Higher Mass Limits (HML) Schemes are now in all jurisdictions in Australia, allowing trucks to carry additional weight beyond general mass limits. Some roads in some states regularly allowing up to 4 trailers at 53.5 metres (175 ft 6 in) long and 136 tonnes (134 long tons; 150 short tons). On private property like mines, highway restrictions on trailer length, weight and count may not apply. Some of

The twin-trailer assembly is hooked up to a tractor unit via the tractor unit's fifth wheel in the customary manner. An advantage of the B-train configuration is its inherent stability when compared to most other twin trailer combinations,
972-720: Is required. Around container ports in Australia exists what is known as a super B-double; a B-double with an extra axle (total of 4) on the lead trailer and either three or four axle set on the rear trailer. This allows the super B-Double to carry combinations of two 40 foot containers, four 20 foot containers, or a combination of one 40 foot container and two twenty foot containers. However, because of their length and low accessibility into narrow streets, these vehicles are restricted in where they can go and are generally used for terminal-to-terminal work, i.e. wharf to container holding park or wharf-to-wharf. The rear axle on each trailer can also pivot slightly while turning to prevent scrubbing out
1026-750: The British Armed Forces in the Second Boer War . Lord Kitchener stated that he had around 45 steam road trains at his disposal. A road train devised by Captain Charles Renard of the French Engineering Corps was displayed at the 1903 Paris Salon.

2268-479: The primary purpose of the railway was the transport of live beef cattle to markets in the east of the state. Dajarra railway station was reputed to be one of the busiest cattle transfer sites in the world. Prior to construction of the railway, it is likely that early roads were cut from both Cloncurry and Dajarra to provide access for wheeled vehicles to the pastoral runs and mining settlements. Over time these tracks may have been improved and extended to eventually form

However, the divisional board appeared to be completely inactive, perhaps because
2592-885: The turntable mounted on the forward trailer results in the B-train not requiring a converter dolly as with all other road train configurations. It is this feature above all else that has ensured its continued development and global acceptance. Reversing is simpler as all articulation points are on fifth wheel couplings. B-train trailers are used to transport many types of load and examples include tanks for liquid and dry-bulk, flat-beds and curtain-siders for deck-loads, bulkers for aggregates and wood residuals, refrigerated trailers for chilled and frozen goods, vans for dry goods, logging trailers for forestry work and cattle liners for livestock. In Australia, standard semi-trailers are permitted on almost any road. B-doubles are more heavily regulated, but routes are made available by state governments for almost anywhere that significant road freight movement

Provided with financing of about 2000 pounds and inspired by the tracking abilities of the Government roadtrain, Johannsen began construction. Two years later his first road train was running. Johannsen's first road train consisted of a United States Army World War II surplus Diamond-T tank carrier , nicknamed "Bertha", and two home-built self-tracking trailers. Both wheel sets on each trailer could steer, and therefore could negotiate
2754-480: Was discovered in Duchess in 1897 on a pastoral run, which led to the opening of a mine and the founding of the town. The railway arrived in 1912. The town of Duchess is surrounded by cattle stations, including Stradbroke and Bushy Park. The railway branch line arrived in the small settlement of Dajarra in 1917, and the town grew around it. There were already many pastoral runs in the surrounding area and further west, and
