China Railway High-speed (CRH) is the high-speed rail service operated by China Railway. Hexie Hao (simplified Chinese: 和谐号; traditional Chinese: 和諧號; pinyin: Héxié Hào; literally: "Harmony") is the designation for rolling stock operated for this service. All trains had been marked "CRH", before being changed shortly afterwards to the Chinese characters "和谐号" on the centre of the head vehicles and the side of the walls of other vehicles. The introduction of CRH was a major part of the sixth national railway speedup, implemented on April 18, 2007. All high-speed trains in commercial use in China are named CRH . CRH1/2A/2B/2E/5 are expected to have a maximum speed of 250 km/h (160 mph), and CRH2C/3 have a maximum speed of 350 km/h (220 mph). The new trainsets CRH380A have a maximum test speed of 416.6 km/h (258.9 mph). The fastest trainset, CRH380BL, attained a maximum test speed of 487.3 km/h 302.8 mph).

High-speed rail services were first introduced in 2007 operating with CRH rolling stock. Those run on existing lines that have been upgraded to speeds of up to 250 km/h (160 mph) and on newer dedicated high-speed track rated up to 350 km/h (220 mph).

China Railway High-speed runs different electric multiple unit trainsets, the designs for which are imported from other nations and designated CRH-1 through CRH-5 and CRH380A(L), CRH380B(L), and CRH380C(L). CRH trainsets are intended to provide fast and convenient travel between cities. Some of the trainsets are manufactured locally through technology transfer, a key requirement for China. The signalling, track and support structures, control software, and station design are developed domestically with foreign elements as well, so the system as a whole is predominantly Chinese. China currently holds many new patents related to the internal components of these trains, re-designed in China to allow the trains to run at higher speeds than the foreign designs allowed. However, these patents are only valid within China, and as such hold no international power.

The trainsets are as follows:

CRH1A, B,E, CRH2A, B,E, and CRH5A are designed for a maximum operating speed (MOR) of 200 km/h and can reach up to 250 km/h. CRH3C and CRH2C designs have an MOR of 300 km/h, and can reach up to 350 km/h, with a top testing speed more than 380 km/h. However, in practical terms, issues such as maintenance costs, comfort, and safety make the maximum speed of more than 380 km/h impractical and remain limiting factors.
