Changchun Railway Vehicles
The first three trains were built in Germany by Siemens, and these imported trains were labelled CRH3A (CRH3-002A, CRH3-003A and CRH3-004A), different than the CRH3A-5218 developed independently and manufactured by CRRC Changchun Railway Vehicles in 2017, designed to operate at a cruise speed of 250 km/h (155 mph).
