World's Most Extreme Railway Megastructure
Show Details
Featured: This is the story of the battle to build a railway across one of the most extreme environments on Earth. To lay down over a thousand kilometers of track in a remote wilderness. Driving 7 tunnels and raising 675 bridges - all at an altitude where even a simple breath is nearly impossible to come by. Nearly 140,000 workers and 2000 medics struggled for 5 years to conquer this hostile environment to complete. The Qinghai-Tibet railway, the highest, most extreme railway in the world!
