On the Alaska Freight Lines Sno-Freighter’s third journey resupplying the Distant Early Warning (DEW) Line stations, it jackknifed and caught fire. The machine sat immobilized for five years in a valley east of Eagle, AK, just inside the Yukon Territories. The United States Army and the Sno-Freighter’s owner set out to recover the Sno-Freighter; they connected the Sno-Train’s electrical system and a portable generator (to unlock the wheel motors) to the Sno-Freighter. Both machine’s wheel motors were powered by the Sno-Train’s 600-hp Cummins VT-12 engine.
The Sno-Train struggled to get moving at first. But, a CAT provided an initial tug up a hill, when moving forward from a dead stop, or when the load was simply too much to overcome. You can read more about this story in my book – https://www.amazon.com/dp/B0BFL91FX6.
