Description: This home movie from 1962 captures R. G. LeTourneau demonstrating the TC-497 Overland Train Mark II developed by his company, R.G. LeTourneau, Inc., to military officials in Longview. Essentially a chain of oversized semi-trailer trucks, the train could maneuver over almost any terrain, allowing it to operate in areas without local road or rail systems. The Army contracted LeTourneau for the manufacturing of several experimental overland trains, including the Mark II. All were eventually abandoned. Capable of growing to any length, the Mark II remains the longest off-road vehicle in the world.
