RAIB Interim report: Collision between passenger trains near Talerddig, Powys, 21 October 2024

The collision took place on Network Rail’s Cambrian line to the west of the passing loop located at Talerddig, Powys (figure 1). One passenger died and four other people were seriously injured. Neither train derailed in the collision, although significant damage was caused to the leading vehicles of both trains.

From each direction, the railway approaching Talerddig passing loop consists of a single line, with the loop allowing trains to pass each other. Train 1J25, travelling west, was due to stop in the loop to allow eastbound train 1S71 to pass it. Train 1J25 was braking as it approached and passed through the loop. Despite this it was unable to stop within the loop as intended. The train subsequently exited the loop, while still braking, and re-entered the single line, heading towards train 1S71. Train 1J25 travelled approximately 1,080 metres beyond its intended stopping point, before colliding with train 1S71.

At the time of the collision, train 1J25 was travelling at approximately 39 km/h (24 mph), while train 1S71 was travelling in the opposite direction at approximately 11 km/h (6 mph).

This interim report is based on the evidence gathered and analysed to date. Topics relevant to the accident are likely to be covered in more detail within the final report.

A final report will be published by RAIB on completion of its investigation.
