en.Wedoany.com Reported - On the morning of June 27, the 57611 special inspection train departed from Xi'an East Station, traversing the Qinling Mountains towards Ankang West Station, marking the official entry of the newly built Xi'an to Ankang High-Speed Railway (Xi'an-Ankang HSR) into the joint commissioning and testing phase, with the countdown to full operation underway.
The Xi'an-Ankang HSR is a key component of the "Eight Vertical and Eight Horizontal" high-speed rail network's Baotou (Yinchuan)-Haikou corridor and the Beijing-Kunming corridor. The newly built main line spans approximately 171 kilometers, with a designed speed of 350 km/h.
The line starts from Xi'an East Station, crosses the Chan River and the Qinling Mountains, passes through Zhaoshui, Zhen'an, and Xunyang in Shaanxi Province, and connects to Ankang West Station. The entire line includes six stations: Xi'an East, Niubeiliang, Zhashui West, Zhen'an West, Tongmu, and Ankang West.
The Xi'an-Ankang HSR traverses the Qinling Mountains, featuring complex geological conditions. The bridge-tunnel ratio exceeds 90%, making construction highly challenging. Since construction began in June 2021, all participating units have continuously deepened the creation of high-quality projects. Currently, all tunnels along the line have been completed, all bridge main structures are finished, track laying has been successfully concluded, and the "four electrical systems" integration project has been installed and debugged. The overall engineering conditions meet the requirements for joint commissioning and testing.
Joint commissioning and testing is a critical step in transitioning a high-speed railway from the construction phase to the operational phase, akin to conducting a "full-body checkup" for the line. During this phase for the Xi'an-Ankang HSR, railway authorities simulate operational conditions to comprehensively test, verify, and optimize the track, subgrade, bridges, tunnels, power supply, signaling, communication, and customer service systems, as well as their interface compatibility. This process helps identify and rectify equipment issues in a timely manner, providing essential technical support for the line's opening.
As the lead entity for the joint commissioning and testing work, China Railway Xi'an Group Co., Ltd. has effectively fulfilled its primary responsibilities by coordinating efforts among construction, design, and construction units. It has formulated an implementation plan for the joint commissioning and testing, established a command center with multiple specialized working groups, and clarified work responsibilities, safety management requirements, and technical support measures for each phase.
Once the Xi'an-Ankang HSR is completed and operational, the fastest travel time between Xi'an and Ankang will be reduced from the current approximately 3 hours to under 1 hour, significantly shortening the spatial and temporal distance between the Guanzhong city cluster and the Qinba mountainous region in southern Shaanxi. This will play a vital role in supporting comprehensive rural revitalization and promoting high-quality economic and social development in the region.
