Report 08/2026: Collision between two passenger trains near Talerddig

Collision between two passenger trains near Talerddig, Powys, 21 October 2024.

At around 19:26 on Monday 21 October 2024, train reporting number 1J25, the 18:31 service from Shrewsbury to Aberystwyth, collided with train 1S71, the 19:09 Machynlleth to Shrewsbury service. The collision took place near Talerddig, Powys. Both train services were operated by Transport for Wales Rail Limited (TfWRL).

The trains were operating on Network Rail’s Cambrian lines. This is predominantly single track, with passing loops provided at intervals to allow trains travelling in opposite directions to pass each other. Train 1J25 had been approaching the loop at Talerddig, with an intended stopping position within the loop, so that train 1S71 could pass it. However, train 1J25 did not stop as intended, continuing through the passing loop and into the single line section on which train 1S71 was approaching.

The head-on collision occurred while train 1J25 was travelling at approximately 39 km/h (24 mph) and train 1S71 was travelling at approximately 11 km/h (6 mph) in the opposite direction. At the point where the collision occurred, train 1J25 had travelled around 1,080 metres beyond its intended stopping position.

A passenger travelling on train 1J25 suffered fatal injuries as a consequence of the collision. Three people on this train were also seriously injured, including the train’s guard, and 18 other people received minor injuries. The driver of train 1S71 suffered serious injuries, and the remaining five people on this train all suffered minor injuries.

Neither train derailed, but extensive damage was caused to both trains. Damage was also caused to railway infrastructure in Talerddig loop. The railway remained closed until 28 October 2024.

RAIB’s investigation found that the accident was caused by train 1J25 passing its authorised stopping position and entering the single line beyond, which was occupied by the approaching train 1S71.
