China Railways

High-speed rail (HSR) in China is officially defined as passenger-dedicated railways designed to carry multiple unit trains at speeds of 250–350 km/h (155–217 mph). Certain use freight and passenger rail lines, that can be upgraded for train speeds of 250 km/h, with current passenger service of at least 200 km/h (124 mph), are also considered high-speed rail. The country’s HSR network, which in 2016 extended to 29 of the country’s 33 provincial-level administrative divisions and exceeded 22,000 km (14,000 mi) in total length, accounted for about two-thirds of the world’s high-speed rail tracks in commercial service. The world’s longest HSR network is also the most extensively used, with 1.44 billion trips delivered in 2016.

HSR trains, track and service are owned and operated by the China Railway Corporation. The China Railway High-speed (CRH) high-speed train service was introduced in April 2007 featuring high-speed train sets running at 250 km/h on upgraded track. The Beijing-Tianjin Intercity Rail, which opened in August 2008 and could carry high-speed trains at 350 km/h (217 mph), was the first passenger dedicated HSR line.

High-speed rail developed rapidly in China over the past 15 years thanks to generous funding from the Chinese government, especially the economic stimulus program during the Great Recession. The HSR building boom has nevertheless continued with the HSR network set to reach 38,000 km (24,000 mi) in 2025 and 45,000 km (28,000 mi) in the longer term.

China’s early high-speed trains were imported or built under technology transfer agreements with foreign train-makers including Alstom, Siemens, Bombardier and Kawasaki Heavy Industries. Since the initial technological support, Chinese engineers have re-designed internal train components and built indigenous trains manufactured by the state-owned CRRC Corporation.

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.”

Notable HSR lines in China include the Beijing–Guangzhou High-Speed Railway which at 2,298 km (1,428 mi) is the world’s longest HSR line in operation, and the Shanghai Maglev, the world’s first high-speed commercial magnetic levitation line, whose trains run on non-conventional track and reach a top speed of 430 km/h (267 mph)
China HSR are also currently being implemented in the likes of Indonesia as well as Thailand
