Recently, the launch ceremony for "Wujian No. 3", the first shield TBM on the northeast section of Zhengzhou Rail Transit Line 6 Phase I, was grandly held at Tonghuai Station, which is being constructed by Henan Wujian. The smooth launch of "Wujian No. 3" marks that the project has officially entered the shield tunneling construction stage for the running tunnels, opening a new chapter in the construction of the northeast section of Zhengzhou Rail Transit Line 6 Phase I.

The northeast section of Zhengzhou Rail Transit Line 6 Phase I runs along the southwest-northeast axis of Zhengzhou. It is of great significance for expanding Zhengzhou's rail transit framework, optimizing and improving the rail transit network and urban spatial layout, alleviating urban traffic pressure, improving the level of urban public transport services, and accelerating the construction of Zhengzhou as a national central city.
