Why is the train at Wuhu Railway Station late today?

There are probably several reasons for the delay of the train: weather factors, human error, train dispatching control error, train route modification and so on. Let's start with the weather.

China's four "black" hubs. They are: xiang tang Hub in Nanchang, Jiangxi, Zhuzhou Hub in Hunan, Zhengzhou Hub in Henan and Guiyang Hub in Guizhou. These four black hubs all have the experience of scaring train drivers, because passing through these hubs will inevitably cause the train to be delayed. The reason is that the railway network of these railway hubs is complex, trains pass too many times, and passengers and goods are mixed. Especially in Zhengzhou, at the intersection of China's busiest Beijing-Guangzhou line and Longhai line, there is an average train passing through Zhengzhou hub every minute. With such a large traffic flow, there will be a large area delay if there is a slight problem in dispatching and commanding. Dispatching is generally based on the train schedule, to confirm which train to put first. However, if the train that should have been released first is delayed, it will inevitably affect the normal release time of other trains. Fortunately, after the transformation of Guiyang hub, the separation of passenger and cargo operations was realized, which greatly avoided the occurrence of later accidents. Wuhan hub has long realized the separation of passengers and goods, so there are few cases of trains being delayed in Wuhan hub.
