The rail transit system has the obvious advantages of low operation energy consumption, small occupied area, light environmental pollution and the like, and is unique in a plurality of transportation modes.
The regional span of China is large, and rail trains need to adapt to complex and changeable running environments such as strong wind and sand, strong wind and snow and the like. In cold winter, the snow fall amount is large in parts of China such as northeast, northern Xinjiang and Qinghai-Tibet plateau, and a series of special problems are brought to rail transit construction and operation. The problem of snow and ice in the bogie area is solved, and the safe operation of the railway vehicle is particularly critical.
