Union Pacific Tests Battery-Electric Locomotives in Southern California Corridor

Union Pacific has begun operational testing of battery-electric locomotives in Southern California, one of North America's busiest rail corridors. The railroad is evaluating battery-electric powertrain technology as carriers transition from diesel propulsion. Emissions regulations and operational efficiency gains are driving adoption. In parallel, powertrain conversion specialists like Janus Electric are expanding operations in California and Texas, retrofitting existing diesel tractors with swappable battery systems. Both rail and trucking operators are pursuing battery-electric propulsion through different approaches: new-build electrified equipment and retrofit conversions. Union Pacific's Southern California testing could accelerate deployment decisions across its broader network.
