The Polmont rail accident, also known as the Polmont rail disaster, occurred on 30 July 1984 to the west of Polmont, near Falkirk, in Scotland. A westbound push-pull express train travelling from Edinburgh to Glasgow struck a cow, which had gained access to the track through a damaged fence from a field near Polmont railway station. The collision caused all six carriages and the locomotive of the train to derail, killing 13 people and injuring 61 others. The accident led to a debate about the safety of push-pull trains on British Rail.
