Australian Road-Trains are trucks with massive amounts of torque that tow a whole bunch of trailers across the Outback. Since there are no railroads this is the most convenient way to haul a lot of stuff from A to B. Also, if a truck breaks down in the Outback there\’s nowhere to get it fixed, so you\’ll have trucks towing other trucks along with their trailers. Check out some of the images here and here. Very cool stuff in a Mad Max sort of way.
