Xi'an–Shiyan high‑speed line enters final testing: 256 km, 350 km/h, 90% bridges and tunnels, three hours to Wuhan
Test train 55302 departed from Xi'an East at 08:39. The new line cuts through the Qinling Mountains, where bridges and tunnels account for over 90% of the route. Once opened, Xi'an–Shiyan travel time will drop to one hour, Xi'an–Xiangyang to about two hours, and Xi'an–Wuhan to just three hours. The line will become a key link in the fast passenger corridor between northwest and central China.
As reported by CCTV+, full‑scale trial operation began on Tuesday for the high‑speed railway connecting Xi'an (Shaanxi Province) and Shiyan (Hubei Province). At 08:39, test train 55302 departed from Xi'an East on the main line toward Shiyan East. Trial operation simulates real operating conditions to test system performance before official opening.
Wang Hongtiao, deputy director of the transport department of the Xi'an Railway Bureau, said: "By checking train running times and equipment performance, we will calibrate and verify all theoretical parameters against on‑site conditions, ensuring safe and punctual future operations." The Xi'an–Shiyan high‑speed line starts at Xi'an East, passes through Xi'an and Shangluo in Shaanxi, and Shiyan in Hubei, connecting to the existing Wuhan–Shiyan HSR at Shiyan East. The new line is about 256 kilometres long with a design speed of 350 km/h.
Fu Wei, chief engineer of the infrastructure section of Xi'an HSR, noted: "The entire line runs through the Qinling Mountains, with extensive bridge and tunnel sections. Bridges and tunnels account for more than 90% of the total length. We strictly followed quality standards, and all track indicators meet operational requirements for 350 km/h." This line is a key part of China's national high‑speed rail network. At its northern end, it connects to the Xi'an–Yan'an and Xi'an–Ankang HSRs, as well as trunk lines such as the Xuzhou–Lanzhou HSR. At its southern end, it integrates smoothly with the existing Wuhan–Shiyan HSR, forming a fast passenger corridor between Xi'an and Wuhan.
The Xi'an–Shiyan HSR is part of China's "Eight Vertical and Eight Horizontal" national rail plan. The Qinling Mountains are a natural barrier dividing northern and southern China. Building a 256‑km line with over 90% bridges and tunnels required advanced engineering solutions. Once operational, travel time from Xi'an (the ancient capital and Silk Road starting point) to Wuhan (a major transport hub in central China) will drop from the current 5–6 hours to just 3 hours, boosting regional economic integration.
For centuries, the Qinling Mountains divided north and south China. Today, trains pass through them in minutes, diving into tunnels and soaring over viaducts. Ninety percent of the journey is through rock and above ravines. Engineers have turned an insurmountable ridge into a high‑speed corridor. As the test train accelerates to 350 km/h, it carries not just passengers — it bridges cultures, markets and destinies. One hour to Shiyan, three hours to Wuhan — this is not just a schedule. It is a new rhythm for millions of people, for whom the mountains are no longer an obstacle.
