The north-south Taiyuan - Zhengzhou line has a maximum design speed of 250km/h, enabling an end-to-end journey time of around 2 hours. The new line passes through the Taihang Mountains.
The new line from Zhengzhou Xinzheng Airport to Zhengzhou South is 10.9km long. Zhengzhou South station is the third major station to open in the city and has 16 platforms and 32 tracks, although the 483,000m2 station building is still under construction.
Meanwhile, trial operation on the final Beijing - Chengde section of the Beijing - Shenyang - Harbin high-speed line began on December 11. When the line opens, the Beijing - Shenyang journey time will be reduced to 2h 30min.
