The scenery along the Qinghai-Tibet Railway that is known as the highest railway in the world is breathtakingly attractive. Amidst the numerous high and gigantic snow-capped mountains spread a range of hills, lakes and gorges, constituting undulation alpine prairie. The most magnificent pastoral view along the Qinghai-Tibet Railway is the famous Qiangtang or Changtang Grassland in north Tibet.
Train has become the major way to Tibet for travelers. As it is a long-distance trip, the service on the train is very important. In order to make passengers travel comfortably onboard, the train is equipped with air-condition, oxygen supply system and anti-radiation sightseeing windows.
The oxygen supply system is the most important. It is the key element to ensure passengers’ comfort and safety because 960km of the Qinghai-Tibet Railway is built on the area over 4,000 meters above sea level, which easily causes high altitude sickness.
Though the Qinghai-Tibet Railway starts from Xining, capital of Qinghai Province, its highlight is the section from Golmud to Lhasa. The lotal length of this railway is 1,956 km, 815 km of which is between Xining and Golmud and 1,142 km of which lies between Golmud and Lhasa. Over 80% of the Golmud-Lhasa section is at an elevation of over 4,000 meters above sea level, with the highest point of 5072 meters at the Tanggula Pass.
