Life-Line of the Nation is a short film from the Association of American Railroads and produced by Carl Dudley in the mid-1940s (most likely 1944) that shows how America’s railroads are ensuring the defense of the nation by meeting the transportation needs of a country mobilized for war. The film opens with a shot of a train moving through snowy terrain. Off in the distance, a train goes over a bridge (01:22). There are several shots of various trains moving along tracks.
