The TC-497 Overland Mark 2 (TC-497) 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. After fabrication and production at LeTourneau’s Longview, TX factory, the TC-497 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 TC-497. It is now on display and available to view.
YouTuber Calum recently (2023) visited the TC-497 in Yuma, AZ. Check out his video below.
