The Overland Mark 2 was a 572 feet long Overland Train, the longest out of the six. It used 3 SOLAR 10MC gas turbines to provide electrical energy to each LeTourneau Electric Drive, with a fourth SOLAR gas turbine in the control car for scouting operations or additional electricity production. The Mark 2 never left the Army’s Yuma Proving Ground for combat duties. It was sold at auction. Fortunately, the Yuma Proving Ground Heritage Center was able to acquire the Mark 2. It is now on display and available to view.
