 Three road trains, Western Australia A road train is a trucking concept used in remote areas of Australia, the United States, and Western Canada to move bulky loads efficiently. The term "road train" is most-often used in Australia. In the U.S. and Canada the terms "triples", "Turnpike doubles" and "Rocky Mountain doubles" are commonly used for longer combination vehicles (LCVs).[1] Download high resolution version (1024x683, 96 KB) Wikipedia does not have an article with this exact name. ...

Overview

Australia has the largest and heaviest road-legal vehicles in the world, with some configurations topping out at close to 200 metric tons. The majority though are between 80 and 120 tonnes. Two-trailer road trains, or "doubles" are allowed in all Australian states except Victoria and Tasmania, and into two capital cities - Adelaide in South Australia, and Perth in Western Australia. Three trailer road trains (triples) operate in western New South Wales, western Queensland, South Australia, Western Australia and the Northern Territory, with the last three states also allowing AB-Quads (3.5 trailers). Darwin, NT, is the only capital city in the world that will allow triples and quads to within 1km of the CBD. A tonne (also called metric ton) is a non-SI unit of mass, accepted for use with SI, defined as: 1 tonne = 103 kg (= 106 g). ...
Road trains can be unwieldy, and driving and maneuvering them safely without unduly obstructing traffic is only possible because of Australia's very light traffic conditions, and extremely flat and straight terrain through the outback. Furthermore, there are tough regulations regarding licensing and driving experience. The multiple dog-trailers are unhooked, the dollys removed and then connected individually to multiple trucks at "assembly" yards when the road train gets close to populated areas.

Road trains are used for transporting all manner of materials, with livestock, fuel, mineral ores and general freight the most common. Their cost-effective transport has played a significant part in the economic development of remote areas, with some communities totally reliant on a regular service. Sheep are commonly bred as livestock. ...

Overtaking a road train can be quite difficult (and, on Australia's many dirt roads, often impossible). Patience, assistance from the driver, and large amounts of clear road are required. Although it is illegal, many road train drivers help by blinking their right-turn indicators a couple of times to indicate that the road ahead is clear. Road train and truck drivers can see much further than cars.
 A road train being unloaded at Timber Creek. When the road train trailers are empty, and there is no available freight, it is common practice to stack them. This is commonly referred to as "doubled-up" or "doubling-up". Sometimes, if many trailers are required to be moved at the one time, they will be tripled stacked, or "tripled-up". This method only works with flat-top trailers. Image File history File linksMetadata Download high-resolution version (2272x1704, 694 KB) This image was copied from wikipedia:en. ...

In the United States, trucks on public roads are limited to three trailers (in some states only two), and the term "road train" is not commonly used. Triples are used for long-distance less-than-truckload freight hauling (in which case the trailers are shorter than a typical single-unit trailer) or resource (such as ore or aggregate) hauling in the interior west. Triples are typically marked with "LONG LOAD" banners both front and rear. Less-Than-Truckload (LTL) shipping is the transportation of relatively small freight. ...

B-double A B-double (B-train) consists of a prime mover towing a specialised trailer that has a fifth-wheel mounted on the rear towing another semi-trailer, resulting in two articulation points. semi-trailer truck with sleeper behind the cab. ...
C-train A C-train is a semi-trailer attached to a fifth-wheel on a C-dolly. The C-dolly is connected to the tractor or another trailer in front of it with two draw-bars, thus eliminating the drawbar connection as an articulation point. One of the axles on a C-dolly is self-steerable to prevent tire scrubbing. semi-trailer truck with sleeper behind the cab. ...

Rules and Regulations
Signage A road train has signs front and back in large black letters on a yellow background reading "ROAD TRAIN".
Combination Lengths - B-Double- 26m max.
- B-Triple- 33.5m max.
- Double road train- 36.5m max.
- Triple and AB-Quad road trains- 53.5m max.
Operating Weights Operational weights are based on axle group masses, as follows: - Single axle- 6.0t (metric)
- Tandem axle grouping- 16.5t
- Tri axle grouping- 20.0t
Therefore, a B-Double would weigh 62.5t (6 + 16.5 + 20 + 20). A double road train would have an operational weight (without concessions) of 79t (6 + 16.5 + 20 + 16.5 + 20). A triple is 79t + 36.5 (16.5 + 20), giving an all up weight of 115.5t. Quads weigh in at 135.5t(extra 20t). Concessional weight additions (1 - 2.5t per group) can see a quad end up weighing 149t. If a tri-drive prime mover is utilised, along with tri-axle dollys, weights can reach nearly 170t.
Speed Limits The Australian national heavy vehicle speed limit is 100 km/h, excepting: - NSW, Queensland and South Australia, where the speed limit for ANY road train is 90 km/h;
- Western Australia and the Northern Territory, where the speed limit for road trains is 100 km/h.
