Harrow and Wealdstone rail crash

The Harrow and Wealdstone rail crash was a three-train collision at Harrow and Wealdstone station in Wealdstone, Middlesex during the morning rush hour of 8 October 1952. 112 were killed and 340 injured, 88 of these being detained in hospital, and it remains the worst peacetime rail crash in the United Kingdom.
An overnight express train from Perth crashed at speed into the rear of a local passenger train standing at a platform at the station. The wreckage blocked adjacent lines and was struck within seconds by a "double-headed" express train travelling north at 60 mph . The Ministry of Transport report on the crash found that the driver of the Perth train had passed a caution signal and two danger signals before colliding with the local train. The reason for this was never established, as both the driver and the fireman of the Perth train were killed in the accident.
