Will the fog affect the high-speed rail

The fog will not affect the high-speed rail.

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.

High-speed railway is an overhead closed system, and its running is mainly completed by automation system. Theoretically speaking, train drivers have no restrictions on the visibility ahead and can achieve "blind driving".

Strong fog mainly affects the power system of high-speed railway, especially fog-haze will cause "fog flash", and charged ions will breakdown insulators, which will lead to train power system tripping and power failure and affect train operation. "Fog flash" generally occurs when the train starts to leave the station, and "Fog flash" generally does not occur on the moving train.

Reasons for high-speed rail shutdown

1. Weather factors: Bad weather, such as heavy rain, heavy snow, smog, etc., may affect the safe operation of the high-speed rail, leading to the suspension of the high-speed rail.

2. Geological disasters: natural disasters such as earthquakes, floods and mudslides. It may lead to damage to the high-speed rail line, thus stopping the operation.

3. Equipment failure: such as train failure, signal failure and track failure. It may cause the high-speed rail to fail to operate normally and need to be shut down for maintenance.

4. Insufficient passenger flow: If the passenger flow of a high-speed rail is too small, it may lead to the suspension of the high-speed rail to optimize the transportation capacity.

5. Sudden accident: If passengers smoke in the car and the train suddenly brakes, it may also lead to the suspension of the high-speed rail.

6. Policy factors: For example, during the epidemic, in order to reduce the flow of people, some high-speed rail lines may be stopped or the number of trains may be reduced.
