Compared with arriving Lhasa by air, train travel is safer in terms of acclimatization. However, it is inevitable to talk about the altitude sickness when introducing the Qinghai-Tibet railway, for most of time it runs above 3500 meters. After checking in on the train, the attendant will ask you to fill a Passenger Health Declaration Form to declare that your health can adapt 3000 meters above high elevation travel.

The Tibet train has two oxygen supply systems; one is the individual oxygen supply system that works anytime when you need it and it is just under your seat or above your sleeper, very easy to get access to; the other is the central oxygen enrichment system that starts to work after the train arrives at stop of Golmud city which is 2815 meters above sea level, that is to say, after the train passing the stop of Golmud city, all the train cars will be oxygen-enriched. And individual supply is only used when extreme cases take place, yet this seldom happens.
