The Ghan, Australia

The Ghan offers the world's longest north–south train journey on a single continent, spanning 2,979 kilometers from Adelaide to Darwin. This epic three-day trip cuts through Australia's red center, where the desert emptiness outside your window becomes meditative rather than monotonous. Over 84% of passengers rate the experience as 'life-changing' in onboard surveys, and the train's dome cars provide 360-degree views that outperform #6 Jacobite Steam Train's open-window panoramas by offering climate-controlled comfort across 40°C temperature swings.
