A road-train is a long combination vehicle consisting of a prime mover pulling multiple trailers. In Australia, road-trains can be over 53 meters long and weigh more than 200,000 kg. Why are road-trains mainly used in Australia and not other countries? Australia's vast land area, low population density in remote regions, limited rail network coverage, and suitable road infrastructure make road-trains an efficient and cost-effective transport solution unique to the country. What challenges does Australia face in transitioning road-trains to electric vehicles? The heavy weights and extreme lengths of road-trains, combined with the vast distances and sparse charging infrastructure in Australia, make electric road-trains currently impractical and likely decades away from feasibility. ## Full Transcript — Download SRT & Markdown 00:00 Speaker A Australia is known for its unique and extensive use of road-trains. 00:05 Speaker A Which are exceptionally long and heavy vehicles. 00:08 Speaker A But why is it only in Australia you see road-trains? 00:13 Speaker A In this video, we will dive into the multiple reasons that Australia uses road-trains. 00:18 Speaker A But first, you might even be wondering, what is a road-train? 00:23 Speaker A A road-train is a type of long combination vehicle that consists of a prime mover, the pulling unit, which is pulling multiple trailers or semi-trailers connected in a series. 00:35 Speaker A Road-trains are characterized by their exceptional length and weight compared to standard truck and trailer configurations. 00:44 Speaker A In Australia, road-trains can consist of two to four trailers, however, sectors such as mining, agriculture, bulk freight, use even longer combinations of up to seven trailers. 00:56 Speaker A The first Road-train was invented in the 1930s. 00:59 Speaker A The road-train consists of an eight-wheeled tractor unit. 01:03 Speaker A Pulling two trailers. 01:07 Speaker A The road-train was around 22 meters long. 01:12 Speaker A And weighed around 36,000 kg. 01:17 Speaker A Today, the total length of a road-train can reach up to over 53 meters. 01:23 Speaker A 174 feet, and they can have a total gross weight of over 200,000 kg. 01:29 Speaker A This massive weight and long road-trains. 01:33 Speaker A Have some infrastructure limitations. 01:37 Speaker A As there may be certain roads, bridges, or areas with weight or length restrictions that road-trains must comply with. 01:45 Speaker A There can therefore be a major planning task in choosing the right route through the large country. 01:53 Speaker A This leads us to the first reason that Australia uses road-trains. 01:59 Speaker A Australia is the world's sixth largest country by land area. 02:04 Speaker A With vast expanses of remote and sparsely populated regions. 02:10 Speaker A Road-trains provide an efficient and cost-effective means of transporting goods across long distances in these areas. 02:18 Speaker A Where there may be limited infrastructure and transportation options. 02:23 Speaker A The use of road-trains allows for the transportation of larger quantities of goods in a single trip. 02:30 Speaker A Reducing the number of trips required. 02:33 Speaker A And overall transportation costs. 02:37 Speaker A Imagine an additional cost in operating four trucks with four drivers, who all must have wages, and the added wear and tear on the truck engine. 02:48 Speaker A Rather than one truck pulling four to five trailers, moving the same cargo. 02:54 Speaker A This is particularly advantageous in Australia's remote regions, where distances between towns and cities can be significant. 03:03 Speaker A Here, routes can extend over thousands of kilometers. 03:08 Speaker A And the driver can be on the road for weeks. 03:12 Speaker A In order to allow such long and heavy trucks, Australia has developed a regulatory framework to accommodate the safe operation of road-trains. 03:23 Speaker A It includes specific licensing requirements, vehicle design standards, and road infrastructure guidelines to ensure the safe and efficient operation of these long combination vehicles. 03:33 Speaker A This may include oversize load signs. 03:37 Speaker A Reflective tape. 03:39 Speaker A And warning flags. 03:41 Speaker A The specific requirements for signage and markings can vary between states and territories. 03:50 Speaker A But now, you may be sitting and thinking, why don't they just load the goods on a train and transport it? 03:57 Speaker A Which leads us to the next reasons. 04:01 Speaker A Australia's train network, compared to densely populated countries with extensive rail networks, such as China, Japan, or European nations. 04:10 Speaker A Australia's train network is limited in terms of coverage. 04:14 Speaker A The train network primarily serves the major cities and some regional centers along the densely populated Eastern and Southeastern coasts. 04:25 Speaker A In the interior and remote regions, they may have limited or no access to the train network. 04:33 Speaker A This is also because of a low population density in the remote areas, making it challenging to justify the economic viability of extensive rail infrastructure. 04:43 Speaker A The sheer size of Australia's landmass and the challenging terrain in many remote regions present significant cost and feasibility challenges for expanding the train network. 04:55 Speaker A Why the solution of the Road-trains came alive, which at the same time seemed to be a faster and more economical solution to the Australians. 05:03 Speaker A However, the Australian road network is generally well suited for road-trains, with long, straight stretches of highways and roads that facilitate their maneuverability. 05:14 Speaker A These roads are designed to handle the size and weight of road-trains, including the necessary turning radii and bridge and overpass clearances. 05:22 Speaker A Making it suitable for road-trains. 05:26 Speaker A So, the main reasons why Australia is the only place with road-trains is Australia's unique geography. 05:34 Speaker A Limited train network coverage, low population density in remote areas. 05:40 Speaker A Suitability of the road network have contributed to the prominence of road-trains as a transportation solution. 05:48 Speaker A This has made up for some unique trucking rules, as you won't find other places that allow such long trailer combinations. 05:55 Speaker A And such high total weights. 05:58 Speaker A Also, Australia is one of the few places where you regularly will see both the conventional truck with a long hood and the shorter cab-overs. 06:07 Speaker A Cab-over trucks are often favored in urban areas or applications that require maneuverability and easy access to loading docks. 06:16 Speaker A Conventional long-nosed trucks on the other hand, may be preferred for long-haul or heavy-duty operations, where aerodynamics and driver comfort play a significant role. 06:27 Speaker A But what does the future of road-trains look like? 06:33 Speaker A When you look at the constant demands for reducing emissions and increased requests for greener solutions. 06:41 Speaker A First of all, the current emission standard in Australia is Euro 5, where most of Europe is 6. 06:49 Speaker A And the extended version, Euro 6C, with even stricter emission requirements. 06:56 Speaker A Also, both in Europe and America, more and more electric truck versions are coming. 07:03 Speaker A But just try to imagine an electric truck pulling over 200,000 kg. 07:09 Speaker A And 4, 5 or 6 trailers. 07:12 Speaker A Not to mention the logistics of establishing a charging network in such a large country, with such long distances from region to region. 07:23 Speaker A We think it will be decades, or if it ever will be a feasible solution. 07:29 Speaker A We can just wait and see. 07:32 Speaker A What do you think? 07:34 Speaker A Will all trucks be replaced by electric solutions in the future? 07:39 Speaker A Leave a comment below and let us know your opinion. 07:42 Speaker A This was everything for today. 07:45 Speaker A We hope you enjoyed. 07:47 Speaker A Thanks for watching and remember to subscribe for much more.
