The Titfield Thunderbolt (1953) on Netflix

Volunteers take over their local passenger train service (against bus company resistance) when the government announces its closure.

The residents of a small English village are about to lose their ancient railway. They decide to attempt to rescue it from closure by buying up the line and running it themselves, putting them in direct competition with the local bus company.

When British Railways announce the closure of the Titfield to Mallingford branch line a group of local residents make a bid to run it themselves, backed by a monied member of the community who is attracted by the complete lack of licensing hours on trains. Unfortunately the local bus company starts to use methods that can hardly be seen as fair competition, to the extent that the whole project is threatened.
