Why is the high-speed rail delayed when it rains heavily?

1, heavy rain will make the track wet and the wheels will slip more easily. Rain may also reduce visibility, which is not conducive to observation. In order to ensure the safe operation of the high-speed rail, whether it is raining or snowing, the high-speed rail must run at a speed limit.

2. Sometimes, heavy rain rushes to the foundation, or the high-speed rail line breaks down, which will also cause the train to be delayed. The high-speed rail was delayed because the railway department took the initiative to take measures for the safety of passengers.

Sometimes heavy rain will cause natural disasters, such as floods, mudslides, ice and snow, typhoons and other irresistible natural disasters. In order to ensure the safe operation of the high-speed rail, whenever a natural disaster occurs, the high-speed rail must run at a limited speed or stop, which will easily lead to the delay of the train.

4. Heavy rain sometimes leads to equipment failure. Any mechanical equipment will break down, and high-speed rail is no exception. The failure of electronic equipment is also the reason why the high-speed rail stopped and was delayed.

High-speed rail has a high degree of automation and informatization. Although some key equipment has been fully backed up by the railway department, it is sometimes affected by equipment failures such as power failure and instantaneous switching. For the sake of safety, generally, EMUs will take the initiative to stop when they encounter equipment failure, and will not start again until the failure is eliminated.

Extended data:

When the high-speed rail was delayed due to heavy rain, the railway department launched an emergency plan to actively repair it, and some delayed trains gradually resumed operation.
