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

Of course. High-speed rail refers to a railway system with high design standards and fast train speed. Its concept is not limited to tracks, let alone trains. High-speed rail has different regulations in different countries, different times and different scientific research and academic fields. High-speed railway is a railway system with high design standard and fast train running speed. It can also be operated in rainy days, and it will not have any impact on the normal operation of high-speed rail. Because there are lightning protection facilities on the high-speed rail, the elevated rail and ballast bed can resist the impact brought by rainy days, so there will be no water on the rail. Only when the accumulated water in a certain section reaches the top of the rail surface will the operation of that section be stopped and the vehicle can continue to operate in other sections. High-speed rail can't leave in heavy rain. Severe weather such as strong wind, thunder and lightning, rainstorm and flood, hail, snow and fog, and extreme high temperature and low temperature weather may have an impact on the operation of high-speed rail, motor trains and their subgrade, bridges, power grids and other facilities. Even if there is a drainage device on the railway track and tunnel, when the short-term rain intensity is too large, the heavy rain may damage the subgrade, and the thunderstorm activity may lead to the communication and signal failure between the train and the railway, laying a great hidden danger.
