Poster produced by British Railways (BR) to promote the efficiency of Whitemoor Marshalling Yard, 'a focal point between East England and the North'. The poster shows a diagram of the lay-out of the yard, with captions detailing what happens at the reception sidings, the Hump and the marshalling yard proper. BR was keen to call attention to the efficiency of 'the busiest railway system in the world'. Artwork by F Donald Blake.
