Welcome to the RAIB website

The Rail Accident Investigation Branch (RAIB) is the independent railway accident investigation organisation for the UK. It investigates railway accidents and incidents on the UK's railways to improve safety, not to establish blame.

This website forms the RAIB's primary channel for sharing the findings from its investigations, as well as providing the railway industry and general public with a means of finding out about the RAIB.

RAIB's role
Train tracks

Our purpose for investigating an accident or incident is to improve the safety of the railways, and to prevent further accidents from occurring.

We achieve this by identifying the causes of accidents and other aspects that made the outcome worse.

Our investigations are entirely independent and are focused solely on safety improvement - we do not apportion blame or liability, nor do we enforce law or carry out prosecutions.

Carolyn Griffiths, Chief Inspector of Rail Accidents
