The CRH1 EMU, also known as Hexie (simplified Chinese: 和谐号; traditional Chinese: 和諧號; pinyin: Héxié Hào; literally: "Harmony") is a high-speed train operated by China Railway and built by a joint venture between Bombardier Transportation and Sifang at Bombardier Sifang Power Transportation factory in Qingdao, Shandong Province, People's Republic of China. At the same time as ordering the Shinkansen-based CRH2A and the Pendolino-based CRH5A, the Chinese Ministry of Railways ordered Bombardier-based CRH1, specifically 20 CRH1A trainsets in June 2007 and an additional 20 CRH1A trains, each with eight cars that have total standard capacity of 670 people. The total value of the order is €560 million. In July 2010, a further 40 CRH1A eight-car trains were ordered. Variants CRH1A CRH1A and CRH1B are based on Bombardier's Regina family. The train was designed by Sifang and Bombardier jointly in Västerås, Sweden and originally named C2008. Each CRH1A set consists of eight cars, the first batch (CRH1-001A~CRH1-040A) including two first class coaches (ZY), 5 second class coaches (ZE) and 1 second class coach/dining car (ZEC).the second batch (CRH1-081A~CRH1-120A) including two first class coaches (ZY), one first class/second class coaches (ZYE), four second class coaches (ZE) and 1 second class coach/dining car (ZEC). The potential maximum speed of CRH1A is , but in fact the maximum speed of the initial 40 sets in operation is always restricted by the software of computer control system, so the maximum speed in service is . The first units (CRH1-001A) were delivered on August 30, 2006, the CRH1A sets started service from February 1, 2007 at the Guangzhou -Shenzhen Railway. In July 2010, the Chinese MOR ordered additional 40 sets of CRH1A, The designed top operating speed increased to , In September 2010, during test run at Qinshen PDL, top speed of CRH1-081A reach . From July 1, 2014, all CRH series EMU numbers have been changed. The original number is (CRH1—xxxA), and now it is changed to (CRH1A-1xxx). Production EMUs after that date are in accordance with the new regulations. CRH1A-A In September 2012, The MOR issued a revision in the Zefiro contract, which calls for the order of an additional 106 eight car Zefiro 250 (46 sets) and Zefiro 250NG (60 sets) train sets in lieu of the cancellation of the 16 car Zefiro 380 sets.
