Below, the Overland Train MkII rolls along with a Cargo Car and Power Car in Yuma, AZ. There is no backstory for this image and the source is unknown. This week was largely spent working on the TC-497 chapter. Phase I of the Army’s contract for R.G. LeTourneau, Inc. to create the Overland Train, was to build out the preliminary design. Using data from the Sno-Train (LCC-1), LeTourneau engineers worked out the gaps and started work on the machine you see below.
