How big a typhoon will cancel the high-speed rail?

When the typhoon reaches 10 and above, the high-speed train will stop.

This is because typhoons of 10 and above are very strong and may pose a serious threat to the safety of high-speed rail lines and trains. In this case, high-speed rail operators will take preventive measures to suspend the operation of high-speed trains to ensure the safety of passengers and staff.

However, for strong winds of magnitude 7-8, the normal operation of high-speed trains will not be greatly affected. In this case, the high-speed rail operator will take corresponding measures according to the road conditions and weather conditions, such as speed limit or speed reduction, to ensure the safety and stability of the train. High-speed rail operators attach great importance to the influence of weather factors on train operation, and will make corresponding decisions according to the typhoon level and specific conditions.

In addition to severe weather conditions such as typhoons, high-speed trains may also be stopped due to the following circumstances:

1. Natural disasters: Besides typhoons, earthquakes, floods, rainstorms and other natural disasters may also cause the high-speed rail to stop running. These disasters may cause serious damage to railway lines and facilities, making trains unable to operate normally.

2. Unexpected events: emergencies such as fire and explosion may lead to the shutdown of high-speed rail. In order to ensure the safety of passengers and staff, the high-speed rail operator will decide whether to stop the train according to the situation.

3. Equipment failure: If the high-speed train or related equipment fails, the train may stop running. This includes signal system failure, power supply problem, locomotive failure, etc. In this case, maintenance and repair work must be carried out until the problem is solved.
