Abstract

The altitude difference along the western plateau railway is very large. The highest altitude of the whole line is more than 4000 meters, the lowest altitude is only a few hundred meters, the lowest temperature is lower than -30 °C, and the bridge-tunnel ratio is as high as 90 %. These special line conditions will lead to great changes in the basic resistance of rolling stock operation. According to the calculation formula of train dynamics, this paper analyzes the influence of these special environmental factors on the basic resistance of the train by adding altitude, temperature, tunnel and other factors. The results show that the basic resistance of the locomotives is closely related to altitude, temperature, tunnel and other factors. The basic resistance decreases with the increase of altitude and increases with the decrease of temperature. Compared with the open line in the plain, the altitude change in the western plateau will lead to a decrease of about 70% in the basic resistance of the open line, and the temperature change will lead to a decrease of about 17% in the basic resistance of the train operation. The basic resistance of the train running in the tunnel in the western plateau area will increase by about 133%.
