Rail Accident Investigation Branch
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.
The RAIB is concerned with the investigation of accidents and incidents on:
- The national railway networks in Great Britain and Northern Ireland;
- The Channel Tunnel (in co-operation with its equivalent operation in France);
- The London and Glasgow Underground systems and other metro systems;
- Tramways;
- Heritage railways (including narrow-gauge systems over 350mm gauge); and
- Cable-hauled systems of 1km or longer.
The Rail Accident Investigation Branch (RAIB) carries out the investigation into rail accidents and incidents without apportioning blame or liability with a view to enabling lessons to be learned, improving safety on railways and preventing similar accidents and incidents. The RAIB’s investigations are entirely independent and are focused solely on safety improvement. RAIB make recommendations addressed to ORR which has the role of National Safety Authority. ORR consider the recommendations and pass them on to dutyholders who are required to take them into consideration and where appropriate act upon them.
