As we were going to press yesterday (Thursday), an investigation was continuing into a train crash in West Carmarthenshire.

Shortly before 10 am on Monday, a heavy goods vehicle carrying hay was involved in a collision with the 9.10 am Milford Haven to Manchester Piccadilly Arriva Trains Wales service at Henllan railway crossing.

Five passengers on the train were taken to hospital suffering from minor injuries, while later in the day, British Transport Police, who were leading the investigation, confirmed a local man had been arrested on suspicion of endangering safety.

A British Transport Police (BTP) spokesman said: "BTP officers were called to the railway line at Henllan Amgoed, Whitland, after a report that a train had struck a lorry towing a trailer over Llanboidy crossing.

"The incident was reported to BTP at 9.55 am. Colleagues from Dyfed-Powys Police, the Welsh Ambulance Service and Mid and West Wales Fire and Rescue Service also attended.

"The train remained upright and on the tracks following the collision.

"It is believed there were around 50 to 60 passengers on the train.

"In total, seven people were treated for minor injuries, with five being taken to hospital."

BTP's sector commander for Wales, Chief Inspector Sandra England, said: "Our investigation is continuing into the cause of the collision, including piecing together exactly how the vehicle came to be on the tracks at the time.

"As part of that investigation, the driver of the vehicle, a 48-year-old man from Llanboidy, has been arrested on suspicion of endangering safety.

"He has been taken to a police station in Haverfordwest, where he is assisting my officers with their enquiries.

"Measures are now in place to remove the vehicle from the tracks, but in the meantime, the road on both sides of the crossing remains closed.

"Officers from the Rail Accident Investigation Branch (RAIB) are currently on route to the site and will begin their investigation on arrival."

Fire appliances from Whitland, Carmarthen, Crymych, and Haverfordwest attended the incident.

Station manager Justin Lewis said: "A total of 59 people were assisted off the train. Crews assisted Welsh Ambulance Service personnel in treating passengers, and five casualties were conveyed to hospital via ambulance. Oxygen therapy was administered by fire crews, and fire crews made the train safe.
