The Eltham Well Hall rail crash was an accident on the British railway system that occurred on 11 June 1972 at approximately 21:35. An excursion train from Margate to Kentish Town derailed on a sharp curve at Eltham Well Hall station, Eltham, London. The curve had a maximum permitted speed to be taken at 20 miles per hour (32 km/h) but the train was estimated to have been travelling at 65 miles per hour (105 km/h) resulting in the locomotive and all but one of the ten carriages derailing.
