The Clapham Junction rail crash was a serious railway accident involving two collisions between three commuter trains at 08:10 on the morning of 12 December 1988.
The collisions occurred 800 m (half a mile) southwest of Clapham Junction railway station in southwest London. Thirty-five people died and five hundred were injured, making the crash one of the worst in the UK in recent times.
Pupils from the adjacent Emanuel School were first on the scene of the disaster and helped save the lives of many. They were commended for their service by the Prime Minister, Margaret Thatcher.
