The Qinghai-Tibet Railway is the world’s longest and highest elevation railway. The highest point of the railway is 5,072 meters, built on Tanggula Mountain. There are about 960 km of the railway built over 4000 meters height above sea-level and 550 km built in permafrost areas. Many foreign media evaluate that it is the most difficult railway project in the history and can be matched with the Great Wall.
With the success of this 1,142 km long railway from Golmud to Lhasa, the development history of China has opened a new chapter. The Chinese people have created wonders in “the roof the world”.
