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.
