China Opens Four High-Speed Rail Lines at Once

China opened four high-speed rail lines simultaneously on September 28, adding more than 1,100 kilometers of new track across the country’s north, northwest, central and northeast regions in a coordinated push to densify its national high-speed network. The lines — spanning Shaanxi, Hebei, Shandong, Henan, Hubei and Heilongjiang — launched just ahead of the National Day holiday and represent the latest step in Beijing’s “Eight Vertical, Eight Horizontal” (八纵八横) rail master plan.

According to Xinhua, the four lines extend the backbone grid that is now about 84% built and has pushed China’s high-speed rail operating mileage past 50,000 kilometers.

The Four Lines

The Beijing-Hong Kong high-speed railway’s Xiongan-Shangqiu section is the longest of the four at 552 kilometers with a design speed of 350 km/h. Running south from Xiongan Station through Hebei, Shandong and Henan to Shangqiu, it carries up to 64 trains a day and cuts Xiongan-Shangqiu travel to as little as 2 hours 27 minutes, per CNR. Sixteen stations line the route, most of them newly built, and the segment forms one “vertical” of the national grid, supporting the Beijing-Tianjin-Hebei coordination strategy and the Xiongan New Area.

The Xi’an-Chongqing line’s Xi’an-Ankang section adds 171 kilometers at 350 km/h across the Qinling Mountains. Xi’an-Ankang now takes 45 minutes, bringing high-speed rail to Zhashui, Zhen’an and Ankang for the first time and strengthening the Guanzhong region’s links to southern Shaanxi.

The Yichang-Xingshan line, 101 kilometers long and 94.4% tunnel, connects the Shanghai-Chongqing-Chengdu corridor with the Zhengzhou-Chongqing corridor. It slashes Wuhan-Chongqing travel from 4 hours 56 minutes to 3 hours 54 minutes. As the Yichang municipal government reported, the line strings together Hubei’s “Shennongjia-Wudangshan-Three Gorges” tourism corridor, linking seven world-class landmarks and 12 national 5A scenic areas.

The Harbin-Yichun line, China’s northernmost high-speed railway, runs 318 kilometers at 250 km/h. It cuts Harbin-Yichun travel from roughly seven hours to 1 hour 46 minutes and brings Suihua and Yichun into the high-speed era. It is the first Chinese line to cross a high-latitude, high-cold island permafrost zone, requiring double-layer casing foundations extending six to seven meters below the permafrost.

A National Grid Nears Completion

The “Eight Vertical, Eight Horizontal” network — defined in China’s Medium- and Long-Term Railway Network Plan — comprises eight north-south and eight east-west corridors with a planned main-corridor scale of about 45,000 kilometers. During the 14th Five-Year Plan, high-speed rail mileage rose from 37,900 kilometers to 50,400 kilometers, described by officials as the world’s largest and most advanced high-speed rail network.

People’s Daily via gov.cn reported that national fixed-asset investment in transportation reached 1.82 trillion yuan from January to July 2026, with major projects including the Sichuan-Tibet Railway and the Three Gorges water transport channel under construction. The report also noted that the CR450 high-speed trainset’s research and testing are in their final phase.

Beyond the Tracks: Economic and Regional Impact

The openings are framed as more than engineering milestones. Yuan Baohua, deputy director of the construction department at China Railway Group, and other officials told Xinhua the lines are intended to smooth domestic circulation, promote coordinated regional development and serve higher-quality travel.

For Heilongjiang, the Harbin-Yichun line advances the province toward full prefecture-level high-speed coverage: 10 of its cities are now connected, with only Heihe still lacking high-speed rail. Liaoning achieved full coverage in September 2025, while Jilin is targeting completion of its final link by the end of the 15th Five-Year Plan.

The economic stakes are visible along the route. Yichun, a forest city of about 802,000 people, recorded more than 20 million tourist visits and over 20 billion yuan in tourism revenue in 2025, up 36% and 39% year-on-year. As Time Weekly noted, the high-speed link pulls Yichun into Harbin’s “two-hour economic circle,” but analysts caution it could also accelerate the outflow of talent and consumption from smaller cities toward larger hubs.

Zhang Lixin, a professor at the Heilongjiang Provincial Party School, argued the line will promote cross-regional flows of people, business and information, driving counties along the route to shift “from single-point resource development to cross-regional industrial coordination.”

What to Watch

The openings coincide with the start of China’s 15th Five-Year Plan, whose 2030 targets include completing 95% of the national transport network backbone, achieving one-hour commuting for 75% of major metro-area populations, and building 25,000 kilometers of digital-intelligent and 35,000 kilometers of zero-carbon transport corridors.

The coming years will test whether the new lines deliver on their promise. For smaller cities along the routes, the central question is whether faster access to major hubs translates into sustained tourism, investment and jobs — or simply makes it easier for people and spending to flow outward. China’s rail buildout is far from finished, but the four lines opened on a single day offer a clear measure of how quickly the network is maturing.
