A new heavy-duty electric locomotive rolled off the production line at CRRC Zhuzhou Locomotive Co., Ltd. in Zhuzhou, Hunan on May 9.


CRRC claims this eight-axle electric locomotive to be the world's most powerful permanent magnet direct-drive heavy-duty freight electric locomotive, with a maximum traction power of 10,400 kilowatts. This design allows a single locomotive to carry nearly 1,200 tons more per trip compared to traditional electric locomotives with the same axle count. Annually, this could increase the transportation capacity by nearly 280,000 tons.

Annually, this could increase the transportation capacity by nearly 280,000 tons.

The locomotive incorporates several new technological improvements, including the world’s first high-power silicon carbide converter. This technology enables the locomotive to adapt to a variety of line and grid conditions, ensuring smoother traction.

New electric locomotive also features the world’s first high-torque permanent magnet traction motor. This innovation significantly increases the wheelbase by nearly six times compared to existing motors, allowing it to directly drive the bogie. This change leads to higher transmission efficiency and reduces environmental impact.

New locomotives will be deployed on the Shuohuang Railway, which is the second-largest coal transportation corridor from west to east in China. This deployment aims to support heavy-duty transportation needs and provide a stable energy supply across the region.
