Railway Accident and Incident Investigation

Evidence, Causation and Safer Operations

Protect | Preserve | Establish | Analyse | Learn

What happened is only the beginning. A credible investigation must establish why it happened, which controls failed and what must change to prevent it happening again.

Railway Accident and Incident Investigation: Evidence, Causation and Safer Operations is a comprehensive 308-page guide for railway managers, investigators, station leaders, safety professionals and operational staff.

Written by experienced railway operational leader and Station Incident Officer Robert Porter, the book combines structured investigation practice with the realities of live railway environments.

It begins with the immediate response: protecting life, controlling further risk, raising notifications, preserving the scene and identifying evidence that may disappear within minutes or hours.

A dedicated evidence section explains the distinction between physical, documentary, digital, witness and perishable evidence. Readers are shown how to maintain an evidence register, protect original files, preserve metadata, document transfers and maintain a defensible chain of custody.

Slips, trips and falls receive detailed treatment. The book examines underfoot conditions, surface materials, contamination, drainage, weather, lighting, footwear, handrails, crowding, distraction, cleaning, inspections and maintenance history.

Steps, stairs, escalators and platform–train interface incidents are explored through measured rise, going, gradients, gaps, train stopping positions, door thresholds, stepping distances and passenger movement.

Photography guidance covers:

Overall, approach, relationship and close-up photographs

Camera position and perspective

Scales and evidence markers

Lighting and reflective wet surfaces

Photograph logs and timestamps

Original files and controlled working copies

CCTV chapters address urgent preservation, camera ownership, time offsets, blind spots, native export, retention, audit information, lawful processing and the dangers of estimating movement speed without calibrated evidence.

The book explains the relevant UK framework, including RIDDOR, ROGS, the Railways (Accident Investigation and Reporting) Regulations, RAIB, ORR, BTP and parallel company investigations. Because individual train operating companies use different controlled procedures, readers are given a TOC procedure-mapping framework rather than a fictional universal process.

Human factors and interview chapters cover free recall, open questions, witness welfare, memory limitations, contradictory evidence, fatigue, workload, situational awareness and fair accountability.

Analysis methods include timelines, immediate and underlying causes, systemic factors, barrier analysis, change analysis, alternative hypotheses and confidence statements.

The book also includes:

A first-hour evidence card

Perishable-evidence register

Photographic evidence log

CCTV preservation request

Slip, trip and fall scene checklist

Witness interview plan

Causal-analysis framework

Recommendation quality check

TOC procedure map

Welfare follow-up plan
