ACCIDENT MANUAL CHAPTER - III CLASSIFICATION OF ACCIDENTS Accident: For the purpose of Railway working, accident is an occurrence in the course of working of Railway which does or may affect the safety of the Railway, its engine, rolling stock, permanent way and works, fixed installations, passengers or servant or which affect the safety of others or which does or may cause delay to train or loss to the Railway. For statistical purposes accident has been classified in to categories from “A’ to “R” excluding “I” and “O”. 3.01. Classification of Accidents : Accidents are classified under following heads:- I. Train Accidents. II. Yard Accidents. III. Indicative Accidents. IV. Equipment failures. V. Unusual incidents. 3.02 Train Accident:- Train accidents is an accident that involves a train. Train Accidents are further divided as: (a) Consequential train accidents (b) Other train accidents. (a) Consequential train accidents : Include train accidents having serious repercussion in terms of loss of human life, human injury, loss to Railway property or interruption to Rail traffic. Train accident under following classification will be termed as consequential train accidents:- Collision : All cases under category A-1 to A-4. Fire : All cases under category B-1 to B-4. Level crossing : All cases under category C-1 to C-4. Derailment : All cases under category D-1 to D-4. Miscellaneous : All cases under category E-1. (b) Other train accidents :- All other accidents which are not covered under the definition of consequential train accidents are to be treated as “other Train accidents”. These include accidents under categories B-5, B-6, C-5 to C-8, D-5 and E-2. 3.03 Yard accidents :- All accidents that take place in a yard and does not involve a train are termed as Yard Accidents. These include accidents falling under category A-5, B-7, C-9 and D-6 . 3.04 Indicative Accidents :- In real term they are not accidents but are serious potential hazards and include all cases of train passing signal at danger, averted collision, breach of block rule coming under classification F, G and H . 3.05 Equipment failures: these includes all failure of Railway equipment i.e. failure of locomotives, rolling stock, permanent way, over head wire, signalling, and telecommunication equipment etc. and include cases falling under classification J, K, L & M. 3.06 Unusual incidents: These include cases related to law and order but not resulting in train accidents and other incidents under classification N,P,Q and R. 3.07 Detailed classification of accidents: Class ‘A’ – Collisions A-1 Collision involving a train carrying passengers, resulting in (i) loss of human life and/or grievous hurt and/or (ii) damage to Railway property of the value exceeding Rs.25,00,000 and/or (iii) interruption of any important through line of communication for at least 24 hours.
