Britain’s worst rail crash of the 21st century saw 10 people dead including the drivers of two trains at Great Heck near Selby, North Yorkshire, on this day in 2001.

One man’s tiredness was to blame.

Builder Gary Hart, who was driving down the westbound carriageway of the M62, had been up much of the previous night talking on the phone to a woman he had met on the internet when he fell asleep at the wheel at just after 6am.

His Land Rover and its trailer smashed through crash barriers at the edge of the M62, and the car rolled 377 ft down an embankment onto the southbound tracks.

Hart dialled 999, having woken up due to the crash.

Forty seconds seconds later he yelled, “There’s a train coming!” then said that the train had, “Gone straight through my Land Rover.”

The InterCity 225 going south was partially derailed but still travelling at 88 mph: it hit a 1,800-tonne coal train going north at 54 mph, according to Health and Safety Executive estimates.

Carriages of a freight train lie derailed at the side of the track after an accident near Selby, North Yorkshire which claimed thirteen lives. A further 70 people were injured when a high-speed GNER passenger train hit a runaway car and then collided with the freight train  * ...  which was carrying more than 1,000 tonnes of coal. The scene of devastation was on the East Coast main line near Selby in North Yorkshire.  28/02/01: The GNER engine 91023, which was involved in the rail crash in Yorkshire, in which 13 people died is the same one which was involved in the crash at Hatfield in October 2000.  The engine was pushing from the back as the express ploughed into a car stuck on the rails. In the Hatfield crash, it was pulling from the front when the rear of the train slipped off the rails causing the accident that killed four people.

Both drivers were killed, along with six passengers and two other railway staff and 82 other people were seriously injured.

Mary Dunn, whose train driver husband Steve died in the crash, said she woke to the sound of sirens and later had to sit her two young children down and say, "You know, there was a train crash this morning that involved Dad's train.

"I've got to tell you that your Daddy's dead, and you won't see him again."

Ten years after the crash, Hart said, "I believe in fate and I was meant to be there that morning."

"No deaths occurred at the point of impact with my Land Rover.

"They all occurred 700 yards down the track which I feel other people should have been held accountable for, so in my own head I've dealt with it in that fashion."
