Why Are Road-Trains Only Found in Australia?

Why are road trains only found in Australia? These multi-trailer mega trucks are the longest legal vehicles on Earth and they only exist because of a collapsed camel economy, a broken railway system, and one bush mechanic with a welding torch. In this video, we break down the real history behind the Australian road train: how camel caravans run by Afghan cameleers in the 1800s built the original blueprint, why America tested multi-trailer trucks decades earlier and abandoned the idea, and how a self-taught mechanic named Kurt Johannsen solved the trailer-swing problem that no engineer could fix. We also dig into why Australia's mismatched railway gauges left the country with no choice but trucks, why the government rebuilt entire highways just to fit these convoys, and how road trains today move the beef, iron ore, and lithium that end up in your phone, your car, and your EV battery. If you've ever wondered why Australia has road trains and the rest of the world mostly doesn't, this is the full story — outback history, transport engineering, and supply chain logistics in one video.
