High-speed rail in China
The high-speed rail (HSR, Chinese: 高铁; pinyin: Gāotiě) network in the People's Republic of China (PRC) is almost entirely owned and operated by the China State Railway Group Co. under the brand China Railway High-speed (CRH), including HSR trains, tracks, and services. China's high-speed rail network is the world's longest and has the highest ridership, as it accounts for roughly two-thirds of the world's total and has expanded to more than 50,000 km in operational length. The HSR network encompasses newly built rail lines with a design speed of 200–380 km/h (120–240 mph).
Since the mid-2000s, China's high-speed rail network has experienced rapid growth. CRH was introduced in April 2007, with the Beijing-Tianjin intercity rail, which became fully operational in August 2008, being the first passenger-dedicated HSR line. Currently, the HSR extends to all provincial-level administrative divisions and the Hong Kong SAR with the exception of Macau SAR.
