Did the Sno-Train Have Tire Chains for the Ice?

Well, kind of. The Sno-Train’s wheels came equipped with what LeTourneau called traction lugs. Breaking it down a little more simply, the traction lugs were long rubber pieces or cables that were on the tread bearing part of the tire. The rubber or cable was attached to the wheel, or rim, by other chain and cables. The connection points and traction lugs varied in design over the years. The drawing below shows traction lugs for the last Overland Train called the Overland Mark 2. The traction lugs on the later Mark 2 train had pointy, claw-like attachments for the lugs. While, the traction lugs attachments for the Sno-Train rims used circular, washer-like attachments for the traction lugs.

The Sno-Train also used a more cable-like lug to wrap around the massive Firestone 120x48x68 tires. The traction lugs were not used all that often during real world missions. The Sno-Train tracked extremely well in snow and ice. Which, is not to say that it did not have its fair share of jackknifes. More on that in my book.

The Sno-Train’s mechanical and electrical connections are being inspected in Houghton, Michigan – dated 3-10-56
