Going to Lhasa by train, on the plateau, is the oxygen concentration the same inside and outside the car? Is the pressure the same?
No, the train to Lhasa is pressurized with oxygen. The train carriage bound for Lhasa is equipped with two oxygen supply systems to balance the oxygen concentration, temperature and pressure in the carriage. The configuration of each carriage is almost the same as that of an airplane, and there are two sets of oxygen supply systems: one is "decentralized" oxygen supply, which keeps the oxygen content of each carriage at a suitable level through the air in the hybrid air conditioning system; The other set is an independent oxygen inhalation interface. If the passenger needs more oxygen, he can breathe with the oxygen tube at any time.
