The tragic Bedford train crash that killed one train driver and injured 89 during the evening peak period on Friday raises similar questions about safety layers to two other collisions in mid-Wales in 2024 and Salisbury in 2021.
Each involved a breakdown in systems designed to maintain safe separation or prevent conflicting movements between trains, where braking appears to have been too late or insufficient to prevent impact.
The Bedford accident occurred on a recently upgraded main line and early reports indicate one of the trains was stationary or stopped on the line when it was struck from behind by another train.
The mid-Wales crash at Talerddig, Powys, in October 2024 that killed one passenger and seriously injured four others, involved a head-on collision on the same section of a single-track rural line. At least one driver was unable to stop in time.
The 2021 accident in Salisbury near a junction happened when one of the trains involved passed a signal at a dangerous speed and entered the path of another service, and emergency braking applied was insufficient to prevent the crash.
