Does the rainstorm affect the high-speed rail?

Heavy rain has an impact on the safety of high-speed rail operation, and it is not uncommon for motor trains and high-speed rail to be limited or stopped due to weather. The train outage is related to the rainstorm weather in China; Weather processes such as thunder and lightning and strong winds often bring tests to the normal operation of trains. Rain will not cause the EMU to stop. EMU trains will stop running only when there are severe weather such as thunderstorms and strong winds that may damage railway facilities and equipment.

Compared with aviation, waterway and highway traffic, railway traffic is indeed the least affected by the weather, but to ensure the safety of high-speed high-speed rail and bullet trains, the weather factor can not be ignored.

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, heavy rain may damage the subgrade; Thunderstorm activities may lead to train, railway communication and signal failures, laying a great hidden danger; Under high temperature in summer, the longitudinal pressure of rail increases. If measures are not taken in time, the high-speed train may have a rollover accident when passing.

Geological disasters caused by disastrous weather processes, the collapse of roads and bridges, and the damaged and collapsed facilities on both sides of the railway may all affect railway traffic.
