R.G. LeTourneau built 6 Overland Trains and two Buggies. The Buggies were used as tire research and exploration vehicles. The Overland Trains were capable of moving goods and materials without significant roads or rail lines in extreme conditions. A few of the general terms used to describe these machines are Land Trains, Overland Trains, Tournatrains, Sno-Trains, track-less land-trains.
