What caused the high-speed rail to be delayed?

The delay of high-speed rail is caused by weather factors, equipment failure, line failure and other reasons.

1. Weather factors: For example, the rain and snow weather caused the railway tracks to cross too thick, which led to the abnormal operation of railway switches, which led to the delay of trains. In addition, severe weather such as freezing rain and blizzard will also cause large-scale delays of high-speed trains in some areas.

2. Equipment failure: Equipment failure of the high-speed rail itself, such as EMU failure, will also cause the train to be delayed. For example, the front EMU stops on the main line due to a fault, and the rear train can only wait for the dispatch to start, which will cause the rear train to be delayed.

3. Line failure: In addition to the failure of the vehicle itself, the failure on the line will also cause the high-speed rail to be delayed. For example, there are foreign objects on the railway track, or the railway signal system fails, which will affect the normal operation of the high-speed rail.

High-speed railway, referred to as high-speed railway for short, refers to a railway system with high design standards and high speed for the safe running of trains. The first high-speed railway system in the world is the Tokaido Shinkansen in Japan, which was completed and opened to traffic on 1964. According to the Code for Design of High-speed Railway issued by China National Railway Administration, high-speed railway refers to the newly-built passenger dedicated railway with a design speed of 250 km/h to 350 km/h and running the standard gauge of EMU trains.
