The Harrow and Wealdstone rail crash was (and as of March 2015 remains) the worst peacetime rail crash in the United Kingdom: a multiple train collision at Harrow and Wealdstone station, in London, on the morning of 8 October 1952. An express train from Perth crashed at speed into the rear of a local passenger train stopped at the station's platform no 4. The wreckage blocked adjacent lines, and within a few seconds a "double-headed" express train, travelling north at 60 miles per hour (100 kph), crashed into the Perth train's locomotive. There were 112 fatalities and 88 people were detained in hospital.
