In the early 1950s, the LeTourneau company revolutionized transportation by developing a series of overland trains that could conquer almost any terrain. These oversized semi-trailer trucks were designed to handle logistics needs without relying on local roads or rail systems, allowing them to operate in even the most remote back-country areas. The US Army took notice and commissioned three experimental units, with the largest reaching an incredible 600 feet (183 meters) long - a record that still stands today for the longest off-road vehicle ever built. Road trains are still used in various roles today, but the US Army's experimental models and their derivatives appear to be the only ones designed specifically for off-road use. The LCC-1 was so successful that it led to the development of an even larger version, the TC-497 Overland Train Mark II, in 1958. The Mark II boasted a massive six-wheeled cab over 30 feet (9.1 meters) tall and no longer articulated due to its advanced steering system. Its smaller turbine engine allowed for a spacious interior that could accommodate a crew of six with sleeping quarters, toilets, and a galley. The train was even equipped with radar, making it a cutting-edge vehicle at the time. For testing purposes, two additional power cars and ten cargo cars were built, bringing the total length to over 570 feet (170 meters). On flat ground, the Mark II could carry an impressive 150 tons of cargo at speeds of around 20 mph. Its range was typically between 350 to 400 miles (560 to 640 kilometers), but additional fuel trailers could be added to extend its capabilities. Final specifications were completed in 1960, and construction took most of 1961. After preliminary testing, the Mark II was handed over to the Army in February 1962 and shipped to the Yuma Proving Ground in Arizona for further evaluation under Project OTTER (Overland Train Terrain Evaluation Research). The vehicle performed well, but ultimately fell out of favor with the Army as newer heavy-lift helicopters like the S-64 Skycrane made the train concept seem outdated. The Mark II remained unused for a time before being put up for sale in 1969 for $1.4 million. Today, only the control cab remains at Yuma, while the rest was sold to a local scrap dealer. Despite this, the Mark II retains its record as the longest off-road vehicle in the world.
