A land train is a type of trucking vehicle used to move road freight more efficiently than semi-trailer trucks. It consists of two or more trailers or semi-trailers hauled by a prime mover. The term "road train" is used in Australia, where they have the longest and heaviest road-legal road trains in the world, weighing up to 200 tonnes. Australian road trains have horizontal signs front and back with 180 mm high black uppercase letters on a reflective yellow background reading "ROAD TRAIN".
In addition to this, there is another type of land train called a trackless train, which is made to resemble a real locomotive and is used for transporting passengers short distances, typically in tourist resorts.
There are also some unique land trains that were developed for specific purposes. For example, the US Army developed land trains for use in logging operations. These were trackless land trains with a 500 horsepower Cummins diesel engine connected to a 16-speed manual transmission. Another example is LeTourneaus Land Trains, which are the worlds largest overland vehicles. These were developed in the 1950s and were used to transport heavy equipment and supplies to remote locations.
Overall, a land train is a type of trucking vehicle used for efficient transportation of freight or passengers over long distances.
