An archive video recently released buy the U.S. Army Transportation Museum shows several logistics train concepts, including the Sno-Train. The video, created by The United States Army Transportation Research Command, shows several early train concepts, including a small dozer with covered wagons with wooden wheels.

Later concept drawings closely mirrored LeTourneau’s Tournamotive Trackless Train concept, which was his first.

The video shows four concept drawings similar in design to LeTourneau’s. The first two drawings depict wheeled trailers with a tracked control car. The later two drawings in the video show a wheeled control car.

The video concludes with a little over a minute of the Sno-Train maneuvering over snowy terrain near a body of water. The following images were captured from the video, which was likely filmed in Houghton, MI, USA. The Sno-Train was in Houghton for testing at the Keweenaw Field Station of Snow Ice and Permafrost Research Establishment (SIPRE) from March 1956 to the end of May 1956.
