Air-conditioning System on Tibet Train

All the trains to Tibet are air conditioned and pressurized for the trains have to run through the mountain areas at high altitude. The air-conditioning in the Tibet train can keep the temperature in the train at a comfortable level so that passengers can enjoy the breathtaking scenery along the world's highest railway in a cozy environment. Of course, the other facilities, such as the Oxygen supply system and the pressurizer also contribute great to this comfortable environment.
