Overview
CRRC Qingdao Sifang Co., Ltd. is a core subsidiary of CRRC, specializing in the R&D and manufacturing of high-speed EMUs, intercity EMUs, and metro vehicles. Located in Qingdao, it is a leader in China's high-speed railway equipment and exports to many countries.
History
The industrial lineage of CRRC Qingdao Sifang begins with the construction of the Shantung Railway Syfang General Repair Works in 1900. The workshop was established near Sifang railway station in Qingdao while the German-administered railway network in Shandong was being developed. Completed in 1902, it was intended to repair and assemble railway equipment and became one of the earliest major rolling-stock factories in China. Early production relied partly on locomotive components imported from Germany, with assembly and repair performed locally. The First World War brought military conflict to Qingdao and damaged the works. After Japan assumed control of German railway assets in Shandong, the facility was reorganized as the Shantung Railway Syfang Workshop. Japanese administrators expanded the site with facilities for sand casting, wheels, copper casting, and passenger-car work. The workforce grew substantially, but the factory’s development was repeatedly affected by changes in political control and instability in China. After 1949 the plant was reorganized as Sifang Works and became part of the state railway-industrial system. In 1952 it built the August 1st steam locomotive, regarded in the supplied reference material as China’s first domestically produced steam locomotive. Through the 1950s, 1960s, and 1970s, the works produced locomotives, passenger coaches, diesel-hydraulic locomotives, diesel multiple units, and other equipment for China’s railway network. The company’s capabilities broadened from repair and assembly toward integrated design and serial manufacture. From the 1980s onward, Sifang developed export activity and began participating in international technology cooperation. A major step came in 1998 with the creation of Bombardier Sifang Transportation, a joint venture intended to manufacture high-speed trains and premium passenger coaches in China. The partnership contributed to the production of CRH1-family trains and other high-speed equipment. Sifang also entered a long-running cooperation with Kawasaki Heavy Industries, supplying rail vehicles for Singapore’s Mass Rapid Transit system and participating in other programs. China’s high-speed railway build-out made Sifang one of the country’s most prominent train manufacturers. The company participated in CRH2 production and subsequently developed or manufactured CRH380A and CR400AF train families. These programs supported the expansion of high-speed passenger services across China and strengthened the company’s expertise in aerodynamic train design, lightweight structures, traction systems, passenger interiors, and high-volume production. Sifang’s urban-transit business expanded at the same time. Its metro vehicles have been supplied to numerous Chinese cities, including Beijing, Guangzhou, Zhengzhou, Chengdu, Shenyang, Tianjin, Qingdao, Shenzhen, and Chongqing. Overseas work has included Singapore MRT trains, Hong Kong urban and airport-related vehicles, and projects in Latin America, South Asia, and the Middle East. The company has also supplied coaches and multiple-unit trains for conventional and regional railways. The company’s international partnerships have not been without controversy. Kawasaki considered legal action after its cooperation with Sifang ended, citing alleged patent infringement, although the action was not ultimately pursued. In 2016, reporting on alleged defects in Singapore’s C151A trains produced significant public scrutiny of the trains’ materials and manufacturing quality. These episodes illustrate the technical, legal, and reputational challenges associated with large cross-border rolling-stock programs. In the 2010s and 2020s, Sifang continued to broaden its product and research portfolio. It worked on intercity CRH6 vehicles, Fuxing high-speed trains, monorail prototypes, light-rail vehicles, and overseas trainsets derived from Chinese platforms. The KCIC400AF used on the Jakarta–Bandung high-speed railway is derived from the CR400AF platform. The company also participated in overseas tram, commuter, and passenger-car projects. As a CRRC subsidiary, it remains a core manufacturing and technology platform within China’s railway-equipment industry.

Products and positioning
A large-scale, engineering-led rolling-stock manufacturer positioned around high-speed rail, urban mass transit, domestic railway supply, and international vehicle programs.
High-speed electric multiple unit
CRH2
The CRH2 is a high-speed electric multiple-unit family associated with Sifang’s cooperation with Kawasaki Heavy Industries. It became one of the important train platforms used during the expansion of China’s high-speed railway network and helped establish Sifang’s large-scale experience in high-speed train production.
High-speed electric multiple unit
CRH380A
The CRH380A is a high-speed train family developed and manufactured by Sifang for China’s high-speed rail system. It represents the company’s progression from technology cooperation toward domestically developed high-speed train platforms and has been used for high-frequency intercity and long-distance passenger services.
High-speed electric multiple unit
CR400AF
The CR400AF is a Fuxing-series high-speed train platform manufactured by Sifang. It is designed for China’s modern high-speed railway network and forms the basis for derivative international applications, including the KCIC400AF trains used on the Jakarta–Bandung high-speed railway.
