LeTourneau's INSANE Overland Trains

Visit overlandtrains.com for amazing pictures and information about LeTourneau's Overland Trains.The TC-497 Overland Train Mark II was the longest off-road vehicle ever built – a 570-foot, 54-wheel-drive monster designed to haul 150 tons across Arctic terrain where no roads existed. Powered by four gas turbine engines producing nearly 5,000 horsepower, this incredible machine was built by R.G. LeTourneau, the man who supplied 70% of Allied earthmoving equipment during World War II.In this documentary, we explore the Cold War origins of the land train program, the desperate need to build radar stations across the Arctic, and the engineering genius of a sixth-grade dropout who held nearly 300 patents. From the first Tournatrains hauling lumber through forests to the massive TC-497 abandoned in the Arizona desert, this is the forgotten story of machines that pushed the limits of what was possible.
