There is a typhoon in Shanghai today. Will the subway be suspended?

1. A series of problems caused by power outages. For example, the locomotive stops running, communication is blocked, and signal transmission disappears.

2. The dangers of the subway drainage system. The groundwater in many cities is very complex, and the drainage system cannot drain it out under special conditions. Especially when problems occur in the power supply system, it will endanger traffic safety such as subways and road culverts. Therefore, when a typhoon approaches, corresponding arrangements will always be made for transportation in special areas.

3. The ground section of the subway is directly affected by the typhoon. Many subways are not completely underground. There are periodic above-ground sections. Needless to say, the above-ground subway sections will be damaged by typhoons.

The subway is a system, not just the subway cars, but also the signaling system, power supply system, control system, and safety system in the station. These are closely related and intertwined. Therefore, in order to ensure the safe operation of the system, especially the signal system and control system that are interfered outdoors, temporary suspension or slow speed is necessary. ?

Safety first. Severe natural conditions such as typhoons will affect the normal operation of the subway. The suspension of Shanghai subway operation is the right arrangement. Although the subway suspension has brought inconvenience to people's lives, it is understandable. ?

These road sections are on the ground and most of them are in open areas in the suburbs. What if a street sign fell down or a tree fell on the track and the subway hit it? Wouldn't something big happen?

So sometimes such a series of problems are inevitable, and it would be better for all of us to pay more attention
