Following theJuye Incident, theGerman army landed at Tsingtao in 1897. In 1898, theQing government signed theJiao'ao Concession Treaty with Germany, which made Tsingtao a German colony. This treaty also granted the German government the right to build theJiaoji Railway and develop the mineral deposits along the route.

Kaiser Wilhelm II was determined to make Tsingtao a "model colony" and a bridgehead for theGerman army in theFar East. As a result, German authorities built a number of factories in Tsingtao between 1900 and 1910.^[2] In October 1900, while building the Jiaoji Railway, German authorities began constructing the Shantung Railway Syfang General Repair Works (Hauptreparatur-Werkstätte Syfang der Schantung-Eisenbahn), which was under the Shantung Railway Company (Schantung-Eisenbahn-Gesellschaft), with a total investment of 1,587,000marks. It became China's third rolling stock factory afterTangshan andDalian.^[3] The factory was located near the Sifang Railway Station in Sifang Village, with more than 10,000 square meters of factory spaces and more than 400 workers, and was completed in 1902.^[4][5] Locomotive parts were imported from Germany and assembly was conducted by the Sifang plant. By 1914, a total of 1,148 locomotives, coaches, and wagons had been assembled or repaired.^[6]

In 1914, theFirst World War broke out, and Germany was occupied with war at the homefront.Japan and theUnited Kingdom took the opportunity and launched theSiege of Tsingtao. The Shantung Railway Syfang General Repair Works was damaged during the siege. In 1915, the Empire of Japan forced theRepublic of China government to accept itsTwenty-One Demands, which affirmed Japan's takeover of the German territories and railroad assets inShantung. The Syfang General Repair Works was renamed Shantung Railway Syfang Workshop, which was temporarily managed by theJapanese Army. In March 1915, the Japanese army in Tsingtao established the Shantung Railway Administration, which had five departments: general affairs, transportation, engineering, accounting and mining, and the Tsingtao Workshop.^[7] During the Japanese occupation, additional facilities such as sand casting factories, passenger wagon yards, wheel factories, copper casting yards were built, and the number of employees reached more than 1,500.^[8]

In 1938 theBeiyang government took over control of the rolling stock manufacturer but constant political turmoil left railway development on hold until 1949.^[9]

After 1949 the facility becameSifang Works and in 1952 produced China's first indigenous steam locomotive,August 1st, then through the 1960s and 1970s became a supplier toChina Railway passenger cars and later expanded to export markets by the 1980s.^[9]

Bombardier Sifang (Qingdao) Transportation Ltd was established in 1998 as a joint venture betweenBombardier Transportation (Germany) and Sifang Locomotive and rolling stock company limited as a company for the production of high speed trains and high quality coaches. This joint venture includes a new IS development named JOSS (joint venture operating system support)^[20]

Kawasaki Heavy Industries (KHI) co-operated with CRRC Sifang Co Ltd. in year 2009 to produce theC151A trains, the fourth generationMRT train forSMRT Trains, in Singapore. A total of 22 trainsets were built with 6 carriages each.

By 2010, half of the trainsets are completed, and testing was done in 2011 byKawasaki Heavy Industries, before full delivery in December 2011. These trains now serves theNorth South line &East West line in Singapore.

Another 78 cars (13 trainsets) ofC151A trains which in production to be delivered by 2014.^[21]

In 2012, KHI and CSR Sifang will collaborate to manufacture the new 168 cars (28 trainsets) ofC151B trains and will deliver from 2015 till 2017.^[21][22]

An additional 174 cars (29 trainsets) ofC151B trains were ordered in 2014 and will be delivered from 2017 till 2019 and a total of 57 trains but they have been reduced to 45 set as they announced and the first trainset was delivered in 2015, Another 12 set ofC151C trains are expected to be added by 2019 which were ordered in 2015.

In 2013, Kawasaki Heavy Industries (KHI) planned to sue CSR Sifang for patent infringement after their partnership was dissolved. KHI said it deeply regretted entering into the partnership. KHI subsequently dropped the action.^[23]

In 2014, LTA had ordered the new 364 cars (91 trainsets with 4 cars) ofT251 Trains with manufacture by KHI and CSR Sifang for futureThomson-East Coast line and will have fully automated and driverless trains, and also the first trains in Singapore to have 5 doors on each side and each carriage, These 91 new trains will deliver from 2018 onwards.

On 5 July 2016, a Hong Kong Based non-profit news organizationFactWire had broken the news of SMRT C151A suffering from multiple defects^[24] relating to Chinese-made materials and posted the entire investigative works inYouTube.^[25] and most of its claims are subsequently acknowledged by the rail operatorSMRT and the transport authorities inSingapore,Land Transport Authority. The entire issue has since generated a huge amount of controversies inHong Kong andSingapore with some rumors spreading in the Internet as well.
