As of 2025, China had the longest high-speed rail network in the world.
China’s network exceeded 50,000 kilometers of operating high-speed railway by the end of 2025, making it dramatically larger than the systems of Spain, France, or Japan. The network links most major population centers and forms a national grid of north–south and east–west corridors rather than a single continuous route.
The expansion accelerated after the early 2000s. China opened its first high-speed railway in 2003 and then invested heavily in dedicated passenger lines, large stations, bridges, tunnels, and rolling stock. By the end of 2024, the network had already reached about 48,000 kilometers, with a further expansion target of roughly 60,000 kilometers by 2030.
A common mix-up is treating high-speed rail as a measure of train speed alone. Comparisons generally count operating high-speed railway lines, often including routes designed for speeds of 200 km/h or more. China’s system also includes trains capable of 350 km/h on selected corridors, while many lines operate at lower speeds depending on geography, traffic, and infrastructure.
