For all the people asking, "Why don't you use a railroad?" These trucks mostly use existing roads. A train cannot stop to visit individual properties that may be hundreds of kilometers apart. Railroads are used to connect major hubs. Australians, like most people, are for a given environment. uses the system that works best. I live in rural Australia and share the roads with these trucks. Most road train drivers signal to let you know when it is safe to cross them, but believe it or not, they are often the ones who overtake retired passengers in their motor homes and caravans.

The modular part is much more interesting than some kind of long truck. In my rail experience we usually use 8,500 ft long trains weighing up to 13,000 tons, but they get stuck on a single track. These modular vehicles must be extremely expensive to operate.

I'm British and this reminds me of when I lived and worked in north Sydney. I would find myself on the road around 7:30 p.m. every weekday, and at exactly the same time, I would see two road trains (small compared to those shown here) in the distance in my rearview mirror. Let me tell you something. If you're not used to it, one of these goddamn speed bumps, catching up with you, and complete with roo bars isn't for the faint-hearted esp if you're using a can of Korean sardines. The message was loud and clear;  get out of the way. NOW.
