On August 7, reporters learned from Zhengzhou Metro Group that the northeast section of Line 6 Phase I has entered the no-load trial operation stage. The northeast section of Line 6 Phase I is a key urban rail transit trunk line covering Zhengzhou's southwest-to-northeast axis, with transfers to Lines 1, 2, 3, 4, and 5, as well as Lines 7 and 8 under construction.

At present, the main structures of all stations, running tunnels, cross passages, and track installation along the entire line have been completed, and no-load trial operation is underway; decoration and HVAC/electrical installation are 89% complete, overall electromechanical system installation and commissioning is 74% complete, and road restoration is 70% complete. The northeast section of Line 6 Phase I is progressing smoothly overall, and Zhengzhou Metro Group is making every effort to advance the project schedule.

The northeast section of the project is a key urban rail transit trunk line covering Zhengzhou's southwest-to-northeast axis.
