Real Definitions (Railway Board Letter No. 2000/Safety(A&R)/19/20 dt.31.10.2000)

This real letter superseded Board Letter No. 88/Safety(A&R)/29/8 dated 18.4.1980 and letters of 10.8.2000 & 17.10.2000, re-defining accidents as follows.

Real Injury Classification & Threshold Value

Real Grievous injuries follow the definition in Section 320 of the Indian Penal Code (45 of 1860): (A) emasculation; (B) permanent privation of sight of either eye; (C) permanent privation of hearing of either ear; (D) privation of any member or joint; (E) destruction or permanent impairing of the powers of any member or joint; (F) fracture or dislocation of a bone or tooth; (G) any hurt endangering life, or causing severe bodily pain, or incapacity to follow ordinary pursuits, for real 20 days. Real Simple injuries: incapacitate the injured person from their customary vocation for real 48 hours after the accident (or, for a railway servant, prevent return to work for real 48 hours).

Real Threshold Value has 2 parts: (a) loss to Railway property fixed at real Rs. ONE LAKH; OR (b) interruption to communication (partial or total) equal to or more than the real hours specified per gauge/route type.

Real Interruption TypeReal BG-A,B,C or D Spl. (hrs)Real BG-D,E Spl or MG-Q,R (hrs)Real BG-E, MG-S or Ng route (hrs)
Total346
Total + Partial6812

Duration of interruption is defined as the time from the accident until the first train starts on line-clear from the adjacent station for movement over the affected line.

Real Classification of Accidents — 5 Real Heads

Real HeadReal Scope & Real Class Codes
(i) Train AccidentsInvolves a train. Real 2 sub-types: (a) Consequential — serious repercussion (loss of life/injury/property loss/traffic interruption): Collision (A-1 to A-4), Fire (B-1 to B-4), Level Crossing (C-1 to C-4), Derailment (D-1 to D-4), Miscellaneous (E-1). (b) Other train accidents — remaining codes B-5/B-6, C-5 to C-8, D-5, E-2.
(ii) Yard AccidentsAccidents in a yard NOT involving a train — codes A-5, B-7, D-6.
(iii) Indicative AccidentsReal term for serious potential hazards, NOT actual accidents — SPAD, averted collision, breach of block rule — codes F, G, H.
(iv) Equipment FailuresFailure of loco/rolling stock, permanent way, OHE, signalling & telecom equipment — codes J, K, L, M.
(v) Unusual IncidentsLaw-and-order-related cases not resulting in train accidents — codes N, P, Q, R.

Real Full A–R Classification Codes

Real common pattern across classes A-E: within each class, the FIRST codes (e.g. A-1/A-2, B-1/B-2, C-1/C-2, D-1/D-2) cover the MAJOR/consequential case — split by whether the train carries passengers — requiring loss of life/grievous hurt AND/OR property damage exceeding real Rs. 25,00,000 AND/OR communication interruption of at least real 24 hours. The NEXT codes cover the same scenario NOT meeting that major threshold, and the LAST code(s) in each class cover yard/non-train occurrences of that same accident type.

Real ClassReal Codes & Meaning

Real Reportable Train Accidents & Serious Accident Definition

Real Reportable Train Accidents fall under Section 113 of the Railways Act, 1989: (a) any accident with loss of human life or grievous hurt; (b) any collision between trains, one of which carries passengers; (c) derailment of any passenger-carrying train or part of it; (d) accidents with loss of human life in a passenger train involving train-wrecking/attempted wrecking, running over obstructions placed on the line, passengers falling out, fires, grievous hurt per IPC, or serious property damage exceeding real Rs. 25 LAKH which might reasonably have been expected even if it didn't actually occur — and also landslides/breaches/floods causing interruption of an important through line of communication for at least real 24 hours.

Real Serious Accident: an accident to a passenger-carrying train with loss of life or grievous hurt to a passenger, or serious property damage exceeding real Rs. 25,00,000, or any other accident the Chief Commissioner/Commissioner of Railway Safety opines requires a CRS inquiry. Real 3 EXCLUSIONS: (a) trespassers run over/injured/killed through own carelessness, or passengers injured/killed through own carelessness; (b) railway servants or valid pass/ticket holders killed/grievously injured while travelling OUTSIDE the rolling stock of a passenger train (footboard, roof, buffer — excluding vestibule interiors), or run over at an LC or elsewhere on track; (c) level-crossing accidents where no passenger/railway servant is killed/grievously hurt, unless the CCRS/CRS opines an inquiry is needed.

Real Reporting & Level of Enquiry

Real telephone-advice-on-reporting rule: to Railway Board — for all consequential train accidents, yard accidents with serious traffic repercussion above threshold, and land slides/breaches/OHE breakdown above threshold (plus monthly statement in prescribed proforma for all categories). To Zonal Railway — for all train accidents (not just consequential), plus the same yard/land-slide/OHE conditions (plus monthly statement).

Real Level of EnquiryReal Who Inquires
Serious accidentsCommissioner of Railway Safety (CRS); if CRS/CCRS unavailable, a JA Grade Inquiry Committee
Other consequential train accidents (except unmanned LC accidents)Committee of JA grade officers (or Branch officers in their absence)
Consequential Unmanned Level Crossing AccidentsCommittee of Junior Scale Officers
All other train accidentsCommittee of Senior Scale or Junior Scale Officers as decided by respective DRMs
Yard accidentsCommittee of Senior Supervisors
Indicative AccidentsCommittee of Junior Scale Officers
Equipment failuresSenior Supervisors/Supervisors of respective departments

Real rule: a Safety Officer must be one of the members of every Departmental Accident Inquiry Committee — if a Safety Officer of the same grade isn't available in the Division, one grade below may be nominated. Real accounting rules: accidents to trains are accounted for by the Railway with site jurisdiction; engine failures by the Railway owning the engine; statistical returns (cumulative to month-end) must reach the Board's office no later than the real 7th day of the next month; each accident is shown only ONCE — if it falls in more than one category, it's treated under the HIGHER category. Fire statistics include physical fire/smoke emission causing death/injury/damage of real Rs. 5000 or above. Details/statistics for Unusual-incident categories N, P, Q are maintained by the Security (RPF) Branch.

Real Action at Site & Sabotage Procedure

Real Disaster Management — Golden Hour

Disaster management involves intelligent/meticulous planning and prompt response. Real planning points: relief equipment at strategic points; nearby medical-facility information available in detail; ART/ARME kept ready with full essentials. Real prompt-response points: earliest accident-detail relay to control; medical personnel/volunteer help requested; quick redressal to injured; preserve clues; on/off-duty staff should rise to the occasion; a logbook records all activity incl. passenger names; civil authorities requested if needed; information centres opened at site and convenient places; restoration time communicated to the public; restoration not started without police clearance in suspected sabotage; incorrect information not given in haste.

🎯
Exam Focus — Real 'Golden Hour' Concept
Rush to the site by the quickest possible means — the FIRST ONE HOUR is called the 'Golden Hour', during which, if a medical relief team arrives, many precious lives can be saved in fatal accidents.

Real Accident Inquiries — Objectives & Classification

Rules for CRS inquiry guidance are in the real 'Statutory Investigation into Railway Accidents Rules, 1998' (notified by the then Ministry of Tourism & Civil Aviation vide G.S.R.587 dated 09.04.73, amended vide GSR 20 dt.17.10.80 & GSR No.704 dt.09.07.85). Real history: a uniform inquiry code for State Railways was first prescribed in real 1879, but had no statutory backing until the Indian Railways Act, 1890 (since replaced by the Railways Act, 1989).

An inquiry is necessary if: (1) the accident is 'Serious' per Section 113; (2) a passenger train is involved; (3) there's reason to believe Railway staff are responsible (prima facie or per police report); (4) the system involved is suspected deficient/defective; (5) the cause isn't clear; (6) for any special reason the GM/CSO/DRM considers an inquiry necessary; (7) the CRS asks the GM for a comprehensive report — this last inquiry may be dispensed with if it's already handled by CRS/Commission of Inquiry, there's no reasonable doubt about the cause, or a Railway department accepts responsibility.

Real 10 Objectives of Accident Inquiries
  • 1. Establish the cause beyond reasonable doubt. 2. Fix responsibility for failures/commissions/omissions/rule violations, enabling follow-up punitive action. 3. Assess adequacy/practicability of the system. 4. Assess adequacy of existing preventive measures/rules/instructions and their implementation. 5. Ascertain skills, knowledge and effective functioning. 6. Examine safety aspects of installation/working/maintenance. 7. Review the Railway system's response in rendering adequate/prompt relief and rescue. 8. Recommend alterations/modifications to layout, signalling etc. 9. Be a useful tool to minimize accidents. 10. Help compile accident-related statistics at various levels. Real note: the PRIMARY objective is identifying system efficiency/weakness and improving safety performance — awarding punishment to responsible staff takes NEXT priority.

Real 2 levels of inquiry: (1) NON-RAILWAY — Commission of Inquiry, Commission of Railway Safety (CRS), Magisterial inquiry, Police investigation. (2) RAILWAY — Major Joint Inquiry, Minor Joint Inquiry, Departmental Inquiry.

Real Non-Railway Inquiry Levels

Real Railway Inquiries — Major/Minor Joint & Departmental

Real Conducting Railway Inquiries — Procedure

🎯
Exam Focus — Real Inquiry Time Schedules & Disciplinary Deadlines
Real CRS-level time schedule: D+2 preliminary report by DRM to GM (serious accidents); D+3 holding of inquiry; D+5 detailed report by DRM to GM for Railway Board; D+10 inquiry proceedings forwarded by DRM to GM; D+27 finalisation of inquiry report and submission to accepting authority. Real Joint-Inquiry time schedule differs by level: SAG level — commencement D+4, submission for acceptance D+8, submission of accepted findings to competent authority D+10. JAG-and-below level — commencement D+3, submission for acceptance D+8, submission of accepted findings D+10. Real disciplinary-action deadlines: must be completed within real 60 days for a MINOR penalty, real 90 days for a MAJOR penalty.

The Safety Directorate of the Railway Board compiles accident statistics annually — per Zonal Railway, and cause-wise/responsibility-wise/equipment-failure-wise — including casualties, injuries, property-damage loss, and traffic detention/disruption. Each finalised inquiry's details are posted in the 'Accidents Register' at the concerned station/workplace, perused by inspecting officials to identify accident trends and accident-prone employees for remedial action. A sample accident-inquiry report format is enclosed as Annexure 'A'.
