Siemens Unveils North America’s First Battery-Electric Passenger Locomotive

Siemens Mobility has introduced the Charger B+AC, the first battery-electric passenger locomotive designed specifically for the North American market, marking a significant advancement in sustainable rail propulsion. Building on the successful Charger platform, which has sold over 400 units, the B+AC replaces diesel engines with a modular battery system and pantograph, allowing it to operate on overhead catenary power or switch to battery mode where catenary infrastructure is absent. The locomotive can reach speeds up to 125 mph under catenary power and operate up to 100 miles on battery alone, supporting multiple charging methods including plug-in, dynamic braking, and catenary charging. Tailored for operators with partial electrification, the B+AC offers flexibility, energy recovery, and compliance with Buy America regulations, being manufactured entirely in the U.S. The Metropolitan Transportation Authority (MTA) and Metro-North Railroad in New York have placed an order for 13 units as part of their railcar fleet expansion for use on partially electrified routes like the New Haven and Hell Gate Lines. Siemens emphasizes the B+AC's role in enabling efficient, sustainable rail investments backed by decades of expertise and a commitment to future-oriented propulsion technology.
