Propagation on plateau railway has its own features, because of low pressure, permafrost and so on. The analysis of frequency characteristics of the radiation noise and noise propagation is based on the operation of diesel locomotive in the Lhasa –Shigatse Railway. According to the test, the distribution characteristics of the radiation noise frequency spectrum and noise propagation under different speeds (100km/h~132km/h) in operation of the train are obtained,and these conclusions could provide a basis on noise control of plateau railway.
