It was in production from 1984 until the middle of the 1990s, with batch production starting in 1989. The revised DF8B is still in production today. DF8 are almost exclusively used for freight services. ModelsDF8The first generation DF8 was powered by the original {{convert|3310|kW|abbr=on}} 16V280ZJ engine. DF8BThe second generation DF8, the DF8B, is powered by an updated 16V280ZJA engine with {{convert|3680|kW|abbr=on}}. Production started in 1997 and lasts until today. Qishuyan, Dalian and Ziyang manufacture 0, 3000, 5000, 7000 and 9000 series of DF8B respectively. Venezuela version12 DF8Bs were exported to Venezuela and are called DF8Bven, however they are identical to the domestically used DF8B.[1] 7000 Series versionIn 2000, Qishuyan Locomotive and Rolling Stock Works made two radial bogies and equipment in a DF8B Diesel Locomotive. The locomotive and was numbered DF8B-7001. But because it was experimental, only one locomotive was produced. It belongs to Liuzhou Locomotive Depot, Nanning Railway Bureau now.[2] 9000 Series versionQishuyan Locomotive and Rolling Stock Works made DF8B 9000 Series version which was originally intended to be used on the Qingzang Railway and numbered DF8B-9001 and DF8B-9002.[3] Jamaica versionCRRC Qishuyan will supply a variant of the DF8B to Alpart for use in Jamaica.[4] DF8BJThe DF8BJ, which uses the 16V280ZJG engine ({{convert|4,000|kW|abbr=on|disp=or}}), GTO VVVF inverter and AC traction motors, is produced by Ziyang.[5] It was designed for Qingzang Railway. DF8CJThe DF8CJ version is produced by Qishuyan Locomotive and Rolling Stock Works and has a 16V280ZJB engine (maximum power {{convert|4.4|MW|abbr=on|disp=or}}) and AC inverter traction drive.[6] DF8DJZiyang made a special DF8B which was originally intended to be used on the Qingzang line and was numbered DF8DJ-0001. The DF8DJ version has a Caterpillar 3516 engine of rated power {{convert|5.08|MW|abbr=on}} and AC asynchronous traction motors.[7] Rated power of this locomotive is {{convert|4.8|MW|abbr=on}}. The Chinese Ministry of Railways rejected the proposal and it was renamed DF8B-5672. It's now running on Xiyan Line in Shaanxi. ManufacturersThe original DF8 was manufactured by Qishuyan Locomotive and Rolling Stock Works, the DF8B is also manufactured in Qishuyan by Qishuyan Locomotive and Rolling Stock Works and in Ziyang by CSR Ziyang Locomotive Works.
