Locomotives, Propulsion & Controls

CNR Dalian Locomotives and Rolling Stock Co. Ltd. and Bombardier Transportation, Division Locomotives and Equipment, signed a contract in February 2007 for the production of 500 heavy-haul Co’Co’ locomotives with state-of-the-art, high-efficiency technology.

The first and highest power member of the Harmony (HX) series electric locomotive, named HXD3B0001, was rolled out from the workshop in Dalian city on 29.12.2008. This is a world record for development, a great result for both com- panies. Never before was such a high power locomotive (9 600 kW) built in a single carbody unit.

The design concept relies on Bombardier’s successful IORE locomotives delivered to LKAB, Kiruna and presently running in Northern Sweden and Norway. The mechanical design was, however, adapted to the single section with dual cab arrangement and for the increased 120 km/h speed.

Bombardier Locomotive’s scope of the new world class locomotive is the vehicle design concept and the highly sophisticated control and communication software and diagnostics. In addition, Bombardier provides professional coaching for employees of the partner company, focusing on detailed design and adaptation engineering, as well as manufacturing and assembly works, including testing and product introduction.

Bombardier’s Business Unit Propulsion and Controls deli- vers major equipment to the new heavy-haul locomotives: the most modern IGBT-controlled traction converter with integrated auxiliary inverters and traction motor with nose- suspended drive unit and the TCMS control system. These noble parts are based on the BOMBARDIER* MITRAC* technology, tried and proven in the largest modern electric and diesel-electric locomotive platform: BOMBARDIER* TRAXX* locomotives.
