CRRC Dalian Co., Ltd. (formerly known as Dalian Locomotive and Rolling Stock Works), originally founded in 1899, is a national key large-scale enterprise which has a history of over 100 years. In the late 19th century, Dalian was colonized by the Russian and Japanese imperialists successively owing to the corrupt and incompetent Qing government. On March 27, 1898, Russia gained the access to lease Dalian and Lushun by forcing the Qing government to sign the "Sino-Russian Treaty to Rent LD" and won the privilege to build the Chinese Eastern Railway branch lines. The construction of the Eastern Railway Locomotive Manufacturing Plant (the former name of Dalian Works) was started in July 1899 and completed in 1901. The site of the plant now is located to the east by north of Victory Bridge in Zhongshan District, Dalian. In1903, the Chinese Eastern Railway and its Locomotive Manufacturing Plant started operation. Later the South Manchuria Railway Company took over the plant on April 1, 1907 and on July 8, 1908 it decided to relocate the plant to the new site, the northern Shahekou in outskirts of Dalian (the nowadays site) for reconstruction. Until August, 1911 the whole plant moved away and renamed as Manchuria Railway Shahekou Plant. Since then, the factory staff shared bitter hatred against the colonial invaders and jointly resisted foreign aggression with arduous struggles for nearly half a century. 
    When Japan surrendered on August 15, 1945, Shahekou Plant of the South Manchuria Railway Company was under Soviet control according to the "Sino-Soviet Treaty of Friendship and Alliance" since Soviet troops occupied in September, the plant was renamed as Zhongchang Railway Dalian Factory. May 1, 1950, the factory was transferred entirely to the Chinese government for independent operation according to the “Agreement about Chinese Changchun Railway, Lushunkou and Dalian” signed by Chinese and Soviet government. The factory was attributed to the Repair Department of Ministry of Railways (MOR) of Chinese Central People's Government, soon after the Manufacturing Department of MOR was established so the factory was managed by the Manufacturing Department of MOR and renamed as Dalian Locomotive and Rolling Stock Manufacturing Works. The Works was put under the MOR and led by the General Administration of Locomotive and Rolling Stock Works on August 22, 1953, renamed as the MOR Locomotive and Rolling Stock Manufacturing Works. In August, 1970 the Ministry of Railways amalgamated with the Ministry of Transportation, so the Works was belong to the Industry Department of the Ministry of Transport (MOT). In April 1975 the MOR and MOT were separated, so the Works returned to the Industry Department of the MOR (later renamed as China Railway Locomotive & Rolling Stock Industry Corporation) and renamed as Dalian Locomotive and Rolling Stock Works on March 23, 1994. The Works belong to China National Railway Locomotive & Rolling Stock Industry Corporation in September, 2000. CNR Dalian Locomotive & Rolling Stock Co., Ltd. founded by reorganization on December 29, 2003. After that, the company has become a wholly-owned subsidiary of CNR since June 26, 2008. CNR accomplished overall listing on December 29, 2009 at SSE. On September 25, 2009, a groundbreaking ceremony took place on Dalian Locomotive Lushun production base. On March 31, 2012, CNR modern trams project officially settled in Zhuhai; on December 19, 2014, the base for key components of big axle load locomotive in Lushun started construction.CRRC Corporation Limited was formally established on June 1, 2015 and CRRC Group was formally established on September 29 in the same year, CRRC Dalian Co, . Ltd entered the new course of development .
    Since the foundation of the People’s Republic of China, the Company has successively experienced six large scale technology transformations and step by step turned into a large scale enterprise being able to design and manufacture high-level rail transportation equipment independently from an old works that could only repair steam locomotives. In September, 1956 the company successfully designed and manufactured China’s first main line steam locomotive, filled the blank in domestic locomotive industry. The company had been designed and manufactured over 10 types of steam locomotives in total number of 977 units, accounted for 44% of total output with the same term in China till it stopped to produce steam locomotives in 1961. In September, 1958 the Company successfully self-designed and manufactured China’s first mainline diesel locomotive. In 1965 the Company realized a historic transition, turned into China’s first diesel locomotive manufacturer rather than a steam locomotive manufacturer. In September 1969 the Company successfully designed and manufactured DF4 mainline diesel locomotive, from then on, DF4 locomotive has become the main type diesel traction locomotive for Chinese railways. During more than 20 years, the Company developed DF4 series locomotive from A to D, in which the DF4B diesel locomotive was designated as a national alternative to imported products and was awarded as the only one national gold brand locomotive in January, 1988. DF4D passenger locomotive became a main type in the first five times of speed increase process in China. On July 2, 2008 China's first high-power AC drive diesel locomotive rolled off from the company and began to mass production. At the beginning of this century, the company implemented a "develop diesel and electric simultaneously" strategy, successfully developed SS4G electric locomotive in December, 2000 and produced in batches. In September, 2002 SS7E electric locomotive was successfully manufactured. In December, 2003 SSJ3 high power AC freight electric locomotive was successfullydeveloped. Since 2004, through the implementation of "Introduction, DigestionAbsorption and Re-innovation" strategy, the Company began to design and produce in volume six axle 7200kW electric locomotives, six axle 9600kW electric locomotives, 6000hp diesel locomotives and developed new world's advanced level HX type high-power AC drive electric and diesel locomotives such as passenger electric locomotive with the speed of 160 km/h, 9600kW eight axle freight electric locomotive, 4400hp diesel shunting locomotives and plateau applied diesel locomotive etc., which become the main types of locomotives for passenger and freight rail transportation.At the same time, the company developed and tested 200kW passenger electric locomotive, 160kW passenger diesel locomotive and 3000hp energy saving environmental protection shunting. Up to February, 2017, the company has designed and manufactured various locomotives and the cumulative productions exceeded 11, 000units, which accounting for 50% of the national railway reserve amout, locomotive products covering all railway bureaus. During the Spring Festivel Rush in 2017, the company produced more than 3500HX3 series high power AC electric locomotives as the main force for railway passenger and freight transportation, “locomotive cradle” made a new contribution to the development of China railway.
