course, correspond to the grouping of casualties by occupation. Some workers however may do certain jobs in turn, as driving freight and passenger trains. The American rules provide that, in calculating the exposure, employees whose duties are such as to make them liable t o inclusion in two or more divisions should be included in t h a t division indicated by the greater part of their time during the month *. For the tabulation of casualties, however, the character of the work at the time of the accident is decisive. The measurement of exposure by the average number of workers employed is, however, open to the objection t h a t the individual days worked and the hours actually worked by the employees may differ. Although the man-days worked or spent on duty, and therefore the hours worked, by an equal number of employees of a given railway in two periods may be fairly comparable, yet the days and 1 INTERSTATE COMMERCE COMMISSION : Rules Governing the Classification of Railway Employees and Reports of their Service and, Compensation : Effective on 1 July 1921, p . 11. Washington, 1921. — 26 — hours of work may differ considerably from country to country, a,nd even as between the different occupations of a railway (cf. page 29). In order to render statistics internationally comparable, rates should therefore be calculated per man-hours worked; account is thus taken of differences in man-days worked and in the length of the working day. Rates per man-hours worked are calculated in the United States statistics for each category of workers. T H E MILEAGE RUN Far more frequent, however, than rates per average number of workers employed or per hours worked are rates per mileage applied to movement risks. Rates per million train kilometres and per million car kilometres were calculated in German statistics for railwaymen and railway employees on duty. In Swiss statistics, rates per hundred thousand locomotive kilometres and per million car kilometres are published for railway employees. I n Sweden rates per train kilometres and per car kilometres are published, in addition to those per thousand employees. I n the United States statistics, fatal and non-fatal casualty rates per million locomotive miles are calculated for train and train service accidents of all employees. Moreover, rates per ten million freight miles are calculated for freight trainmen and similar rates for passenger trainmen. I n Norway train and shunting casualties are related to one million train kilometres. In Bulgarian statistics rates are given per one million train kilometres and per ten million axle kilometres, etc. Mileage rates are usually calculated for those casualties only which result from the running of trains, for instance movement risks in Germany, Sweden and Switzerland, and movement risks together with other risks in the operation of trains, cars, etc., e.g. in the United States and Norway. By referring the number of casualties to the mileage run by trains, locomotives or cars, the risk connected with a certain amount of output is no doubt measured in so far as mileage can be considered as output, irrespective of the number of passengers and the quantity of goods carried. If, however, the mileage run is to be considered as a measure of exposure, allowing a comparison of the risks of railwaymen on different railways or at different dates or for different categories of workers, it would have to be — 27 — proved either : (1) t h a t the mileage is a direct factor of exposure, i.e. t h a t the number of casualties varies in proportion with the mileage run; or, if this cannot be proved, (2) t h a t the mileage run is an indirect measure of the time worked or the average number of workers, i.e. these two factors must vary in proportion with the mileage run. The second alternative may be considered first. Is the mileage run an indirect measure of time worked or of the numbers employed ? (a) Within a country and within certain limits the relation between the numbers employed and the mileage run may be fairly constant, but experience shows that a considerable increase in traffic and mileage run can be effected without a proportionate increase in the number of, or the time worked by, men not directly engaged on the train. Moreover, the quicker the trains the fewer will be the trainmen or trainmen-hours required to run a certain mileage. If these objections can be raised as regards any one country, they will be even more valid in regard to comparison of risks in different countries. The number of trainmen required t o run a certain mileage may differ according to the average length of the trains as well as the average speed. Further, the general staff, other than trainmen, required per mileage run will evidently be greater the more numerous the stations as compared with the length of the road. The density of stations is, of course, a function of the density of the population. Thus, the train mileage run per employee was 700 miles (1,126 kilometres) in the United States (1925) and 734 kilometres in Germany (1925); that is, about one and a half times greater in the United States 1. This is no doubt largely due to the greater distance between stations in the United States. I t may also be due partly to a greater average speed in t h a t country. The mileage run cannot therefore be considered as an indirect measure of the time worked or the average number of employees. (6) In order t h a t mileage rates should provide a satisfactory measure of the risk of railwaymen, it would be necessary to show 1 United States: Freight, passenger and work train miles: 1,220,845,788; number of employees : 1,744,311. Qermany : Train kilometres : 549,946,274 ; number of employees : 749,638. The difference would be still greater if in the United States only railwaymen properly so called were taken into account. — 28 — t h a t the number of casualties varies in proportion with the mileage run ; this would mean t h a t the risk does not depend on the number of railwaymen or the time worked, nor on the time taken by the train to run a certain mileage, i.e. on the speed. Data based on mileage rates are available only for the United States. The tables below give the number of trainmen employed, of train miles run, of casualties, and the risks of freight trainmen and passenger trainmen. The number of freight trainmen is more than twice as great as the number of passenger trainmen, while the mileage run is only slightly less in the case of passenger trains. A greater number of freight trainmen is necessarily required to run the same mileage, as freight trains are much slower and therefore more freight trains or more time respectively are necessary to run the same total mileage. I t is a striking fact t h a t the casualty rate per ten million miles is much higher for freight trainmen than for passenger trainmen. The proportion between the casualties of freight trainmen and the casualties of passenger trainmen far exceeds the proportion between the mileage run b y freight trains and the mileage run b y passenger trains. The great differences in the mileage rates therefore are most likely due mainly to differences in the number of men employed or man-time worked. However, the risk per men employed also is greater for freight trainmen than for passenger trainmen, and this difference appears throughout the years of observation. I t suggests the presence of another factor working to the detriment of freight trainmen. I t might be assumed t h a t speed has some influence on the rates, as the speed of the trains is t h e main difference in regard t o freight and passenger trains. Statistics of fatal casualties in train and train service accidents of trainmen in the United States from 1916 t o 1924 and of fatal casualties in train and train service accidents by occupations in 1924 are given in the following tables. — 29 — UNITED STATES. — CLASS I ROADS : FATAL CASUALTIES I N TRAIN AND TRAIN SERVICE ACCIDENTS OF TRAINMEN, 1 9 1 6 TO 1 9 2 4 1 Train Number of miles casualties (in 1,000) Year Trains'1 Freight 1916 1917 1918 1919 1920 1921 1922 1923 1924 681 760 847 509 605 302 328 436 295 693,671 705,167 690,046 614,095 675,788 561,372 587,950 683,481 631,256 Passenger 1916 1917 1918 1919 1920 1921 1922 1923 1924 1 113 136 150 128 147 94 97 109 81 INTERSTATE COMMERCE Number R a t e per R a t e per of 10 million 1,000 trainmen miles trainmen 154,027 165,953 169,819 151,015 163,774 137,852 141,879 163,292 149,764 9.8 10.8 12.27 8.28 8.9 5.4 5.6 6.38 4.67 4.42 4.58 4.99 3.37 3.69 2.19 2.31 2.67 1.97 1,96 2.36 2.83 2.37 2.62 1.69 1.79 1.94 1.46 1.96 2.37 2.71 2.32 2.54 1.64 1.71 1.88 1.41 Trains 576,094 575,500 529,444 539,803 561,633 554,805 541,275 560,980 553,253 57,611 57,435 55,366 55,282 57,858 57,304 56,660 57,981 57,596 COMMISSION, B U R E A U OF STATISTICS : Accident Bulletin , N ° 9 3 , pp. 7, 8, 112.

On the contrary, the rates of passenger enginemen and motormen and of passenger firemen are about double those of freight enginemen and firemen respectively. B u t the risk of freight conductors is about five times greater than t h a t of passenger conductors and the risk of freight brakesmen three times t h a t of passenger brakesmen. An attempt may be made to explain these facts. Enginemen and firemen are engaged on the locomotive. The speed of a passenger train being much greater, any accident involving the passenger train is likely to have more serious effects than a similar accident to a freight train for those who are mainly exposed, viz. the locomotive men. The greater speed would mean for these workers greater exposure to risk. This assumption seems to be confirmed by the following facts : (a) If rates are calculated separately for through freight and local and way freight enginemen and firemen, it appears t h a t rates for through freight trainmen are higher than those for local freight trainmen (rates per man-hours). Through freight engineers and motormen Local and way freight engineers and motormen Through freight firemen and helpers Local and way freight firemen and helpers 0.52 0.31 0.54 0.48 (6) The higher rates for passenger enginemen and firemen are mainly due to the greater number of casualties in railway operation accidents and among these particularly derailments. There may be two explanations of the greater number of these casualties : either passenger trains have more train accidents or derailments respectively than freight trains, or the accidents have more serious consequences for passenger trainmen on account of the speed. The latter explanation seems the more valid as a greater number of derailments is found for freight trains, even if it is taken into account t h a t a much greater number of freight trains is required to run the same mileage. The case is very different in regard to conductors and brakesmen. The rates per man-hours for these trainmen are very much higher with freight trainmen than with passenger trainmen, though the speed of passenger trains is much higher. I t would seem, therefore, t h a t in this case personal events are the predominant source of danger, or the so-called "casualties arising from train service acci- — 31 — dents" of the American statistics, which correspond to movement and non-movement casualties in the sense adopted by the present study. The risk consequently appears to be rather diminished by speed as the slow and frequently stopping train evidently requires far more operations entailing train service risks, such as coupling, braking, switching, shunting, etc. In fact it is found t h a t the higher rates for freight brakesmen and conductors are mainly due to train service casualties, as the following figures show : FATAL TRAIN SERVICE CASUALTIES OP ROAD TRAINMEN PER MILLION MAN-HOURS Passenger conductors Freight conductors (through freight) Freight conductors (local and way freight) Passenger brakesmen Freight brakesmen (through freight) Freight brakesmen (local and way freight) 0.115 0.526 0.581 0.267 0.803 0.946 I t appears moreover t h a t the rates vary inversely as the speed, being highest for local and way freight brakesmen. I t must therefore be concluded that speed is an important factor of risk. To sum up, it seems t h a t mileage run is not a suitable measure of the rates of comparative risks of railwaymen. I t is, however, useful for the calculation of accident rates, measuring the frequency of disturbing events in relation to the "output". CHAPTER HICLASSIFICATION BY CAUSES An accident is usually due to a complexity of causes. The unexpected coincidence of contributory circumstances — events, acts, defects —• causes injury to life or damage to property, or both. For the purposes of accident prevention, it is less important to determine the causal relation than to specify those known circumstances which indicate how the accident might have been prevented. The classification of accidents and casualties by causes is therefore made from this point of view, and where a diversity of circumstances contribute to the accident, it may be necessary to introduce a collective notion indicating not the details of the occurrence, but the coincidence of different circumstances. Thus, on the railways the disturbing event in the operation which results in injury or damage, and which in the majority of cases might have been prevented, will be the main criterion. Different causes, for instance, of an accident or casualty may be concealed under the heading "derailment". I t is then the task of a further tabulation to specify the contributory circumstances which led to the derailment — and which may be termed secondary causes with reference to the casualty. The disturbance may have resulted from events outside the control of the persons engaged in regulating the railway service or from events or circumstances due to personal negligence. Acts, or failures to act, of persons or inadequate maintenance of the premises or equipment may be particularly frequent on railways. When injury is not the result of a disturbing event, it is often more difficult to speak of a cause. The injury is the result of coinciding circumstances which may, for the purpose of classification by causes, be termed "special circumstances" and are distinct from the nature of the work in which the person injured was engaged and from the railway operation during which the casualty happened. The special circumstances (for instance, run over by a train, slipping, struck by objects, etc.), though causes in the sense t h a t they have resulted in injury, do not always supply sufficient information for preventive purposes. The classification is therefore often completed by, or even confined to, an indication of the (1) nature of — 33 — the work, (2) the railway operation or (3) certain local circumstances which had a bearing on the casualty. The nature of the work is here meant to refer to the occupational activity in which the worker was engaged when the accident happened (not his occupation), while operation is meant to refer to the working of the railway in a technical sense. The nature of the work and the operation are of course not causes strictly speaking, and only by the coincidence of several factors, such as negligence, fatigue or haste on the part of the injured or on the p a r t of third persons, may they give rise to the injury. Finally, local circumstances may be of importance both for the causation of accidents and of casualties; for instance, the presence of a person on the track, the fact t h a t he is getting on or off an engine or car, etc. As in railway statistics the accidents (mainly disturbances of operation) are always recorded separately as statistical units, different classifications for accidents and for casualties are sometimes found. I t is better therefore to discuss first the classification of accidents by causes, then the corresponding classification of casualties, and finally to show how they are and might be combined 1 . T H E CLASSIFICATION OF ACCIDENTS The separate classification of accidents has a meaning only in regard to the disturbing events. In the other cases where the personal event is registered as an accident, the classification coincides, to a large extent, with that of casualties. We therefore discuss here the classification of railway operation accidents (disturbances) only. Accidents are always classified according to the nature of the disturbing event. In most statistics we find such main groups as derailments, collisions, boiler explosions and fires in trains. As noted above, in a number of countries — especially those which publish movement accidents only — three main groups of accidents are distinguished : derailments, collisions and other accidents. The group "other accidents" usually contains also the personal events registered as accidents. The accidents in the third group are in some countries further subdivided according to the nature of the event. In Swedish statistics, for instance, the group contains the subdivisions : running into vehicles, fire on trains, boiler 1 Some typical classifications will be found in the Appendix. — 34 — explosions and other accidents. These groups, however, are based on the same criterion as the classification of the main groups "derailments" and "collisions", viz. the nature of the accident. On the other hand, the subdivision of the main groups "derailments" and "collisions" is one by causes as above defined. The British classification, which includes all the disturbances on railway premises, not only those involving trains, is based on the distinction between accidents to trains and accidents to rolling stock and permanent way. The former group is summarily divided into five subgroups : derailments, collisions, running into obstructions, fires, and miscellaneous. The second group (accidents to rolling stock, permanent way, etc.) is classified either by the rolling stock or part of permanent way which was defective (for instance, failure of tyres, axles, tunnels, boilers or machinery) or by certain events such as fires in stations or on bridges, floodings, or slips. These groups are further specified either according to the technical nature of the rolling stock or to certain specifications of the defects or failures, etc., e.g. failure of tyres : tyres of engines, of tenders, etc., broken at screw or bolt holes, etc. I n the United States, collisions, derailments, locomotive boiler explosions and other locomotive accidents and miscellaneous accidents are distinguished as main groups. These main groups are generally subdivided according to various criteria : 1. I n the statistics of various countries derailments and collisions are often classified according to the rolling stock involved, this classification being sometimes extended to other accidents also. I n German statistics, for instance, up to 1921 collisions and derailments of passenger trains, freight trains and single vehicles or parts of trains engaged in shunting were distinguished. In Belgian statistics, derailments and collisions are given separately for passenger trains and for goods trains and light engines. I n British statistics, five groups of collisions and two groups of derailments are distinguished, according to the trains involved. I n the United States statistics, each group of railway operation accidents is divided into twelve classes according to the kind of trains or train compositions involved. I n the Swedish statistics, the distinction between derailments and collisions in train service and in shunting probably serves somewhat the same purpose, since it distinguishes the operation in which the train was engaged. 2. Subdivisions according to the place or rather to the local circumstances in which the accident occurred are frequently given, — 35 — either in combination with the kind of rolling stock involved or separately. Derailments and collisions on the road or in stations are distinguished in German, Swiss, Norwegian, Swedish, French, Italian and other statistics. Some indications of place are given in the British classification of collisions. I n the United States statistics, no classification by place is made, b u t the subdivision of collisions by so-called classes contains some references to place (see page 36). I n pre-war Belgian statistics 1, six groups of collisions were distinguished according to the place where the accident happened or the rolling stock involved. Derailments at stopping stations and derailments on the road or at stations where the train was not scheduled to stop were distinguished. 3. The subdivision of the main groups of accidents according to causes properly so called, t h a t is, by contributory circumstances, is usually based either on the defects of rolling stock or permanent way or on the acts, or failures to act, of employees t h a t caused the disturbing event. As in railway operation fault in the sense of negligence or wrong performance of duty can frequently be determined, the latter criterion is often applied — for instance, wrong setting of points, careless shunting or defective signalling. Not all countries give such subsidiary classification of accidents by causes. In British statistics the main groups of accidents arising in railway operation are only subdivided according to the rolling stock involved with but one reference to faults of the personnel (collisions of trains with buffer stops in consequence of too high a speed) 2 . I n the United States statistics two classifications of the main groups of railway operation accidents are found. A general classification is applied to all the main groups, containing very detailed subdivisions. The four summary groups of the general classification are as follows : (1) (2) (3) (4) Negligence of employees; Defects in or failure of equipment; Defects in or improper maintenance of way and structure ; Miscellaneous. These groups are divided in great detail into several hundred subgroups. Moreover, each main group of accidents is classified 1 Post-war statistics were much reduced and this classification discontinued. 2 See classification of casualties in train accidents, Appendix, table IV. — 36 — separately according to its particular nature. The classification of collisions is not one by causes, but is made either according to the place where the accident occurred or t o the circumstances in which the trains collided. The special classifications of the other main groups are by causes and partly summarise such detailed groups of the general classification as are of special importance for the main group in question. The classification reads as follows : UNITED STATES : CLASSIFICATION OF TBAIN ACCIDENTS Collisions : Rear-end. Head-on. Broken-train. Side or raking. Collisions at railway crossings : On private rights of way. On publie streets, etc. Trains with cars not in trains. Switching. Not elsewhere classifiable. Derailments due to : Defects in or failure of power-brake apparatus, hose, etc. Defects in or failures of couplers. Other defects in or failures of locomotives or cars. Defects in track, bridges, switches, and signals, or other defects in roadway. Accidental obstructions or defects in track due to fires, landslides, floods, etc. Obstructions at public highway crossings. Negligence, mistake, or misconduct of trainmen or other employees. Mistake or misconduct of persons other than employees. Ascertained causes not classifiable above. Unknown causes. Locomotive-Boiler Accidents : Shell explosions. Crown-sheet explosions, low water, no contributing causes. Crown-sheet explosions, low water, contributing causes. Other explosions. Tubing or pipes subject to steam pressure, defects in or failures of. Other boiler accidents. Other Locomotive Accidents : Failures or defects in : Cylinders. Driving gear and machinery. Wheels and axles of locomotives. Tenders. Miscellaneous. — 37 — Miscellaneous Train Accidents : Colliding with trolly-oars, automobiles, etc., at public highway crossings. Other miscellaneous train accidents. As to train service accidents, their classification coincides with the classification of train service casualties. In German statistics, up to 1921 collisions and derailments were classified either according to defects or t o wrong or negligent acts of employees. Swedish statistics have a classification by causes similar to t h a t of the former German statistics. I t reads as follows : SWEDISH CLASSIFICATION OF TRAIN AND MOVEMENT ACCIDENTS A. — Derailments : (1) Obstacle on line. (2) Defect in superstructure : (a) Breaking of rails. (b) Other defects. (3) Defect in rolling stock : (a) Breaking of axle. (b) Breaking of felloe. (c) Other defects. (4) Excessive speed. (5) Fault in shunting. (6) Defective state of turntable. (7) Other causes. B. — Collisions : (1) (2) (3) (4) (5) (6) (7) Defective signalling or inattention to signals. Parting of train (broken train). Train running into stations at too high a speed. Starting vehicles at wrong time. Faulty shunting. Vehicles side-tracked without properly closing line or other carelessness. Other causes. C. — Other Accidents : (1) Running into vehicles. (2) Fire on trains. (3) Locomotive boiler explosion. (4) Other accidents. In France train accidents are also classified by defects or failures of rolling stock or permanent way or by negligence, etc., of employees. In Norwegian statistics the classification of derailments and collisions is based either on acts or failures to act of employees or — 38 — defects of equipment or premises and on certain extraordinary events such as falls of earth or stone, avalanches, etc. Other railway working accidents are not further specified in respect of causes except for "fires in train". I n Belgian pre-war statistics three main subdivisions were given for derailments and collisions : defects of permanent way, defects of rolling stock, and accidents due to faulty execution of service. These were again subdivided either according to the nature of the defects or failures of equipment and structure as regards the two former groups, and according to acts or failures to act of employees as regards the third group. T H E CLASSIFICATION OF CASUALTIES With regard to the classification of casualties, a distinction must be made between casualties resulting from accidents arising in railway operation in the sense of disturbing events and casualties not resulting from such railway operation accidents. I t must be noted t h a t this Report is concerned with the risks of railwaymen only. Classifications applied to all persons killed or injured are therefore not considered here. (a) In many statistics casualties resulting from accidents in railway operation are classified first of all into the main groups of accidents. I n British statistics, for instance, casualties in train accidents are grouped much in the same way as these accidents themselves, though somewhat more summarily as regards the casualties in accidents to rolling stock and permanent way. I n the United States statistics the main groups of train accidents, and also the subdivisions of these groups, the general classification and the special classifications, are applied to casualties. Certain railway operation casualties, it will be remembered — namely, those resulting from events causing less than 150 dollars damage to property and injury or only injury to persons — are included among train service casualties. I n the statistics, however, in which railway operation accidents are not distinguished from personal events, casualties in derailments and collisions are often grouped separately, while casualties resulting from other railway operation accidents are given together with casualties not resulting from such accidents. This is done, for instance, in the German, Swedish, Swiss, French, and other statistics. The subdivisions of the classifications of accidents are not — 39 — usually applied to casualties, except, e.g., in the Bulgarian statistics. In most other countries all casualties — railway operation casualties and others — are separately classified in a scheme adapted to casualties not resulting from railway operation accidents. In Belgium, casualties in derailments and collisions are given separately from all other casualties. (b) Casualties not resulting from railway operation accidents — those not connected with disturbing events — are classified either by the special contributory circumstances, by the nature of the work or by the local circumstances in which they occur. In regard to movement casualties, groups based on the criterion "nature of the work in which the injured was engaged", include casualties while coupling or uncoupling, moving wagons, shunting (in the sense of the personal work and not in the sense of an operation). Groups combining casualties according to local circumstances include casualties while walking on the line, or getting on or off engines and cars. Finally, groups determined by the special circumstances resulting in injury include falls from trains, caught between cars, run over by trains, striking against obstacles, etc. The German classification, which the Swedish, Swiss, Norwegian and some other systems resemble, contained six groups based either on the nature of the work, carelessness or "local circumstances". Distinction is drawn between casualties resulting from : (1) (2) (3) (4) (5) (6) train accidents; carelessness in getting on or off cars in motion, or in cars, etc. ; shunting and moving cars, etc. ; coupling or uncoupling; being on line or passing line not a t proper time; other carelessness in service. In some countries — for instance, in Norway — certain groups are summarised under the heading "shunting accidents". In Great Britain, movement casualties are classified first by the operation during which they happen — shunting accidents and other accidents — and then subdivided in some detail by various criteria. Some groups, which indicate the nature of the work (e.g. attending to machinery), are co-ordinate with groups based on the criteria of the special contributory circumstances (e.g. being caught between vehicles), while others indicate the local circumstances in which the accident happened (walking or standing on line). — 40 — In the United States statistics, train service casualties are subdivided according to groups of causes. The same grouping, incidentally, is applied to train service accidents, of which only a few are disturbing events. Some of the groups are based on the criterion of the nature of the work (coupling of locomotives and cars, coupling of air or steam hose and safety chains, operating locomotives, operating hand brakes, operating switches), while others are based on the criterion of special contributory circumstances (e.g. coming in contact with fixed structures while on moving cars or locomotives ; struck or run over by cars or locomotives not classified otherwise), and one group indicates the local circumstances (getting on or off cars or locomotives). Finally, there is one group comprising level crossing accidents and casualties, which is mainly a group of railway operation accidents and casualties 1 . These groups of casualties are then divided into several hundred subgroups which specify the nature of the work, the special contributory circumstances, or the local circumstances. In Belgian statistics, movement and certain non-movement casualties constituting one group are subdivided according to a detailed classification which combines a grouping by occupation with a grouping by causes. Casualties connected with the movement of trains, etc., are always separately mentioned. In some statistics, therefore, non-movement casualties not resulting from railway operation accidents are combined with movement casualties and classified with them, as, for instance, in the United States and in Belgian statistics. In British statistics non-movement casualties are separately classified. The groups are based mainly on the criterion of special contributory circumstances, frequently combined with an indication of the place or the local circumstances. Some groups, however, refer to the nature of the work. In the United States statistics, the non-movement casualties which are termed "non-train casualties" comprise, in addition to non-movement casualties of railway workers 1 , casualties of employees not engaged in railway operations properly so-called which are similar to casualties in manufacturing industries or other services; the classification of non-train casualties is of a general industrial character and not specially related to railway risks. 1 Train service casualties include, as mentioned above, non-movement casualties connected with the operation of trains, cars or locomotives. A great part of the non-movement casualties of railway workers are thus included among train service casualties. — 41 — To conclude, it has been seen t h a t the underlying principles of the classifications are much the same in most countries. Specific groups, however, do not coincide sufficiently to allow of a satisfactory comparison. I t should not be difficult to secure agreement upon a uniform scheme if the general grouping into railway operation accidents and the resulting casualties on the one hand, and casualties in railway working not resulting from operation accidents on the other hand, and the corresponding definitions, were adopted. PROPOSED CLASSIFICATION I t would appear from the instances cited t h a t co-ordinated groups are frequently based on different criteria which may be an obstacle not only to comparison, but also to a clear demarcation. For each subdivision only one criterion ought to be applied. A tentative proposal for a uniform classification may be given. The scheme is the result of the analysis of the various classifications, and is based in the main on those criteria which have been found at the basis of most classifications. (1) Accidents : railway operation accidents might be grouped according to the nature of the disturbance (e.g. derailments, collisions) whereby movement and non-movement accidents might be distinguished. The main groups might be subdivided into accidents due t o defects of equipment or of premises or to the acts or failures to act of employees. A further subdivision according to the rolling stock involved and the place or local circumstances under which the accident occurred might be introduced. (2) Casualties : casualties resulting from railway operation accidents should be classified according to the same scheme as the accidents themselves and could be included in the same tables. Casualties not resulting from railway operation accidents might be tabulated as movement and non-movement casualties. I n order to ensure a clear demarcation of the groups and the greatest possible comparability, one criterion only should be applied in determining the main groups of movement and non-movement casualties. The nature of the work in which the injured was engaged does not appear to furnish the best criterion, as it is not always of interest — 42 — for preventive purposes. Moreover, a classification by occupations, which is altogether indispensable, will in many cases specify the nature of the work during which the accident occurred. The special contributory circumstances are more important from the point of view of prevention : if the classification by special circumstances is combined with t h a t of occupation, it will be shown how the risk inherent in the work actually resulted in injury. I t may, however, be necessary in order to obtain a clear idea of the origin of the accident to take into account in a subdivision either the railway operation, or the nature of the work or personal job. The workers in a given occupation may be engaged part of their time in particularly dangerous operations, e.g. technical processes such as shunting ; also the operation may require different jobs entailing unequal risks : coupling, for instance, may be especially dangerous. A co-ordinated subdivision by these two criteria (operation and nature of work) may therefore be desirable in order to bring out the inherent risk of the work. Finally, the casualty may happen not in any particular operation or job, but under certain local circumstances entailing special degrees of exposure. I n such cases this criterion might be applied in the subdivision. The following classification is based on the principles set out above. — 43 — I. — Accidents Arising Out of Railway Operation and the Resulting Casualties 1.

Scope State and Federal Railways only are covered; private railways are not covered. Accidents in the sense of this Report are not reported. Casualties reported are those which result from accidents which occurred through or in connection with the movement of rolling stock. All non-movement casualties (railway operation as well as other non-movement casualties) are thus excluded. Fatal and non-fatal casualties are, since 1924-1925, classified by the following groups : train accidents; accidents on line other than train-accidents; shunting accidents; proceeding to or from duty within the railway boundary. Up to 1923-1924, the classification was as follows : while in the execution of their d u t y ; proceeding to or from duty within the railway boundary. The former group was subdivided as follows : causes beyond own control ; contributory negligence ; solely own action or negligence. Casualties reported are those occurring in the working of the railway or on railway premises caAising the employee to be absent for at least one whole day from his ordinary work. AUSTRIA Summary statistics of railway accidents are published annually in the financial report of the Austrian Federal Railways {Geschäftsbericht der Unternehmung "Oesterr eichische Bundesbahnen"). These are much reduced as compared with the statistics published before the war in the report entitled Oesterreichische Eisenbahnstatistik (Austrian Railway Statistics). Formerly Austria also collaborated in the publication of the statistics of the "Verein 1 tion. Tables are only given in order to illustrate the chief types of classificaFigures are not comparable as between countries. — 50 — deutscher Eisenbahnverwaltungen". Only the more extensive pre-war statistics are described here 1 . Scope The statistics covered State and private railways, steam as well as electrical traction. Statistics for the main lines and local lines were more elaborate than those for minor railways (narrow-gauge lines) and cog railways. Statistics of accidents in ancillary undertakings, buildings for the administration, etc., classified by causes and nature of accidents, were compiled for administrative purposes, b u t were not published. Main and local lines. Accidents were classified according to the nature of the accidents and by causes. The accidents reported were derailments, collisions, trains running into vehicles, personal accidents, and miscellaneous. Each group was subdivided into train and shunting accidents. Personal events not resulting from disturbances of the operation were thus included. With the exception of boiler explosions, which were always reported, only movement accidents were reported, t h a t is, those arising by or during the movement of trains and rolling stock. Accidents in shunting were reported only if they had resulted in injury t o persons or material damage of more t h a n 1,000 gold kronen. Miscellaneous accidents comprised all other events arising in the course of the movement of rolling stock if they resulted in injury to persons. The classification by causes was as follows j defects in equipment, etc., defective execution of service (both groups being further subdivided), disregard of regulations, running at too high a speed, natural phenomena, misadventure, obstacles on line, criminal acts (Bahnfrevel), and other causes. Casualties. — Fatal casualties reported were those leading to death either immediately or within twenty-four hours after the accident occurred. Non-fatal casualties were registered if they resulted in incapacity to work for more than fourteen days. Casualties were classified as those due to own fault and those due to fault of third persons. Railway employees, in the sense of the statistics, were all persons working for the railway concerned, even if they were not directly remunerated by the railway administration concerned. Postal servants were comprised among "other persons". Statistics of accidents on minor railways were less elaborate than those for main lines and local lines. As a fatal casualty was considered any casualty leading to death, no period being fixed within which death had to ensue. A non-fatal casualty was one entailing incapacity to work for more than three days. Measures of Risk Accidents per 1,000,000 train km. (exclusive of personal events). Casualties per 1,000,000 train km. were calculated for casualties of all persons only, not for railwaymen separately. 1 Republication was planned for 1927. — 51 — BELGIUM The statistics of accidents on the railways are published in the form of a "Report on Operations" which appears annually in the reports presented to the Legislative Chambers by the Minister of Railways, etc.. entitled Chemin de fer et Service de l'Electricité. From 1920 the statistics furnished have been considerably reduced. The earlier and more detailed statistics are described here. Scope The statistics refer to State railways ; as regards private railways, only a few figures are given. Mention is made of events in railway transport properly so-called, and its maintenance, as well as in the upkeep of the permanent way, and of movement casualties in workshops. Statistics refer to the following accidents (disturbing events) : (a) Those which have caused serious material damage to trains, with resulting death or serious injury to passengers or railway employees, or which gave rise to an obstruction of the main roads for more t h a n an hour, and caused the suspension (suppression) or delay (détournement) of trains or displacement of passengers. (6) Those which have similar consequences but of less importance, or which might have caused a serious accident (detached cars, etc.). Accidents. — These are classified as collisions and derailments, and are therefore only accidents arising from train movements. The apportionment is made according to the place in which the accidents occurred. For collisions a distinction is, moreover, made according to whether they are head-on collisions, or collisions between trains running in the same direction, etc. The aggregate of accidents is subdivided as follows : (1) According to causes : (a) defects of permanent way ; (b) defects in rolling stock; (c) faulty execution of service. (2) According to whether they occur to passenger or to goods trains, light engines, etc. Each of these classifications is combined with that by place, etc. In addition, the number of collisions and derailments which caused injuries is indicated separately. Casualties. — Mention is made of the number of employees killed, injured or suffering from contusions. A fatal casualty is one entailing instantaneous death or subsequent death in consequence of the injury, before the Commission of Enquiry charged to examine the causes of the accident has terminated its report (i.e. two to three days at most after the accident). Casualties are classified in two main groups according to whether they resulted from accidents due to collisions and derailments of trains or from other causes. Cases falling within the first of these groups are apportioned according to the place of the accident and the nature of the collisions (see Accidents). — 52 — Other casualties happening to employees appear in a combined table. The cases referred to here include those arising in connection with the movement of engines and cars or while attending to apparatus (appareils) serving for the railway working (exploitation) and for the running of trains, such as points, signals, appliances for lighting of cars, for loading of goods, etc. The division into killed, injured and contused is made according to responsibility on one side, and according to the various duties in the course of which the victim of the accident was killed or injured and by causes on the other. Employees. — In the case of collisions and derailments, account is taken only of employees of the railway administration ; in the case of other accidents, there are included, in addition, employees of other administrations (postal servants, etc.), accidents to whom appear separately. Employees repairing the permanent way and buildings are counted among those of the railway administration. On the other hand, among persons not connected with the service, other than passengers, is found a group relating to casualties resulting from loading operations or assisting in shunting. BULGARIA The statistics of accidents on railways form part of the 'Statistics of Railways, etc.", published annually by the General Directorate of Railways and Ports, which forms part of the Ministry of Railways, Posts and Telegraphs. Scope Account is only taken of normal-gauge lines, and movement accidents occurring during railway transport, properly so called, and its maintenance. Accidents. — The classification resembles t h a t of the German statistics. Mention is made of derailments, collisions, and other accidents, apportioned in each case according to the kind of trains, the causes and the places of the accidents. The group "other accidents" only applies to accidents arising from movements of trains and rolling stock. I t is, however, to be observed t h a t the German statistics also include deaths and injuries which occur even if the train service is not disturbed ; on the contrary, the Bulgarian statistics keep exclusively to accidents in the sense of this Report, i.e. events disturbing the operation of the railway technically. Moreover, the Bulgarian statistics are more detailed than the German in the sense t h a t they combine the kind of trains and the places of accidents with the causes of the latter in the same table. Casualties. — Persons who die of their injuries within twentyfour hours are included in the deaths. Persons suffering from contusions are included among the injured. The victims of operating accidents due to train movements are grouped according to the causes (as for the accidents proper). In addition, figures are given for occupational risk during shunting, occupational risk in the train — 53 — service, and other causes. Here then, are cases not arising from railway operation accidents, but resulting directly from train movements or shunting operations. Lastly, the classification of casualties is made according to the various groups of the railway personnel. The personnel includes employees in the train service, those engaged in the maintenance of the permanent way and employees of the administration, but does not include postal servants. Measures of Risk Accidents : (a) Derailments 1 ( 1 ) per (6) Collisions J (2) per Casualties : (a) Killed 1 (1) per (2) per (6) Injured j (3) per 1,000,000 train km. 10,000,000 axle km. of all wagons. 1,000 members of the personnel. 1,000,000 train km. 10,000,000 axle km. of all wagons.. CANADA The Dominion Bureau of Statistics, Transportation Branch, publishes annually railway accident statistics in the Reports on Statistics of Steam Railways of Canada and Statistics of Electric Railways of Canada. The reports are made from returns made by the railways in accordance with the provisions of the Railway Act, 1919, and the Statistics Act, 1918, certified by the controllers of the railway companies or other officers. Up to 1921, railway statistics were published for steam and electric railways together. Accident statistics of electric railways are confined to a summary of the employees killed and injured. The following analysis refers to statistics of steam railways only. Scope Statistics cover all State and private railways and all kinds of gauges. Accidents in the sense of a material event causing death or injury to several persons are not reported. Casualties are reported as fatal if they result in death within twentj'-four hours. Non-fatal casualties to employees are only reported if preventing them from performing their service for more than three days in the aggregate during the ten days immediately following the event. Casualties, both fatal and non-fatal, are classified as "accidents resulting from the movement of trains" and "accidents resulting from other causes than the movement of trains". The former group (movement casualties) are subdivided by causes (coupling and uncoupling, collisions, derailments, parting of trains, locomotives and cars breaking down, falling from trains or cars, jumping on or off, struck by trains, etc., overhead obstructions, other — 54 — causes); and also by classes of employees (trainmen, trackmen, switch tenders, etc.; stationmen, shopmen, telegraph employees, other employees). Casualties not resulting from the movement of trains are only classified by classes of employees. The classification differs from t h a t above quoted and runs as follows : trackmen, stationmen, shopmen, other employees, postal clerks, etc. Finally, accidents at highway grade crossings are given separately for trainmen and passengers in common. Employees in the sense of the statistics are all persons employed by the railway companies, including postal and telegraph clerks, and freight handlers. CZECHOSLOVAKIA The Statistika Ceskoslovenskych Drah, published annually by t h e Ministry of Railways, contains accident statistics. Scope The statistics include State railways and private railways, and cover exclusively railway transport service properly so-called and its maintenance. Accidents. — A distinction is made between collisions and derailments on the one side, and "other extraordinary events" on the other. Collisions, grouped according to the place in which they happened, are classified as collisions of trains, collisions of vehicles with trains; then the cases are classified according to their cause. Derailments are also classified by place and cause. The "other extraordinary events" include irregularities in the movement of trains which did not entail injury or material damage, e.g. cases due t o the following causes : passing signals, running on wrong line, collisions on same track, etc. All other extraordinary events are grouped separately from those just mentioned, whether they are accidents in train operating (movement), such as trains running into vehicles at level crossings, or accidents which do not arise from train movements, such as fire in buildings; criminal acts against the railways; damage by flood; breaking of axles, wheels and tyres; or damage preventing the subsequent running of trains. Casualties. — Deaths of and injuries to railway employees are classified according to the nature of the work done by the persons injured and while walking on line. A special column, however, relates to casualties resulting from railway operation accidents. Statistics cover trainmen and train service employees. Figures concerning deaths and injuries of postal servants in the course of d u t y are furnished in other special columns. There is no official definition of "fatal casualty"; in practice, however, fatal casualties are those resulting in death within four weeks from the date of the accident or personal event. Measures of Risk (1) Accidents and extraordinary occurrences : (a) per 100 km. of line worked; (b) per 1,000,000 axle km. — 55 — (2) Deaths train (3) Deaths train and injuries of railway employees : per 1,000,000 km. and injuries of postal servants : per 1,000,000 km. FRANCE Before the war French railway accident statistics were published annually by the Ministry of Public Works aud of Transport, Railway Department (Ministère des Travaux publics et des Transports, Direction des Chemins de fer), in the report entitled Statistique des Chemins de fer. These statistics were republished in 1928. Since 1924, the Director of the Railways Technical Operation Inspectorate in the Ministry of Public Works (Contrôle de l'exploitation technique des chemins de fer au Ministère des Travaux publics) publishes an "Annual Report on the general position with regard to accidents on the great French railways" (Rapport annuel sur la situation générale des grands réseaux de chemins de fer français au regard des accidents) in the two reports Annales des Mines and Annales des Ponts et Chaussées. ^'ANNALES DES M I N E S " AND " A N N A L E S DES PONTS ET CHAUSSÉES" Scope The statistics cover the great railway systems of general interest only, whether State or private railways. Accidents. — Only accidents in railway transport properly so called are registered, exclusive of accidents in workshops or stores (dépôts). Serious cases only are reported, viz. : (1) Train accidents resulting in death of persons or injury to persons of whatever severity. (2) Other accidents arising from railway operations properly so called, if they resulted in injury entailing incapacity to work of more than twenty days. Accidents are classified as follows : (1) Train accidents resulting in death or injury to persons. (2) Accidents at level crossings. (3) Other accidents arising from the operation of the railway, such as train accidents involving serious damage to rolling stock, etc. (matériel), coupling accidents, shunting accidents, switching accidents, accidents while loading or unloading wagons, and other personal events entailing incapacity to work of more than twenty days, etc. To sum up, statistics do not cover all accidents resulting in injury, but include also personal events not connected with or resulting from a disturbance of train operations. In a combined table, train accidents are classified by their nature into five groups and by seventeen main groups of causes. The five former groups are as follows : — o e - il) Side way collisions. (2) Collisions, shocks, and trains or parts of trains running into each other during shunting (tamponnements en manœuvre). (3) Collisions of trains running in the same direction (tamponnements par l'arrière;, rattrapage de trains). (4) Derailments. (5) Miscellaneous (trains running away or going adrift) (emballements de trains ou dérives). The classification by causes groups accidents according to fault of railway servants and according to failure or defects of material. Accidents at level crossings are given separately for guarded crossings and crossings without gates (barrières) on the one hand, and are grouped as accidents to persons on foot and to vehicles on the other. Casualties. — As noted above, all casualties arising from train accidents and all other casualties entailing incapacity to work for more than twenty days are reported '. Fatal and non-fatal casualties are classified by the same groups as accidents, and casualties resulting from train accidents are also grouped according to the nature and causes of the accidents. Both classifications, however, apply to all persons injured only, not to railway servants separately. Casualties not resulting from disturbances of the operation of trains are included without further distinction in the group "other railway operation accidents". Railway servants in the sense of the statistics include trainmen and train service employees, but not office and workshop employees, nor porters. As casualties of railway servants are counted only those happening to servants on duty. Measures of Risk Rates of fatal and non-fatal casualties of railwaymen per thousand railwaymen are calculated. An attempt is made in the Annales to compare the results of the French statistics with the corresponding statistics for the United States, Great Britain and Germany. " STATISTIQUE DES CHEMINS D E EER " Scope These statistics include the State Railways and private companies, both main and secondary lines. The accidents are subdivided into : derailments, collisions, and miscellaneous accidents. I n each of these groups the accidents are classified according to the place at which they occurred. The casualties are classified as follows : casualties in train accidents, in accidents of railway working other than train accidents, and casualties from imprudence or misadventure. Each of these categories is grouped under killed and injured. 1 A casualty is classified as "fatal" if death ensued immediately, or at most a few days after the accident. — 57 — Measures of Risk Casualties from train accidents : Killed per 1,000,000 train km. Injured per 1.000,000 train km.

GERMANY Railway accident statistics are published annually by the Ministry of Transport of the Reich in the report entitled Statistik der im Betriebe befindlichen Eisenbahnen Deutschlands. — 58 — Scope Statistics relate to all standard-gauge railways of the State (federal) as well as the private lines. Both steam and electric railwaj's are included. Only "railway accidents and casualties" so called are comprised, i.e. cases only which occurred by or during the movement of trains. All non-movement cases are consequently excluded. The scope of the statistics was greatly reduced in 1922. As to accidents, all derailments and collisions involving trains are reported, whether personal or material damage of property resulted or not. Collisions and derailments of parts of trains are only reported if either personal injury or damage of more than 1,000 gold marks results. Explosions of locomotive boilers are reported in any case ; fires in trains, if personal injury or damage to railway property or to goods of more than 1,000 gold marks resulted. Trains running into vehicles are reported where persons are injured, animals killed or street vehicles damaged. All other events are only reported if persons are injured. Casualties reported are all fatal casualties resulting in death or leading to death within twenty-four hours and all non-fatal casualties disabling the worker for more than fourteen days or leading to death after twenty-four hours. Data and Up to collisions the place Sources 1921, accidents were classified by causes; derailments and moreover according to the kind of trains involved and where they occurred — at stations or on the line. Casualties are classified : (a) By categories of persons, viz. (1) railway employees and railway workers on duty; (2) postal, telegraph, police, and other employees on duty; (3) other persons, including railway employees and workers not on duty. (6) Casualties of railway employees and railway workers on duty were separately classified by causes u p to 1921. The classification was different from t h a t of accidents (see table III). Casualties are now classified as those in derailments and collisions (combined) and "others". All workers, whether working for the railway company itself or for a contractor, provided they are injured during their work by the working of the railway, are considered as "railway workers". Workers in workshops are altogether excluded. Measures of Bisk Up t o 1921, the following rates were calculated : (1) Accidents per 100 km. of track. (2) Accidents per 1,000,000 car axle km. — 59 — (3) Casualties of railway employees and workers per 1,000,000 train km. : (a) fatal, (b) non-fatal. (4) Casualties of railway employees and workers per 1,000,000 car axle km. : (a) fatal, (6) non-fatal. (5) Casualties of all persons (passengers, railway employees and workers, postal, telegraph, etc., employees and other persons including railway employees and workers not on duty) per 1,000,000 train km. and per 1,000,000 car axle km. These rates have now been discontinued and only accident rates per 1,000,000 car axle km. are calculated.

A Report to the Minister of Transport upon Accidents that have Occurred on the Railways of Great Britain summarises and analyses this information. Scope Accident statistics cover all public railways in the United Kingdom up to 1922, and in Great Britain only since 1922, including London Tubes and other electric railways. Statistics cover all accidents and casualties on "railway premises", viz. "stations, permanent way, goods yards and all other premises used for working the railway, but not factories, workshops, buildings used exclusively for warehousing goods, repairing sheds, hotels and other similar premises". Both movement and nonmovement accidents are therefore included. As to accidents, statistics include : (1) Any accident attended with loss of life or personal injury. (2) Any collision where one train is a passenger train. (3) Any passenger train or part of a passenger train leaving the rails. (4) Any accident of a kind not comprised in the foregoing description, but which is of such a kind as to have caused or to be likely to cause loss of life or personal injury and which may be specified in t h a t behalf by any Order to be made from time to time by the Board of Trade. As to casualties, fatal casualties are those in which the worker is killed or so severely injured "as to die at any subsequent date after the accident, but prior to the date of this report". All nonfatal casualties disabling the worker at least one whole day from doing his ordinary work, are reported 1. Casualties to servants of railway contractors are included. Data and Methods of Computation Accidents have to be reported, under section 6 of the Railway Regulation Act, 1871, by the companies to the Ministry of Transport. Accidents are only reported for the group "train accidents", which are those involving trains, rolling stock or permanent way. They are grouped as : (1) accidents to trains, and (2) accidents to or failure of rolling stock or permanent way, and are classified by "causes" and the kind of trains involved. Casualties are grouped as those resulting from : (a) "train accidents", (6) "movement accidents", and (c) "non-movement accidents". Each group is classified by causes and railway company (see tables IV, V, and VI). 1 Casualties of passengers or other persons have to be reported, however alight the injuries may be. 5 — 62 — Train casualties, movement casualties, and non-movement casualties to railway servants are, moreover, classified according to the occupation of the worker involved and according to the nature and location of the injury. The railway employees whose railway casualties are included comprise all persons employed by the railway companies, including those employed on the Manchester Ship Canal, and not simply workers on "railway premises" as defined above. The Reports give summary figures for several years and periods. A classification by so called "primary causes" is made for movement casualties.

Formerly, Hungary also collaborated in the publication of the statistics of the "Verein deutscher Eisenbahnverwaltungen". Scope Statistics cover State railways as well as private railways. Main lines and local lines are included. Only accidents in railway transport properly so called are reported. Workshops, therefore, are altogether excluded from the statistics, and accidents in work on new buildings, etc., are included only if the accident occurred in connection with the movement of a train or parts of a train. — 68 — Accidents. — Only accidents in railway working are taken into account. They are classified by the nature of the accident, viz. derailments, head-on and side-on collisions and miscellaneous accidents. The latter group contains also accidents not arising in connection with movement of trains or rolling stock, the group being made up as follows : running into vehicles, fire in trains, boiler explosions and other events. The last group comprises also personal events not connected with disturbances of train operations, such as persons being run over, etc. Casualties. — Only casualties, fatal and non-fatal, resulting from accidents reported, are recorded. A casualty is classified as fatal if death results before the obligatory report has been submitted, or if death will doubtless ensue in a very short time. Railwaymen. —• Only employees engaged on trains and in train service are included. Measures of Risk The number of employees per (a) fatal and (b) non-fatal casualty is calculated. INDIA Railway accident statistics are published annually by the Railway Department of the Government of India in the Report by the Railway Board on Indian Railways. Since 1924-1925 statistics are much the same as those published for the United Kingdom. The main groups are as follows : (1) Accidents to trains, rolling stock, permanent way, etc. (2) Accidents caused by movements of trains and railway vehicles, exclusive of train accidents. (3) Accidents on railway premises in which the movement of trains, vehicles, etc., was not concerned. The first group, therefore, comprises railway operation accidents and casualties, while the second and third group contain casualties not resulting from railway operation accidents. These are grouped into movement and non-movement casualties. All three groups are classified by detailed catises. Movement casualties of railway servants on Class I railways are moreover classified according to acts, or failures to act, of railway servants, or according to failures or defects of rolling stock, etc. The classification reads as follows : Misadventure and accidental; want of caution or misconduct by the injured person; want of caution or breach of rules, etc., of other servants; defective systems of working; dangerous places and conditions of work; want of rules or systems of working; defective apparatus, appliances, etc., or want of safeguards, etc. Percentages of all movement casualties by these causes are moreover calculated. No measures of risk are given. — 67 — ITALY The State Railways administration furnishes material for two different sets of statistics. One is published by the Ministry of Transport under the title Relazione per l'anno finanziario (Report for the Financial Year). The other, emanating from the Central Statistical Office, is entitled Statistica dell'esercizio (Statistics for the Civil Year), of which a summary is given in the Statistical Annual. Scope The statistics of accidents are limited to railway transport properly so called and its maintenance. Accidents (Relazione). — These are classified under : derailments, collisions and miscellaneous accidents; collisions and derailments are subdivided in their turn according to whether they occur on the line or in stations. In the case of collisions, a further distinction is made according to whether they occur at a guarded level crossing or an unguarded one. Collisions include encountering and overthrowing obstacles. The miscellaneous accidents comprise, apart from those due to shunting and to outbreak of fire (along the line and in stations), personal events without damage to property, i.e. falls from trains, outrages and suicides. The classification adopted in the second publication {Statistica) is much more detailed. Principal groups : causes and effects of accidents, the second group referring evidently to the nature of the accident. The "causes" are divided into defects in locomotives, wagons and permanent way; faults in train and shunting service, and various causes such as negligence, etc., outrages, atmospheric influences, and unknown causes. The "effects" are classified as material damage to rolling stock or fixed property, obstruction of the permanent way, encountering and overthrowing obstacles, fires (in trains and in stations), derailments, collisions, falls from trains. Each of these groups is subdivided in its turn into several categories. Accidents reported are thus mainly train movement accidents, but certain cases not arising from train movements are included, such as accidents due to railway operations, properly so called, and also a number of personal cases not arising from railway operations. Derailments and collisions during shunting operations are only mentioned if they result in : (1) a fatality or a non-fatal casualty; (2) important material damage ; (3) an interruption of the service of at least thirty minutes in the case of passenger trains, and of at least an hour for goods trains, independently of delays due to other causes. Casualties (Relazione). — Deaths of, or injuries to, employees are grouped according to the causes of the death or injury : accidents, carelessness of the personnel, criminal acts (attentali e aggressioni), — 68 — other causes. Moreover, insurance statistics of casualties are published, containing cases of injury and the days of sickness. Cases are grouped according to severity. (Statistica.) Injuries which result in death within twentyfour hours are counted as deaths. An injury is counted as such if it is not healed within five days. The classification of casualties in the Statistica is the same as t h a t in the Relazione. Casualties resulting from accidents (causa degli accidenti) are given only in so far as the accident is a "cause arising directly from duty" (causa diretta del servizio). Employees (Statistica). — Employees who are killed or injured other than in the course of duty are counted in the statistics as persons foreign to the service. Statistics cover trainmen and train service employees (on line and in station), as well as office employees and permanent way men and inspectors. Measures of Risk - (Statistica.) Individual cases (killed and injured) in groups according to causes are classified : per 100 km. of line; per 100,000 train km.; per 100,000 locomotive km. ; per 100,000 axle km.

Scope The statistics refer to the State Railways and private lines. Accidents. — These are mentioned in so far as they take place on railways and in connection with train traction. The figures seem therefore to extend to accidents following from the movement of trains and those happening apart from the movement of trains. — 69 — NETHERLANDS The Statistical Annual furnishes statistics of railway accidents and indicates the reports of the "Bikstoezicht op de Spoorwegen" as its source. These reports have been stopped since 1921. Before the war the Netherlands were included in the statistics of the "Verein deutscher Eisenbahn Verwaltungen". Scope The statistics cover the State Eailways and other public lines, main as well as local lines. They refer to railway transport service properly so called, but not to workshops, building of new lines, etc. Only accidents and casualties resulting from the movement of trains and rolling stock are included. Accidents. — Accidents are classified as derailments, collisions and other accidents, comprising yard-shunting accidents resulting in bodily injury, serious material damage or serious disturbances of service. Casualties (individual cases). — Accidents to employees are classified as follows : "fault of service", "own fault", and "during shunting in stations", and are grouped in killed and injured. Fatal casualties are those resulting in death before the report of the enquiry into the causes of the accident is made. NORWAY Railway accident statistics are reported in the yearbook Norges Jernbaner, published by the "Hovedstryret for Statsbanene" in the series entitled Norges O/fisielle Statistihk. They are for the years beginning 1 July and ending 30 June. Scope The statistics cover all accidents and casualties arising from operations connected with railways, and the conception does not only extend to movement and non-movement accidents on railway premises properly so called, as in Great Britain, b u t also to annexed premises and operations, as shunting in gravel pits and work yards, work in gravel pits, work in shops, cleaning of material, loading and unloading goods in warehouses, etc. Accidents and casualties are then divided into two groups : (1) Accidents and casualties in the running of trains, i.e. in railway transport properly so called, including train service and shunting service 1. (2) Casualties in other railway work. This division does not entirely correspond with the division into movement and non-movement risks, as the first group only includes accidents and the resulting casualties occurring in the running of trains engaged in ordinary traffic or additional trains, and the 1 "Under den egentlige jernbanedrift." — 70 — accidents in the shunting of such trains. The second group (other railway work) therefore comprises casualties occurring in the running of work trains, trains engaged in ballasting, driving snow ploughs, etc., as well as casualties in the maintenance of the lines and the like, which may also be movement casualties. Accidents are grouped into "accidents to trains" and "other accidents", covering together the "accidents in railway transport properly so called" of group (1). Accidents to trains are subdivided into derailments, collisions, and miscellaneous accidents. "Accidents to trains" include only such accidents "as have occasioned or by their nature might have occasioned danger to persons or material, and accordingly every derailment, breaking of axles, etc., but not accidents which only caused delay, such as boiler-tube explosions . . . etc.", except where they result in material damage or personal injury. Damage of less than 10 kroner is not taken into consideration. Serious damage is damage of at least one-tenth of the cost of the material. "Other (than train) accidents" comprise accidents in train and shunting service not included among train accidents, if they result in personal injury or, as regards shunting accidents, in material damage. Casualties are classified as fatal and non-fatal, a casualty being fatal if it results in death within twenty-four hours, while non-fatal casualties include only those in which the injury required medical treatment. Casualties in the "running of trains" (railway transport properly so called) and in other work are kept apart. Data and Methods of Computation Train accidents are classified by causes and place. Other (than train) accidents in railway transport properly so called are grouped as "accidents in the running of trains involving persons" and "accidents in shunting service". Casualties in railway transport properly so called, i.e. in train and shunting service, which are those resulting from the accidents of group (1), are given separately for railway servants in train and shunting service, which include only persons engaged in running or shunting trains and employees working in stations or on the line in connection with such operations on the one hand, and "servants on d u t y " on the other hand, the latter comprising railway employees "travelling or being otherwise on the railway in connection with service but not engaged in running or shunting trains", such as persons engaged in inspection, if killed or injured in or near a train or during shunting operations. The former group (casualties of railway employees in train service and shunting service) is classified by causes (see table). Employees not on duty and customs officials travelling free, if injured in railway transport accidents, are included among "other persons and employees not on duty". Casualties happening in other railway work, that is, outside railway transport properly so called, are given for all railway — 71 — servants and workers on duty together, and are not furti;er subdivided. Measures of Risk Casualties of railwaymen in train and shunting service, per 1,000,000 train km. : (a) fatal, (6) non-fatal.

Scope The statistics are established separately for normal-gauge and for narrow-gauge lines, and include accidents and casualties due to movement of trains and rolling stock. \ — 72 — Accidents. — These are classified under : collisions, derailments, miscellaneous accidents, and subdivided in each case into accidents happening along the line and in stations. Casualties are divided as such into : collisions, derailments, collisions daring shunting, and miscellaneous accidents. Information is also furnished concerning the amount of property damaged. Measures of Risk Accidents : (a) On the line : per km. of line. (6) In stations : per station. Casualties : per 0 0 0 0 0 0 train km (6) £"urtd 1 i' ' - Property damaged : per 1,000,000 train km. PORTUGAL The Statistical Annual publishes statistics of accidents on railways. Scope The statistics cover State and private railways. Accidents. — Movement accidents only are reported, while casualties include also those of workers in workshops, repairing sheds, etc. Accidents are classified as derailments, collisions and miscellaneous accidents. The derailments and collisions include those of wagons or carsengaged in shunting. "Miscellaneous accidents" comprise all accidents arising through the movement of trains, whether railway operation accidents as defined in this Report or personal events involving injury to passengers, railway servants or other persons only (accidents while ascending or descending moving trains, falling from trains, hit by wagon doors, run over or caught by trains in stations, at level crossings or on lines, etc.). Casualties. — Fatal and non-fatal casualties reported are those resulting from the accidents registered, t h a t is, casualties in railway operation movement accidents and others occurring during the movement of trains. They comprise therefore all movement casualties. Moreover, casualties in workshops and repairing sheds are reported separately. Casualties are tabulated in three groups : (1) Casualties in workshops and repairing sheds (Nos Officinas) ; (2) Casualties (resulting from railway operation accidents) in other services; (3) Persons injured during the running of trains (on or by trains in motion). The two latter groups therefore comprise the casualties resulting from the accidents reported in the three groups above-mentioned and no additional cases. — 73 — The workers whose casualties are reported are therefore all railway workers whether in the train service, working on permanent way, etc., on the one hand, and all workers in workshops and repairing sheds, such as metal workers, smiths, carpenters, painters, plumbers, etc., on the other. RUMANIA Rumania was formerly included in the statistics of the "Verein deutscher EisenbahnVerwaltungen". The Rumanian Statistical Year Book furnishes summary statistics of accidents on railways. Since 1925, more detailed statistics have been published. Scope The statistics include the State Railways, which have acquired most of the private lines. Accidents. — In the number of accidents are also included cases of death and injury not arising from an event causing an interruption in the service (disturbance of operation). Accidents are classified, first of all in three kinds of collisions — collisions with stationary objects, head-on collisions, side-on collisions — and in derailments. These cases seem to represent the accidents arising from the nature of railway work, as they are added together. Mention is also made of other kinds of accidents, which are distinguished as : wagons moved by wind, breaking of trains, breaking of axles, unforeseen non-stops, unforeseen stops, trains running into miscellaneous objects, falls from trains, fires, covering of snow, other accidents, floods. These accidents are combined : (1) with the place a t which they happen, either along the line, or in a station, and in the case of the latter (a) on the arrival and departure of the train; (b) during shunting; (2) with the causes, according to whether they arise from defects in the line or in rolling stock, irregularity in operating, causes foreign to the railways (atmospheric accidents, force majeure, own fault, criminal acts), unknown causes. Casualties. — Casualties are classified by the nature of the accidents from which they result (same classification as for accidents) and according to whether they are the results of faults in railway working or other causes. The two classifications are combined. Each of these two groups is subdivided into deaths and injuries. SWEDEN Railway statistics in Sweden are published by the administration of the Swedish Government Railways in the annual reports Statens Järnvägar (State Railways) and Allmän Järnvägsstatistik (General Railway Statistics, containing figures for the different railway systems of the country, with a French translation of the table headings). Both reports are published in the series Sveriges offideila Statistik (Swedish Official Statistics). — 74 — Scope Swedish statistics cover only "movement" accidents and casualties, i.e. those occurring in connection with the running of trains and shunting. Not included, therefore, are casualties occurring in repairing sheds, in coupling or uncoupling cars at rest, in getting on or off vehicles at rest, in handling turntables, signals, etc., while loading or unloading, etc., where no movement of rolling stock takes place. Accidents. — Accidents are classified as derailments, collisions, and other accidents. All derailments involving locomotives or cars intended for train service are reported under this heading, but not those of bogies, trollies, etc., and single cars derailed b u t replaced on rail without serious damage. In shunting service, only derailments which cause serious damage to persons or material are reported. Collisions are such between vehicles intended for train service only; collisions between such vehicles and bogies, trollies, etc., or other objects are therefore not included. Collisions in shunting service are reported only where they result in serious personal or material damage. "Other accidents" include all locomotive boiler explosions; trains running into road vehicles, if serious injury results, animals are killed or vehicles destroyed ; fire in trains if resulting in serious damage to persons or material and all other accidents resulting in serious personal injury : derailments and collisions not reported under these headings; running over persons; accidents while stepping on or off moving vehicles, and others resulting in injury. Serious material damage means damage of at least 1,000 kronor. Casualties reported are those resulting from movement accidents, provided they result in death or injury incapacitating for work for at least fourteen days. Data and Methods of Calculation Accidents and casualties have to be reported by the district officers of the State Railways and by the managers of the private railway companies. Accidents, i.e. the three groups collisions, derailments and "other accidents", are further subdivided by causes as well as by place (on road or at station), and "class" of service (train and shunting service). The resulting casualties are given for all persons involved, not for railwaymen separately. The classification of accidents by causes is given in the text (page 37). Casualties are classified separately by causes. The classification is given in table I X . The railwaymen covered by the statistics include not only the ordinary and temporary staff employed by the railway, but all workers carrying out any work for the railway, whether directly paid by the railway or by contractors. — 75 — Measures of Risk (1) Accident rates per 100 km. line for all accidents. (2) Accidents per 10,000,000 car (axle) km., for all accidents. (3) Casualties per 1,000 railwaymen (exclusive of workers in shops, etc.) : (a) fatal, (6) non-fatal. (4) Casualties per 1,000,000 train km. : (a) fatal, (6) non-fatal. (5) Casualties per 10,000,000 car (axle) km. : (a) fatal, (6) non-fatal.

(2) The financial report (Geschäftsbericht) of the Federal Council (Bundesrat) contains accident statistics. (3) The Tableaux statistiques, annexes au rapport de gestion de la Direction générale pour l'année . . . , published by the Federal Post and Railway Department, contain some statistics on accidents on the Federal Railways. Scope The first report refers, as far as the subject of our Report is concerned, to all railways, standard gauge and narrow gauge, and cog railways —• federal as well as private lines, whether with «lectric or steam traction, being included. The financial report combines accident statistics for railways as above defined, as well as tramways and rope railways. The statistics cover movement accidents and casualties, i.e. those connected with the movement of trains or cars, as well as casualties due to electricity (electric current). Accidents reported are those arising in the running of trains properly so called. As derailments are registered all derailments of passenger trains; derailments of other trains and trains engaged in shunting are registered only if they result in serious injury to persons or serious damage. Collisions registered are all collisions of passenger trains with other trains or single cars, and those collisions of other than passenger trains and of trains engaged in shunting which result in serious injury to persons or serious damage. "Other accidents" are all events involving trains or single cars resulting in serious injury to persons or serious damage, including personal events arising in connection with the movement of trains or cars, such as accidents while crossing the line, etc., and in addition those due to contact with electric wiring (Fahrleitungen). Casualties. — The casualties registered are those arising in connection with the movement of trains or due to electric current. F a t a l casualties reported are those injuries resulting in death immediately or within twenty-four hours after the occurrence of the accident. Non-fatal casualties are casualties entailing incapacity to work for more than fourteen days (up to 1925, more than six days). Data and Methods of Computation Schweizerische Eisenbahnstatistik. — Accidents are classified as derailments, collisions and "other accidents" : the former two groups — 77 — are further subdivided as those "in stations" and those "on the line ". "Other accidents" are distinguished as those resulting in injury to persons and other accidents. Serious damage means damage of more than 1,000 francs. Casualties of railwaymen are classified as casualties in derailments and collisions, on the one hand, and casualties in other accidents, on the other. The railway employees covered are all persons employed by the railway administration. Measures of Bisk (1) Casualties of railway employees per 100,000 locomotive km.: (a) fatal, (b) non-fatal. (2) Casualties of railway employees per 1,000,000 axle km. : (a) fatal, (b) non-fatal. Geschäftsbericht des Bundesrates. — Accidents are classified as above. Moreover, derailments are classified as under : (1) Defects in the permanent way {Bahnanlage). (2) Obstacles on line. (3) Wrong setting of points. (4) Defects in rolling stock. (5) Other and unknown causes. Collisions are subdivided as follows : (1) Defective orders, communication, or wrong acts of staff. (2) Defective signalling or setting of points. (3) Disregard of regulations in shunting and carelessness of trainmen. (4) Wrong placement of vehicles. (5) Other causes. Moreover, accidents to moving trains, and in shunting, are distinguished. Casualties are classified as above. Moreover, casualties from accidents other than derailments and collisions are subdivided by causes as follows : (1) Collision with motor-cars or street vehicles. (2) Slipping on moving cars, etc. (3) Getting on or off moving cars, etc. (4) Walking on or crossing line. (5) Carelessness in moving train and during shunting movements. (6) Misadventure in shunting service. (7) While coupling or uncoupling moving cars, etc. (8) Forbidden or wrongly executed shunting movements. (9) Opening and closing of wagon doors. (10) Injury to eyes by (flying) particles, etc. (11) Injury due to electricity in service. (12) Other causes. 6 — 78 — In the "Statistical Tables" of the Federal Railways, we find as to accidents, that derailments and collisions are classified by the kind of trains involved, and by secondary causes. For casualties, the following rates are calculated : (1) Rates per 1,000,000 train km. (2) Rates per 1,000,000 locomotive km. (3) Rates per 1,000,000 axle (car) km. (4) Rate per 100 of total staff engaged in railway service properly so called. UNITED STATES Statistics of accidents on steam railways are published annually by the Interstate Commerce Commission, Bureau of Statistics, in the Accident Bulletin, and monthly in a Summary of Accidents Reported by Steam Railways. Moreover, the United States Department of Labour publishes summary statistics of railway accidents — together with those of other industries — in the Statistics of Industrial Accidents, which appears irregularly. A report entitled Statistics of Railways, 1906-1916, published by the Bureau of Railway Economics in 1918, contained a summary of accidents. Statistics of accidents on electric railways are registered in the report of the Department of Commerce, Bureau of the Census, Electric Railways, which contains very summary accident statistics only. In the following résumé reference is only made to the Accident Bulletin as providing the main regular reports and sources of information summarised elsewhere. Scope Accident statistics refer to all steam railways of the United States. The more detailed data, however, are reported for Class I railroads only, viz. those having annual operating revenues above 1,000,000 dollars. As to accidents, the report in the Bulletin covers all accidents arising from the operation of a railway, in connection with the operation or movement of trains, cars and locomotives, which result either : (1) in damage to railway property in excess of 150 dollars; (2) in death or injury to persons as defined. As to casualties, a fatal casualty is one resulting in death within twenty-four hours after the accident occurred. Non-fatal casualties therefore include casualties leading to death later than twenty-four hours after the accident and those casualties which entail injury to the employee disabling for more t h a n three days within the ten days following the accident. The report publishes all fatal and reportable non-fatal casualties resulting from the "operation of the railway", not only those arising in connection with the operation or movement of trains, cars or locomotives. The "operation of the railway" covers all operations performed "under — 79 — the supervision of the carrier by its employees". Statistics include, therefore, accidents and casualties on tracks, in stations, depots, freight houses, warehouses, shops, coaling stations, wharves and ferries as well as accidents in the maintenance of equipments, roadway, track, buildings, etc., and the construction of "additions, betterments, and new lines, if this construction is performed by the carriers' regular forces of employees ordinarily engaged in the construction, operation or maintenance of existing lines". Statistics, therefore, cover movement and non-movement casualties, the latter including also those of workers not directly engaged in the working of the railway. Data and Methods of Computation, Accidents have to be reported by the railway companies under the Accident Reports Act of 1910 to the Interstate Commerce Commission. Accidents. — Accidents are grouped as train and train service accidents : (1) Train accidents are accidents with or without casualties, arising in connection with the operation or movement of trains, locomotives or cars and resulting in damage to equipment of other railway property in excess of 150 dollars. (2) Train service accidents are those arising in connection with the operation or movement of trains, locomotives or cars and resulting in reportable casualties to persons, but not in damage in excess of 150 dollars. Train accidents are classified by the nature of the accident (see table X), and the main groups of this classification are subdivided by negligence of employees, defects in or failure of equipment, defects in or improper maintenance of way and structures, and miscellaneous causes, as well as by kind of train involved, all three classifications being combined. Each of the groups of causes enumerated above is subdivided by very detailed specific causes. Train accidents, by nature and causes, are given for districts. Train service accidents are classified by groups of causes. Highway grade crossing accidents are classified by the kind of protection afforded at crossing and the kind of vehicles involved. Train and train service accidents are specified by kinds of trains involved. Casualties are grouped as casualties in train accidents, train service accidents, and as non-train casualties. Non-train casualties are those not caused directly by the operation or movement of trains, locomotives or cars, resulting in reportable injuries or death to persons. Casualties in train accidents are grouped by the nature of the accidents and by the same causes as train accidents. The classifications are given for trainmen and other employees separately. The detailed classifications by specific causes are also given for trainmen and other employees, but not again specified by the nature of the accident (collision, etc.). — 80 — Train casualties are, moreover, grouped by the nature of the injury received, by the nature of the accident and by certain occupations of trainmen, in a combined table. Train service casualties are classified like train service accidents for trainmen and other employees separately. The detailed specific classifications are subdivided by those occupations of trainmen which are mainly involved in the specified group of casualties. Train service casualties are also classified by nature of injury in combination with the main groups of causes and certain occupations. Non-train casualties are grouped by causes. All casualties, train, train service and non-train casualties, are, for each group separately, classified in greatest detail by occupations, in combination with main causes. Main groups of occupations are moreover classified by roads, for train and train service casualties combined, and for non-train casualties, by districts. The number of employees in service is taken from the monthly reports of the Service and Compensation of Steam Railway Employees, as is the number of man-hours worked. (a) The number of employees is based on monthly statements (middle of month), counting the employees usually on duty on the day of the count as well as employees under pay on vacation or sick leave and "extra" men in train and engine service. In the classification of occupations and groups of occupations, employees whose duties are such as to make them capable of being included in two or more "reporting divisions" are included in t h a t division indicated by the greater part of their time during the month. (6) The man-hours are reported in the same way (they include normal hours and overtime hours). In computing the man-hours for each occupation, however, the time of each employee is distributed among the occupations he may be alternatively engaged in, each occupation being credited with the hours the worker actually spends in t h a t work. Measures of Bisk (1) Casualties per 1,000,000 locomotive miles; in all train and train service accidents : (a) fatal, (6) non-fatal. (2) Casualties per 1,000,000 man-hours (all causes) by occupations : (a) fatal, (6) non-fatal. (3) Casualties per 1,000,000 man-hours (all causes) by roads and occupational groups : (a) fatal, (6) non-fatal. — 81 — (4) Number of employees per employee : (a) killed, (b) injured. (5) Number of trainmen per trainman : (a) killed, (b) injured. (6) Trainmen killed per 1,000 trainmen in train and train service accidents by : (a) yard ] (6) road freight [ service.
