The train involved in Wednesday’s Stonehaven rail tragedy struck a landslip and derailed, rail investigators have revealed.
Three people died after the Aberdeen to Glasgow Queen Street service crashed south of Stonehaven.
Six people were injured, with two of them remaining in hospital in stable condition.
The leading power car and third passenger carriage fell from the railway down a wooded embankment after striking a section of bridge parapet which was destroyed.
As published in the Press and Journal, a report published by the Rail Accident Investigation Bureau (RAIB) revealed that the 6.38am Scotrail service from Aberdeen to Glasgow was forced to turn back after Stonehaven due to bad weather conditions.
How the crash unfolded
- The train left Aberdeen at 6.38am, and departed Stonehaven on time shortly after.
- After heading southbound the train was stopped near Carmount after a radio message from the signaller after a train heading north reported a landslip blocking the line between Carmont and Laurencekirk.
- The train was instructed to return to Aberdeen
- After travelling 1.4miles back towards Stonehaven the train struck a landslip.
- As the line curved to the right, the train continued in a straight line for around 90 metres until it hit a section of the bridge parapet, which was destroyed.
- The leading power car continued over the bridge and down a wooded embankment along with the third passenger carriage.
- The first passenger carriage came to rest on its roof, having rotated to be at right angles to the track.
- The second passenger carriage also overturned onto its roof and came to rest on the first carriage.
- The fourth passenger carriage remained upright and attached to the rear power car; it also came to rest on the first carriage.
