    Zhengzhou-Xi'an Passenger Dedicated Line
    Source:CREC Date:2018年11月29日

    This project is an important part of the national medium- and long-term railway network planning. It started construction in 2005 and has a design length of 454 kilometers. CREC provides one-third of the survey and design services for the entire project, whose design speed is 350 km/h. The survey and design of this project is very difficult because it is located at the mountain sections and its geological conditions are extremely complicated.
