en.Wedoany.com Reported - The Xi'an to Kang High-Speed Railway (Xi'an-Kang High-Speed Railway) initiated a speed test at the maximum test speed level on July 10, laying the foundation for subsequent operational tests. At 11:52 on the same day, after multiple rounds of gradual speed increase tests, the inspection train reached the target test speed of 385 km/h.

The Xi'an-Kang High-Speed Railway is a key component of the Baotou (Yinchuan)-Hainan and Beijing-Kunming corridors within China's "Eight Vertical and Eight Horizontal" high-speed railway network. The newly built main line spans approximately 171 kilometers, with a design speed of 350 km/h. The line starts from Xi'an East Station, crosses the Chan River and the Qinling Mountains, passes through Zhashui, Zhen'an, and Xunyang in Shaanxi Province, and connects to Ankang West Station. Along the route, there are six stations: Xi'an East, Niubeiliang, Zhashui West, Zhen'an West, Tongmu, and Ankang West.

The gradual speed increase test is a critical phase in the integrated commissioning and testing of high-speed railways. According to the test plan, the operating speed is progressively increased in stages.

The inspection train must gradually increase its operating speed until it reaches 110% of the line's design speed, comprehensively verifying the safety performance, operational stability, and system compatibility of equipment such as tracks, power supply, signaling, and communications under high-speed conditions.

This speed test at 385 km/h utilized a high-speed comprehensive inspection train equipped with a full set of professional testing equipment. During operation, it simultaneously conducted a comprehensive dynamic "check-up" of all line equipment, including tracks, overhead contact lines, and communication signals.

According to the integrated commissioning and testing plan, the next step will involve gradual speed increase tests with coupled EMU trainsets to further verify equipment compatibility and reliability under coupled operation conditions, providing support for subsequent full-line through tests and running chart parameter testing.

Once the Xi'an-Kang High-Speed Railway 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. This will significantly shorten the spatial and temporal distance between the Guanzhong city cluster and the Qinba mountainous area in southern Shaanxi, playing an important role in supporting comprehensive rural revitalization and promoting high-quality local economic and social development.
