Will the train stop in the heavy snow?

When encountering large-scale rain, snow and freezing weather in the northern region, in order to ensure the safety of passengers, the railway department will dynamically adjust the passenger train operation plan of some lines according to the weather impact, and take preventive measures such as slowing down, bypassing and stopping to actively avoid safety risks. Especially in some severely affected areas, such as Hunan and Jiangxi, heavy snow may cause some passenger trains to stop. The surrounding environment along the railway has great influence on wheel-rail adhesion, including leaves, plants, oil, water, ice and snow. When these pollutants are attached to the rail, the adhesion between the wheel and the rail will drop sharply, which will lead to the sliding of the locomotive wheel and the wear between the wheel and the rail. When necessary, the sand box can sprinkle sand to the driving wheel through the throat to increase the adhesion between the wheel and rail, thus increasing the traction. However, when the snow is too heavy, the train operation will be affected, causing the train to be delayed to varying degrees. In severe cases, the train will stop to ensure personal safety.
