HXD1 locomotive is designed to improve the domestic railway transportation capacity, and also to promote the modernization of railway equipment technology. It is developed by CRRC Zhongzhou Zhuzhou Electric Locomotive Co., Ltd. combined with the experience of its DJ4 locomotive on China Daqin line. A new type of locomotive for heavy-duty freight on the main line railway. This type of locomotive is suitable for the transportation needs of the long-distance section and the long-slope ramp to haul heavy-duty and long-form marshalling freight trains. The car body adopts the central quantity bearing mode, which is convenient for modular production; the bogie adopts the low traction rod, the basic brake adopts the wheel disc brake, which effectively improves the reliability of the locomotive; the air brake adopts the CCBII brake system and the electric brake It adopts regenerative braking, energy saving and environmental protection; the locomotive has external reconnection control function and is equipped with locotrol remote reconnection control system. The driver can remotely control two heavy on-line vehicles in one driver's cab. The project has been mass-produced to 881 units so far.
