Heavy Haul
High Power Electric Locomotives
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 companies. 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 delivers major equipment to the new heavy-haul locomotives:
the most modern IGBT-controlled traction converter with
integrated auxiliary inverters and traction motor with nosesuspended 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.
