The Titfield Thunderbolt is a 1953 British comedy film directed by Charles Crichton.
The screenplay concerns a group of villagers trying to keep their branch line operating after British Railways decided to close it. The film was written by T. E. B. Clarke and was inspired by the restoration of the narrow gauge Talyllyn Railway in Wales, the world's first heritage railway run by volunteers. The name "Titfield" is an amalgamation of the villages of Limpsfield and Titsey in Surrey, near Clarke's home at Oxted.
Ealing comedy about a group of villagers who battle to preserve the local railway line by running it themselves, until they are sabotaged in a midnight raid by a rival bus company.
