The trains involved were the 18:31 Transport for Wales service from Shrewsbury to Aberystwyth and the 19:09 service from Machynlleth to Shrewsbury.

Leaves on the track are being investigated as a potential cause, as Network Rail spends millions clearing foliage during autumn due to its slippery effect.

Passengers are advised to check their travel plans with National Rail Enquiries due to service disruptions following the incident.

Initial investigations by the Rail Accident Investigation Branch (RAIB) suggest that low adhesion between the train wheels and rails may have contributed to the crash.

The Cambrian Line will remain closed while investigations continue, with updates expected from the RAIB soon.

Among the injured, four individuals sustained serious injuries, while 11 others required hospital treatment.

Railway engineer Gareth Dennis indicated that modern safety systems should prevent collisions, and investigations will focus on potential causes such as low adhesion or failures in the European Train Control System (ETCS).

A tragic train collision occurred on the Cambrian Line at Llanbrynmair, Powys, Wales, around 7:30 PM, resulting in the death of a man in his 60s and injuring 15 others.

The deceased's family has been informed and is receiving support from specialist officers.

Transport Secretary Louise Haigh emphasized the priority of railway safety and the need to understand the incident to prevent future occurrences.

Network Rail and Transport for Wales expressed gratitude to emergency services for their swift response and are collaborating with agencies to investigate the incident.

This incident follows the Stonehaven crash in 2020, which highlighted vulnerabilities in the rail infrastructure and prompted calls for increased investment in safety.
