High-speed rail in China
High-speed rail in China is the country's network of passenger-dedicated railways designed for speeds of 250–350 km/h (155–217 mph). It is the world's longest high speed railway network and is also the most extensively used.
In mid-2018, HSR extended to 30 of the country's 33 provincial-level administrative divisions and almost reached 27,000 km (17,000 mi) in total length, accounting for about two-thirds of the world's high-speed rail tracks in commercial service. The HSR building boom continues with the HSR network set to reach 38,000 km (24,000 mi) in 2025.
The advent of high-speed rail in China has greatly reduced travel time and has transformed Chinese society and economy. A World Bank study found "a broad range of travelers of different income levels choose HSR for its comfort, convenience, safety and punctuality."
