LeTourneau TC-497 Overland Train MkII

LeTourneau made one final stab at building the ultimate land train. Designed to traverse arctic conditions as well as sand and desert, the six-wheeled TC-497 Overland Train MkII used four Solar gas-turbine engines (at 1,170hp each, that’s 4,680hp total) to spin generators that delivered juice to 54 total motors – one for each of its wheels. Of its 12 trailers, two were dedicated just to carrying the turbines and generators.
