China Expands World’s Largest High-Speed Rail Network by 1,142km

China has added 1,142 kilometres of high-speed railway to its already world-leading network, opening four new sections across northern, central, northeastern and northwestern regions as it continues to strengthen links between major cities and less-connected areas.

The new sections began operations on September 28, connecting Xiong’an in Hebei Province with Shangqiu in Henan, Xi’an with Ankang in Shaanxi, Yichang with Xingshan in Hubei, and Harbin with Yichun in Heilongjiang. The openings extend a network that had surpassed 50,000 kilometres by the end of 2025, according to figures from China’s national railway operator.

The latest expansion includes a 552-kilometre route linking Xiong’an, the planned development area established to ease pressure on Beijing, with Shangqiu in central China. The new connection is expected to improve access between northern and central markets, with the fastest journey between its terminal cities taking about two hours and 27 minutes.

In the northwest, the 171-kilometre Xi’an–Ankang section crosses the Qinling Mountains and is designed for speeds of up to 350 kilometres per hour. Its opening reduces the rail journey between the two cities to approximately 45 minutes. The project also involved construction through challenging mountain terrain, underscoring the engineering demands of extending high-speed rail across China’s varied geography.

The other two sections add capacity and connections in central and northeastern China. The Yichang–Xingshan route links two major high-speed rail corridors, while the 318-kilometre Harbin–Yichun line extends high-speed services farther into the country’s northern reaches. The latter is expected to cut travel time between the two cities from about seven hours to roughly two, improving access to destinations in Heilongjiang Province.

The expansion comes amid sustained growth in demand for rail travel. China’s railway network recorded 3.71 billion passenger trips during the first nine months of 2026, a 4.8 per cent increase on the same period a year earlier and the highest total for the period, according to China State Railway Group. The network also carried more than 19 million foreign passenger trips, up 33.4 per cent year on year, reflecting growing use of the system by international visitors.

More broadly, China continues to invest heavily in its railway infrastructure. The sector recorded 601.2 billion yuan, equivalent to about US$89 billion, in fixed-asset investment during the first three quarters of 2026, up 1.3 per cent from a year earlier. Across the wider railway system—not only high-speed lines—1,625 kilometres of new railway routes entered service over the same period.

Beijing’s longer-term plan is to expand the high-speed network to 70,000 kilometres by 2035, organized around eight north–south corridors and eight east–west corridors. The intended system would link major cities, urban clusters and key economic zones, strengthening connections between regional economies and improving access to rail services.

China is also looking beyond the construction of new routes. A railway science and technology plan for 2026–2030 includes demonstration projects for high-speed train operations at 400 kilometres per hour and continued research into magnetic-levitation technology capable of reaching 600 kilometres per hour. These are research and development goals, not evidence that such speeds are already in routine passenger service.

The latest openings underline how China’s rail strategy combines network expansion with efforts to increase capacity, reduce journey times and connect more regions to major transport corridors. The scale of the system and the growth in passenger demand also place continued emphasis on delivering reliable services and ensuring that the benefits of faster rail connections extend beyond the country’s largest urban centres.
