China Railway High-speed

China Railway High-speed (CRH) is a high-speed rail service operated by China Railway in addition to China Railway's older Classic Rail services. The introduction of CRH series was a major part of the sixth national railway speedup, implemented on April 18, 2007. By the end of 2020, China Railway High-speed provided service to all provinces in China, and operated just under 38,000 km (24,000 mi) passenger tracks in length, accounting for about two-thirds of the world's high-speed rail tracks in commercial service.
