This devastating incident took place in 2001 when a sleep-deprived driver swerved off the M62 at just before a bridge over the East Cost Main Line in Great Heck, near Selby. His Land Rover finished on the track and he was unable to move the car. A passenger train hit his car and was derailed. This caused it to be deflected into the path of a freight train.
This dreadful accident caused the deaths of several people and many more to be seriously injured.
