The Sno-Train arrived in Houghton Michigan in the middle of February 1956. It would stay there until early April 1956, where it was tested in a variety of snow and ice conditions. R. G. LeTourneau took the opportunity to visit Michigan in early March to see how his new machine was progressing. During the tests, the Sno-Train tried out the traction lugs for the first time. These were the equivalent of tire chains. There appear to be 6 traction lugs present on each wheel.
