It has been in production since 1976 and is still produced as of 2006 by several local companies. It is the most common road switcher in China and is used for yard and road switching duties. A small number are also in service with the Korean State Railway in North Korea.

In January 1976, the first DF5, DF5 0001, was rolled out at Tangshan. The DF5 has many features in common with the DF4, such as the bogies, the electrical system and other major components. DF5 0001 subsequently underwent testing at Fengtai West Station yard, which provided data for further enhancements to improve the performance and reliability of the locomotive.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4On 26 July 1976, the day before the Tangshan earthquake, the second unit, DF5 0002, was completed.[1] The factory was severely damaged in the quake, and over 1,700 employees were killed; despite this, less than two months later, in September 1976 the second unit left the factory, and production work resumed. Between the end of 1976 and 1979, a temporary facility was erected at the Tangshan plant, where 25 DF5s were then produced. This early batch of DF5s has since been nicknamed “Earthquake.” By 1981, the Tangshan plant had produced 32 locomotives of the type.The units produced after the earthquake suffered from relatively poor quality of the main components, the poor matching of the turbocharger with the diesel engine, poor performance and other problems. To further improve the DF5, the Ministry of Railways halted the production of DF5s at Tangshan, the Dalian Locomotive Works began work on redesigning the locomotive and the 8240Z diesel engine.In 1983, the Dalian works redesigned the 8-cylinder inline 8240Z, turning it into a V8 with equal performance, designated 8240ZJ; in 1984, the first Dalian-built unit, DF5 1001, left the factory and was assigned to the Jinan locomotive depot for service testing. The redesigned locomotive not only eliminated the excessive vibration and other shortcomings, but improved significantly upon the initial and continuous tractive effort.[2]By an order of the Industrial Development Bureau of the Ministry of Railways, the improved DF5 was ordered into full serial production at the Qingdao Sifang Locomotive Works.[3]From 1994, new DF5s were built with the improved 8240ZJC engine, producing 1,320 kilowatts (1,770\u00a0hp); a total of 251 were built (numbers 1701 to 1951). In 1989, Sifang produced 26 units for operation along the Sino-Soviet border. Of these, eleven (numbers 4001 to 4011) were built for operation on Russian-gauge track (1,524 millimetres (5\u00a0ft 0\u00a0in)), the remaining 25 (numbers 5001-5015) were for standard-gauge use. These are assigned to the locomotive depots at \u00dcr\u00fcmqi, Jining and Mudanjiang.[3]In 2001, Sifang developed a much improved version of the DF5 that addressed many of the problems associated with the previous types. By 2006, 132 locomotives of the new design had been built (numbers 1952 to 2083).As of 2006, Tangshan, Dalian and Sifang have produced over 1,100 locomotives of class DF5 between them.Running numbersQuantityBuilderBuild yearsRemarksPhoto0001-003232Tangshan1976-1981  10011Dalian19841002-1700699Sifang1984-1994  1701-1951251Sifang1994-20018240ZJC diesel engine  1952-2083132Sifang2001-2006Improved DF5  4001-401111Sifang1989-1991Broad-gauge border type5001-501515Sifang1989-1991Standard-gauge border type6001-60055Dalian1991For Liaoning Jinxi Natural Gas Chemical PlantPreserved units[edit]North Korea[edit]  \ub0b4\uc5f0101 at P’y\u014fngyang Central Station.At least eight units have been delivered second-hand to the Korean State Railway, where they work on local passenger and freight as well as shunting duties around North Korea, including at P’y\u014fngyang and Namyang.[4] They are numbered \ub0b4\uc5f0101 to \ub0b4\uc5f0108 (\ub0b4\uc5f0 = Naey\u014fn, “internal combustion”) and retain the blue and white China Railway livery.References[edit]External links[edit]     (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4"},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/china-railway-df5-wikipedia\/#breadcrumbitem","name":"China Railway DF5 – Wikipedia"}}]}]
