Nejen na Sibiři si řidiči nákladních vozů musí poradit s vodními živly. Přebrodit více či méně rozvodněné řeky umí i australští řidiči silničních vlaků.
represents the largest road trains operating in Australia, and therefore, the world. Called a "Powertrain" or a "Body and six", these machines operate at The Granites Gold Mine in the western Northern Territory, and are used in place of 200t dump trucks, because of the distances involved on the haul run. A 600 hp (450 kW) 19 L (1,200 cu in) Cummins engine powers the prime mover, whilst a 400 hp (300 kW) Cummins engine is installed in the rear trailer of the B-double, driving through an automatic transmission, giving a total of 1,000 hp (750 kW). Weights of 460 t (453 long tons; 507 short tons) are achieved with ore loading in side-tipper bodies on a 100 km (62 mi) round trip. As these trucks operate on private property, they are not subject to governed weight and length rulings, but instead are utilised in the most efficient way possible.
