China Railways DJ1
Encyclopedia
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.
, and the remaining 17 were built in China.
The electrical components in the locomotive are based upon Siemens' EuroSprinter
design (second generation using water-cooled GTO
inverters). The traction motors are asynchronous AC type, and are nose suspended on the axle, regenerative electric braking is possible with a braking force of ~460kN, and a electric braking power of 6.4MW, overall efficiency of the machine is more than 85%.
The locomotives were used to haul coal trains on the Daqin line
.
Production of the locomotive ended in 2004.
As more powerful locomotive models HXD1
and HXD2
entered Daqin line since 2006, the 20 DJ1s were allocated to Xi'an Railway Bureau to haul freight trains running between Baoji and Qinling.
Background and description
The locomotives are based on a technology transfer agreement between Siemens and Zhuzou Electric locomotive works (ZELW). The first three locomotives were built by Siemens in AustriaAustria

Daqin Railway
Daqin Railway , also known as the Daqin Line , is a 653 km coal-transport railway in north China. Its name is derived from its two terminal cities, Datong, a coal mining center in Shanxi province, and Qinhuangdao, of Hebei province, on the Bohai Sea.The railway also passes through the...
