The Xingang Jiangbei Railway is a freight railway planned by China's four vertical and four horizontal railway lines. It is also an important railway collection and distribution channel for Wuhan Xingang, the core port of the shipping center in the middle reaches of the Yangtze River in Wuhan. It can be connected with the major arteries of Beijing-Guangzhou and Beijing-Kowloon railways, which is of great significance to the construction of Wuhan's shipping center in the middle reaches of the Yangtze River.Editor/Ma Xue
