With the continuous expansion of high-speed rail lines in China, high-speed trains are operating in increasingly complex and changing environments, facing challenges such as strong winds and heavy snow. When high-speed trains operate in high-altitude areas, they may collide, deposit, and adhere to key components, forming snow, directly reducing traction, shock absorption, braking and other performance, affecting high-speed trains’ comfortable and operational safety, and bringing many difficulties to railway construction and operation. This paper is based on wind tunnel experiments using the silk thread method to observe the streamline flow direction in the bogie area. Experiments have shown that key parts of the bogie are susceptible to impact and form snow, while snow is less likely to form on the leeward side and above the bogie.
