The death toll in the Selby rail crash has risen to 13, with a further 30 people seriously injured.
More than 100 firefighters are at the scene, battling to rescue those still trapped inside the wreckage.
Hospitals in Leeds and Doncaster are on full alert at present, and are handling the dozens of casualties ferried from the scene.
All nine carriages of the 4.45am GNER Newcastle-King's Cross intercity train - the main service from the North-East to London - derailed at Great Heck near Selby after a Land Rover and trailer skidded off a railway bridge on the M62 motorway and onto the track.
A goods train was also involved in the head-on collision, but police say they are still not certain which train was first on the scene.
