In 2011, CRRC Zhongzhu Zhuji notified the bidding procurement to bid for 95 electric locomotive orders. In 2013, it also won an order for 459 electric locomotives, creating the largest order for the export of high-end rail transportation equipment to date. The car is a single-end cab. The locomotive has a track gauge of 1065mm and can operate under AC25KV/DC3KV two current systems with a maximum speed of 100km/h. The locomotive body is an overall load-bearing structure with a compression load of 4.45 MN and a tensile load of 4 MN. It adopts self-developed electric traction system, microcomputer network control system, narrow-gauge bogie, wireless data transmission system, intelligent energy management system and so on. The vehicle is equipped with an AAR-compliant air brake system and a WDP system (hard-wire power dispersion control system). South Africa's dual-flow narrow-gauge electric locomotive is China's first dual-flow AC drive export electric locomotive with independent intellectual property rights. It has filled many domestic technical gaps and also created a multi-flow electric locomotive development platform in China.
