The HXD3B () represents a series of electric locomotives engineered specifically for heavy freight operations. This class was developed through a collaboration between Bombardier Transportation and CNR Dalian Locomotives.
History
In February 2007, the Ministry of Railways of the People's Republic of China (MOR) placed an order for 500 units valued at €1.1 billion (equivalent to US$1.4 billion), contracted to Dalian Locomotives and Bombardier Transportation. Bombardier's portion of the contract amounted to €370 million (approximately US$480 million). The inaugural locomotive, HXD3B0001, was handed over on 29 December 2008 in Dalian, with plans to complete the entire delivery by the close of 2011.
Technical details
The HXD3B design is based on Bombardier's MTAB Iore twin-section locomotives but modified into a single-unit format featuring driver cabs at both ends. It integrates advanced electronics, including traction converters utilizing IGCT technology alongside an upgraded iteration of Bombardier's MITRAC control system. Built for versatile freight service with enhanced power output and a maximum speed of , the HXD3B aims to serve a wide range of freight applications rather than focusing solely on heavy-haul tasks.
For the initial batch of 150 locomotives, Bombardier supplied the electronic and traction systems from Europe; subsequent manufacturing responsibilities are divided between Bombardier's Chinese subsidiary and Dalian. The mechanical design process included technology transfer from Bombardier to Dalian, facilitating domestic production capabilities.
