R.G. LeTourneau’s TC-497, or the Overland Train MkII, never saw production outside of one unit. It was the most engineered out of all of the Overland Trains. The model MkII seen below was one of the first steps in testing the S-curve ability of the design. This model was electrified and tested. You can see the toy Jeep for scale.
