CN has launched a new medium horsepower hybrid electric locomotive developed in collaboration with Knoxville Locomotive Works.
CN will test the hybrid locomotive in various operational conditions across its network as a pilot project to evaluate its potential to enhance operational efficiency and fuel savings. It will mark another step towards more modern and sustainable rail operations.
The 3,200 medium horsepower hybrid unit is built on the traditional CN low horsepower locomotive operating in yards and branch lines. It includes a modern control system, increased horsepower of up to 60%, and a 2.4MWh-700HP battery-diesel engine that is 100% biofuel-ready.
The hybrid system targets a fuel consumption reduction of up to roughly 50% compared to a typical locomotive used in similar operations today. CN expects this initiative will help advance hybrid technology in locomotives and contribute to immediate emissions reductions.
The hybrid locomotive will be deployed in phases over the next six months across several CN yards and branch lines, including Tennessee, Mississippi, and Louisiana locations. Testing will eventually include operations in cold weather conditions in Western Canada.
CN said this phased approach will enable it to evaluate the locomotive’s efficiency and operating protocols. This project is part of CN’s program to achieve the deep decarbonization required to achieve net-zero emissions with the other previously announced locomotive pilots.
