Snowdrift at Bleath Gill is a 1955 British Transport Film documentary directed by Kenneth Fairbairn. The 10-minute-long film presents a first-hand account of a team of British Railways workmen freeing a goods train stuck in a snowdrift on the South Durham and Lancashire Union Railway at Bleath Gill in the Pennines on the border between County Durham, Yorkshire and Westmoreland. A fine example of an industrial documentary, the British Film Institute call it "One of the most outstanding films of its kind".
