The HXD1D (Chinese: 和谐1D型电力机车) is a semi-high speed electric locomotive developed by CRRC Zhuzhou Electric Locomotive Co., Ltd in association with the Chinese Ministry of Railways Science and Technology Development department (Chinese: 铁道部科技司). The design was revealed in 2012 - it is a 7,200 kW (9,700 hp) power six axle, 126 t (124 long tons; 139 short tons), Co'Co' locomotive with a top speed of 160 km/h (99 mph). It is capable of accelerating a 3,000-passenger, 20-carriage train to 160 km/h within five minutes.

There is a prototype without numbering, with 9,600 kW (12,900 hp) power and 200 km/h (120 mph) max speed. However it was abandoned as the max speed of main lines was downgraded to 160 km/h (99 mph).
