There are 5 different cars for the passengers, hard sleeping car, soft sleeping car, Seats car, dining car. There are 6 beds without a door for the hard sleeping car. The cars for the Tibet railway were newly built, which I think they are clean. One thing particular is that the cabins are all pressurized.
