Initial crash findings released

Preliminary findings from the Rail Accident Investigation Branch (RAIB) suggest that low wheel-rail adhesion may have been a key factor in the recent train collision at Talerddig, Powys.

Inspectors noted evidence that the train may have experienced "wheel slide when braking," which could have contributed to the collision between two Transport for Wales services on 21 October 2024.

RAIB inspectors were dispatched to the scene shortly after the incident and have been working closely with British Transport Police, the Office of Rail and Road, and railway companies to secure evidence.

"RAIB’s initial inspection of the track on approach to the point of collision found evidence that wheel/rail adhesion was relatively low," the agency stated. This potential loss of traction will be a key focus of their ongoing investigation.

In addition to examining the possibility of wheel slide, the investigation will also look at other critical factors such as train condition, signalling systems, and track quality. The RAIB noted, "This will include examining the condition of the train and downloading its ‘black box’ data recorder, inspecting the track, analysing data from railway signalling and radio systems, and interviewing witnesses."

While the investigation is still in its early stages, RAIB has emphasized that further updates will be provided in the coming days as more evidence is collected and analyzed.

It is expected that the Cambrian Line will remain closed tomorrow.
