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.
