28 February 1975 London Underground Moorgate Station crash

The Moorgate tube crash occurred on Friday 28 February 1975 at 08:46 on the Northern City Line, then known as the Northern Line. A southbound train failed to stop at the Moorgate terminus and crashed into the wall at end of the tunnel. Forty-three people died as a result of the crash and a further seventy-four were injured. No fault was found with the train equipment.  The driver, Leslie Newson, 55, was killed. To this day, it is still not known for certain why the driver failed to slow the train.

A system that came to be known informally as Moorgate protection, which stops a train automatically if the driver fails to brake, was subsequently introduced at dead-ends on the London Underground.
