Can the high-speed rail run normally when it snows?

The website of Railway 12306 shows that light snow and medium snow have little influence on high-speed rail. If it is heavy snow or blizzard, it may affect the punctual operation of the high-speed rail. Snowfall will affect the high-speed rail. In fact, the low temperature caused by snowfall will freeze catenary, turnout and other facilities. The icing of catenary will affect the power supply, and the icing of turnout will affect the running direction of the train. In winter, there are many bad weather, such as rain and snow. Railways, civil aviation and other departments suggest that passengers should pay attention to the weather conditions at the departure point and destination, and then respond reasonably according to their own travel arrangements. In addition, passengers are advised to take the early high-speed train as much as possible. In this way, even if the weather is bad, there is still room for returning and changing the visa. Try not to choose the last high-speed train.
