Planned at first for the development of products on the cold ground, they were later utilized as a part of Alaska as a method for transport for military use by the United States. One of these, the TC-497 Overland Train MkII, with its more than 204 meters long still holds the world record for the longest street vehicle ever built.The first overland train was the model VC12 “Tournatrain” worked in a solitary duplicate and tried by LeTourneau in February 1953.It comprised of an escort made out of a tractor and three trailers for stacking, each of the vehicles laid on two mechanized tomahawks for an aggregate of 16 wheels, all drive. The caravan was pulled by a powertruck, driven by Cummins diesel motor VT-12 equipped for conveying 500 hp gross, which nourished the four electric engines put one for every vehicle. Following a couple of months of testing, the maker chose to twofold the length by including four trailers; to bolster the expanded requirement for force on the powertruck was introduced a second Cummins diesel motor, conveying the aggregate gross energy to 1000HP.
