Are Australian road trains the solution to the US driver shortage?

Originally published in Supply Chain Dive

North Dakota approved legislation to pilot the freight method as a way to deal with increased demand for drivers amid high turnover rates. Mike Notarangeli discusses the challenges of "road trains" saying, "There are advantages of road trains — increased capacity, improved efficiency, better driver utilization — but there are downsides as well, including increased maintenance on equipment, increased safety risk and limited access.”


In solving for crucial supply chain issues, Australia found a workaround that could have implications for driver shortages and transportation hurdles in the U.S.

Australia's supply chain must navigate its landmass of 2.96 million square miles, people and businesses dispersed through the Outback and an infrastructure better suited to nimble vehicles. While most of the population lives in coastal cities, many live in villages widely separated by deserts and connected by highways and dirt roads. Residents in these areas work on cattle and sheep farms or in mining, which requires the movement of large equipment.

The Aussies found a unique solution to transport items such as excavators, hydraulic shovels and dozers: road trains.

A road train is an engine with a string of trailers attached, a mega-tandem, said Michael Notarangeli, executive vice president of logistics at Maine Pointe, a global supply chain and operations consultancy. The trailers are known as dog or pup trailers because they were historically used at dog farms. Australia has the longest and heaviest road-legal road trains in the world, weighing up to 200 tons, according to Vintage Road Haulage in Perth.

The ability to transport multiple trailers with one engine holds promise for optimizing supply chain operations and increasing efficiency in rural areas — so much so that a North Dakota state senator introduced a bill to pilot road trains in the state. The method isn't perfect for every scenario and comes with limitations and drawbacks.

Optimization is top of mind

"Ideally, road trains would operate in rural areas where there is less congestion," Notarangeli told Supply Chain Dive via email. "If you can envision a mega-tandem they are best operated on straight roadways — 90-degree turns are impossible."

Optimization, efficiency and revenue are top-of-mind for supply chain and logistics professionals. Road trains might be one way to achieve those goals, Torsten Welte, global VP and head of the Industrial Business Unit for Aerospace and Defense, plus Travel and Transportation at SAP, told Supply Chain Dive.

"It's always the optimization of how do you get more transported by less effort," he said. "Establishing these super-long, multi-trailer mega trucks, where you don't have the infrastructure for rail, [but still] need to get the same kind of flexibility and capacity in place [makes sense]."

With trucks, Welte added, there is the engine and the driver, but as in rail, the more trailers you have on it, the more efficient you are. "You can carry more freight and that means more revenue."

Addressing the driver shortage

According to a July report from the American Trucking Associations (ATA), 60,800 more drivers were needed at the end of 2018 to meet the country's demands for freight services.

"The combination of a surging freight economy and carriers' need for qualified drivers could severely disrupt the supply chain. The increase in the driver shortage should be a warning to carriers, shippers and policymakers because if conditions don't change substantively, our industry could be short just over 100,000 drivers in five years and 160,000 drivers in 2028," ATA Chief Economist Bob Costello said in the report.
