 twin-section locomotives, but is a single-section locomotive with cabs at both ends. The electronics were updated, with traction converters based on IGBT technology, and an updated version of the MITRAC control electronics developed by Bombardier's Switzerland branch. With increased power and a maximum speed of 120 km/h (75 mph), the locomotives were designed for general freight rather than specialised heavy-haul service. Most of the Artic weather modifications of the Iore, including thick walls, were left away, but the air filters in the ventilation outlets designed against snow and iron ore dust entering the motors were retained to protect against coal dust.

The electronics and traction equipment of the first 150 units were supplied by Bombardier from Europe, production for the rest is shared between Bombardier's Chinese subsidiary and Dalian. The design of the mechanical components was subject to technology transfer from Bombardier to Dalian.
