All Tunnels on Yulinbei-Cenxidong Section of Nanning-Zhuhai High-Speed Railway Completed

 

  On August 12, the Tianxing No. 1 Tunnel, one of the most challenging control projects on the Yulinbei-Cenxidong section of the Nanning-Zhuhai High-speed Railway, was successfully completed. This milestone marks the full completion of all 22 tunnels in this section, opening up the way for ballastless track laying and other follow-up works, representing major progress in project construction.

  The Yulinbei-Cenxidong section has a mainline length of 84.759 kilometers and has now entered a critical final construction phase. Station buildings and "four electric" systems are advancing in an orderly manner, while ballastless track construction has begun. The line is expected to open next year, further improving transportation conditions in eastern Guangxi and driving the economic and social development of surrounding areas.
