The Titfield Thunderbolt is a 1953 British comedy film directed by Charles Crichton and starring Stanley Holloway, Naunton Wayne, George Relph and John Gregson. 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. "Titfield" is an amalgamation of the names Titsey and Limpsfield, two villages in Surrey near Clarke's home at Oxted.
