Emergency services say three people on the Milford Haven to Manchester service suffered minor injuries near Whitland at 09:50 GMT. Oxygen was given to one and another was treated for a head wound before they were taken to hospital. Arriva Trains Wales (ATW) said up to 60 passengers were on the service. Replacement buses are running between Carmarthen and Milford Haven, with all train services on the south Wales line west of Carmarthen being stopped. ATW said the train involved was the 0910 Milford Haven to Manchester service. It was not derailed in the incident and BBC Wales reporter Aled Scourfield, close to the scene, said the lorry was still upright. The incident happened at the Llanboidy level crossing on a minor road near a spot called Crossing Cottage. British Transport Police (BTP), Dyfed-Powys Police and paramedics were at the scene between Whitland and Henllan Amgoed. Map of incident scene The Welsh Ambulance Service said two ambulances and the Wales Air Ambulance were sent to the scene. Crews treated three people at scene for minor injuries before taking them to West Wales general hospital in Carmarthen for further treatment. Mid and West Wales Fire and Rescue said it appeared the crossing barrier came down on the lorry before the train collided with it. A BTP spokesman said: \"An investigation is underway into the cause of the collision, including how the vehicle came to be on the tracks, and the Rail Accident Investigation Branch (RAIB) has been notified.\" Engineers and rail managers have gone to assess the damage and help passengers.
