A Steam Train Passes is a 1974 Australian short film set in the 1940s, featuring the construction and operation of C38 class locomotive 3801.

The main part of the film shows the train travelling through the New South Wales countryside through disparate locations including the Sydney suburbs, Hawkesbury River Railway Bridge, Ten Tunnels Deviation, Polona signal box Blayney station and the Picton-Mittagong loop line.

These scenes are interspersed with vignettes of life the 1940s including a travelling salesman, a country wedding in a church at Georges Plains, and two soldiers heading off to war, having their last drink in a pub, the Hotel Alexander in Rydal.

The only "acting" credits are for the driver Chris O'Sullivan and fireman Harold Fowler, both employees of the Public Transport Commission.

Footage has been used in Sarah, The Winds of Jarrah, Sirens, Rabbit-Proof Fence, True Believers, Curtin and several documentaries.
