China Railways DJ1

The China Railways DJ1 is a high-power mainline electric freight locomotive built as a double locomotive unit of two nominally independent single-cab units. It came out of a technology transfer agreement between Siemens and the Zhuzhou Electric Locomotive Works. The first three locomotives were built by Siemens in Austria and the remaining 17 in China, with the first produced in 2001 and the first Chinese-built unit in 2002, and production ended in 2003. The electrical equipment follows Siemens' second-generation EuroSprinter design with water-cooled GTO inverters and asynchronous AC traction motors, and regenerative braking gives a braking force of about 460 kN. The locomotives hauled coal trains on the Daqin line until the more powerful HXD1 and HXD2 arrived from 2006, after which the 20 units were allocated to Xi'an Railway Bureau to haul freight between Baoji and Qinling.
