A freight train travelling between Kirkby Stephen and Barnard Castle becomes snowbound in the Westmorland hills. The Motive Power, Operating and Engineering Departments go to work with the snowploughs to reach the trapped train. The team dig clear and thaw out moving parts, and finally two rescue engines help to clear the line.
