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 approximately , and an electric braking power of , overall efficiency of the machine is more than 85%.
3 of the units were manufactured by Siemens in Austria, the remaining 17 in China; the first locomotive was produced in 2001. The first china manufactured unit was produced in 2002.
Production of the locomotive ended in 2004.
The locomotives were used to haul coal trains on the
Daqin line.
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.
