A stretch of the A470 in Powys is still closed as investigators are on the scene following a fatal train crash by Llanbrynmair.

Following a collision between two Transport for Wales trains at Talerddig on Monday, October 21, the road near the site remains closed to all vehicles as investigators from the Rail Accident Investigation Branch (RAIB) and British Transport Police try to get to the bottom of why the accident happened.

A Google Maps view of the A470 on Wednesday, October 23, shows that the stretch of road between Glanwymyn and Plas Llysyn remains closed, adding that it is closed until midnight, while the RAIB said their investigation is “in its very early stages”. Traffic monitoring service Inrix and Traffic Wales have both confirmed the ongoing closure.

A man in his 60s died, four other people were seriously injured and 11 more sustained injuries requiring hospital treatment.

Some have stated that the investigation could take “several days”, leading to a prolonged closure of both the road and track while the search for evidence is carried out.

Montgomeryshire MP Steve Witherden said shortly after the crash: “Both the track and the A470 remain closed. The Rail Accident Investigation Branch will need to attend and inspect the site before Network Rail is able to check that the track is safe to reopen.

“I have heard this could take several days. Whilst the people involved and their families will want answers as soon as possible it is important that we do not speculate and we let the investigation carry out its work.”

The RAIB said: “RAIB’s initial inspection of the track on approach to the point of collision found evidence that wheel/rail adhesion was relatively low, suggesting that the train may have entered into wheel slide when braking.

“This will be an area of ongoing investigation.

“Our investigation is in its very early stages and an additional update will be available in the coming days once RAIB has gathered and analysed further evidence.”
