Model Powered Overland Train Mk II

R.G. LeTourneau, Inc. began work on the Overland Mk II as early as 1958. Unlike the previous Overland Trains, the Mk II was years in the making. Engineers and laborers spent large swaths of time with the larger train concept, designing suspension, wheel motor cooling, and other components and features. The model Overland Mark II you see below, in R.G. LeTourneau’s Annual Report, is one stage of development used to understand steering and trailer tracking. The Mk II was handed over to the United States Army in Mar/Apr of 1962, where it was transported to the Yuma Proving Grounds for testing.
