Does foggy weather affect high-speed rail?

Generally, high-speed rail can operate normally in foggy days.

Fog weather has little effect on the operation of high-speed trains, but sometimes in order to ensure the safety of operation, some trains may slow down in some sections, but the delay time is not long, which basically does not affect passengers' travel.

High-speed rail is a rail transit. There is a track below, so it can only travel in the track, and it is not necessary to control the direction like a car.

Moreover, the high-speed rail is closed and other vehicles and personnel are not allowed to enter. Modern trains rely more on the command of computer systems and dispatchers to judge whether there are obstacles ahead, so they can run normally in foggy days.

Extended data:

The weather is bad, and the high-speed train is going to stop;

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.
