Will the high-speed rail be affected by the weather?

The high-speed rail will be affected by the weather. Severe weather such as strong wind, thunder and lightning, rainstorm, flood, hail, heavy snow, fog, extreme high and low temperature may affect the operation of high-speed rail and bullet trains and their subgrade, bridge, power grid and other facilities. Even if there is a drainage device on the railway track and tunnel, when the short-term rainfall is too large, heavy rain may damage the subgrade; Thunderstorm activities may lead to train, railway communication and signal failures, laying a great hidden danger.

Reasons for high-speed rail outage in blizzard days:

1, the speed of high-speed rail is generally very fast, but if it encounters extreme weather such as rain and snow. Then the probability of high-speed rail equipment failure will greatly increase. In addition, most high-speed trains are powered by the power grid. If the power grid fails in snowy days, the trains will also fail or even be damaged accordingly.

There are still many high-speed trains that will slow down when it snows again, if the situation is not serious. However, the high-speed train bus, like the bus, is characterized by short train interval and high departure rate. So if a train slows down at this time, the number of trains on other lines of the whole project will also decrease. It will reduce the transportation efficiency of the whole project a lot.
