A passenger train collided with debris washed onto the track following heavy rainfall, and the subsequent derailment resulted in the death of three people, injuries to the six other people in the train and catastrophic damage.
The interim report, which is based on evidence gathered and analysed to date, includes RAIB’s preliminary findings. It contains a lot of detail on the circumstances that led up to the accident, the accident itself and its aftermath. Diagrams and photographs are used to describe exactly what happened so that readers can visualise how events unfolded, and how the various coaches of the train ended up in the positions they did.
Finally, the report summarises the areas of ongoing investigation work that are being carried out by RAIB. It refers to some safety actions already taken by the rail industry. It does not contain any RAIB recommendations for how safety could be improved – these will be contained in the final report that will be published by RAIB on completion of its investigation.
RAIB’s investigation is running independently of the joint investigation instructed by the Lord Advocate to be carried out by Police Scotland, British Transport Police and by the railway industry’s regulator, the Office of Rail and Road (ORR). However, all investigating agencies, and the industry, are co-operating fully with each other.
