Why was the Beijing-Shanghai high-speed railway delayed on September 9, 2022?

1, the interval dispatching is difficult. At a certain time, the passengers are relatively concentrated and the passenger flow is dense, which makes it difficult for passengers to get on the bus, which may lead to the delay of passenger train departure; With a large number of passengers running, the railway transportation capacity is in a state of supersaturation, and the difficulty of train operation adjustment is obviously increased.

2. With the sudden increase of passenger flow, the railway runs in strict accordance with the operation diagram, and the inter-station stay time is stipulated. However, with the sudden increase of passenger flow, the boarding time will inevitably increase, which will lead to delays.

3. Railway equipment failure, such as line speed limit caused by line construction, accidents and equipment failure, locomotive failure and line switch damage caused by traction train operation error, etc.

4. Weather and geological reasons, such as bad weather, storm, snow, fog, road collapse and landslide, limit the speed of the line.
