A major incident has halted trains in part of West Yorkshire.

Rail services were suspended tonight after an emergency on the tracks on the key trans-pennine route which runs from Leeds and Huddersfield  towards Stalybridge and Manchester.

Reports suggest that a train may have struck a pedestrian at Slaithwaite, in the Colne Valley area of Kirklees.

Trans-Pennine Express has tweeted: "Due to the emergency services dealing with an incident on the line at Slaithwaite, all services are currently suspended between Stalybridge and Huddersfield. More information to follow."

A picture has emerged on social media of a stationary train on Slaithwaite viaduct.

One Facebook poster said an air ambulance had landed nearby.

Another said there had been an incident at Slaithwaite railway station "involving a person and a train."

The poster said the person was treated at the scene and conveyed to hospital.

The condition of the injured person remains unclear.
