The Titfield Thunderbolt

A transportation war erupts in a small English village when the government decides to shut down the decrepit railway line. On one side is the bus company, pleased with the prospect of having a monopoly over the town's transportation system. Their opponents are the railway enthusiasts among the villagers, who persuade the richest man in town (Stanley Holloway) to help them operate the line themselves. But runaway trains make this difficult, as does sabotage from the bus company.
