In the 1950s, [[LeTourneau Technologies|LeTourneau Inc.]] developed several '''overland trains''', essentially oversized [[semi-trailer truck]]s that could travel over almost any terrain. Their intention was to be able to handle [[logistics]] needs without being dependent on local road or rail systems, allowing them to operate in back-country areas. The [[US Army]] had three experimental units built, the largest reaching almost {{convert|600|ft|0}} long, which holds the record for the longest off-road vehicle. [[Road train]]s are in use in certain roles today, but the US Army examples and a few derivatives appear to be the only off-road examples built.
