The DDJ1[Note 1] is a first generation high-speed electric multiple unit built for China Railway, built by Zhuzhou Electric Locomotives, Changchun Railway Vehicles, Sifang Railway Vehicles, Tangshan Passenger vehicle factory, Nanjing Puzhen and developed by Zhuzhou Electric Locomotive Research Centre. It was built in 1999, and was an experimental vehicle, with only one set built, as it did not enter mass production. The design was well received as part of national science in the 9th five year plan. The DDJ1 is in a push–pull configuration, with only one locomotive in the set and the other end being a trailer with a driver's cabin.[1]
