This paper introduces the experimental conditions of the modified oxygen supply equipment for passenger cars on the Qinghai-Tibet Railway over the plateau and Qinghai-Tibet line. Plateau tests showed that the oxygen generator reached the original design oxygen concentration index (23%), but to adapt to the use of the environment of the Qinghai-Tibet line, the oxygen concentration in the car need to be increased to 24% or more.
