A passenger train was derailed in a tunnel when it collided with a block of ice in West Yorkshire.
The Network Rail train was carrying 47 passengers when it was derailed just before 1.47am on Tuesday in the Summit tunnel at Walsden on the Yorkshire-Lancashire border outside Todmorden.
No-one was injured.
The ice is thought to have fallen from the tunnel roof or an air vent.
Passengers evacuated to Todmorden Sports Centre. Five fire crews and a fire service rescue team from Batley were called to the scene.
