Wolves of the Rail is a 1918 American silent Western film produced, directed by, and starring William S. Hart.

[1] As described in a film magazine,[2] "Buck" Andrade (Hart), an outlaw, promises his dying mother (Midgley) that he will reform himself.

Taking a letter of introduction from a wounded man, he becomes a detective for the railroad, which he had previously held up several times.

He is successful in capturing several bandits and also wins the love of Faith Lawson (Vale), who is a towerman (a type of railroad signalman).

When the real detective recovers from his wounds and returns to duty, he discloses the true identity of Buck.
