The Highest Railway on Earth: How Trains Survive Tibet

The Qinghai-Tibet Railway climbs higher than any other railway in regular operation, crossing permafrost, extreme cold and air thin enough to make altitude sickness a real concern. This documentary looks at how engineers keep the track stable, how passenger trains supply oxygen, why bridges and heat pipes matter, and what it takes to run a railway across the Tibetan Plateau.
