Two trains have collided in Wales and the emergency services are attending, police have said.

The incident happened near Llanbrynmair, between Shrewsbury and Machynlleth, at about 7.30pm on Monday.

It is not yet known if there have been any injuries.

A British Transport Police spokesperson said officers were called to the line near Llanbrynmair after reports of "a low-speed train collision involving two trains".

"Paramedics, fire and rescue, and Dyfed Powys police are all in attendance and the incident is ongoing."

A joint statement from Network Rail and Transport for Wales said the incident involved the 6.31pm service from Shrewsbury to Aberystwyth and the 7.09pm service from Machynlleth to Shrewsbury.

Network Rail said the "operational incident" meant lines were closed and trains may be cancelled or revised.

Wales's first minister, Eluned Morgan, wrote on X: "My thoughts are with all those involved in the rail incident in Powys earlier this evening.

"I would like to thank the emergency services for their response and have asked to be kept informed of any developments throughout the night."
