CN expands hybrid locomotive program

CN is expanding its hybrid locomotive development program following the successful test of its first hybrid locomotive, which launched in January 2025.

CN now has three locomotives undergoing testing and is working to convert two others into hybrid-electric platforms with AC traction technology by the end of 2026.

Through this industry-first approach, CN expects to improve fuel efficiency, reliability and operational performance while extending asset life and reducing emissions, CN officials said in a press release.

“By repowering and enhancing existing yard locomotives, we are being more efficient while supporting service to our customers and more sustainable operations for the long term,” said Patrick Whitehead, CN’s executive VP and chief operating officer.

The pilot locomotive achieved up to a 50% improvement in fuel efficiency, along with significant reductions in traditional engine-related failures, increased horsepower, and reduced idling contributing to lower noise and emissions, CN officials said. Testing was conducted in both hot and extreme cold conditions.

This initiative reflects strong cross-functional collaboration between CN’s mechanical, transportation, procurement and sustainability teams as CN continues to enhance the next generation of yard power for its North American network, officials said.
