Notes to editors

  • Images must be credited to RAIB unless otherwise stated. 
  • The Rail Accident Investigation Branch (RAIB) is responsible for conducting independent investigations into railway accidents in the UK. The purpose of its investigations is to improve safety, by establishing the causes of accidents and making recommendations, to reduce the likelihood of similar occurrences in the future or to mitigate their consequences. RAIB is not a prosecuting body; its investigations are focused solely on safety improvement and do not apportion blame or liability.
  • RAIB’s investigation is running independently of the investigation being undertaken by the railway industry’s regulator, the Office of Rail and Road (ORR). However, all investigating agencies, and the rail industry, are co-operating fully with each other.
