Siemens Mobility has announced the launch of the Charger B+AC, the first battery-electric passenger locomotive developed specifically for the North American market. The new model represents a significant step in advancing alternative propulsion technologies across the region.
Manufactured in the United States, the Charger B+AC builds on Siemens Mobility’s established Charger platform, with more than 400 units already sold in North America. This next-generation model removes the traditional diesel engine, replacing it with a modular battery system and pantograph, enabling operation under overhead catenary wires and in battery mode where catenary infrastructure is unavailable.
The locomotive is capable of running at speeds of up to 125 mph under catenary power and can travel up to 100 miles on battery alone, depending on route conditions and train configuration. Designed with flexibility in mind, the B+AC can be charged via overhead lines, plug-in connections, or through dynamic braking.
“Expanding our portfolio with the Charger B+AC emphasizes our dedication to providing the best propulsion solutions for every customer need,” said Andre Rodenbeck, CEO Rolling Stock at Siemens Mobility. “With a growing range of battery, hydrogen, and hybrid propulsion technologies, we’re empowering operators to make efficient, sustainable, and future-oriented investments – supported by reliable platforms and decades of rail expertise.”
The introduction of the Charger B+AC complements Siemens Mobility’s broader range of sustainable propulsion technologies, which include the battery-electric Mireo Plus B, the hydrogen-powered Mireo Plus H, and hybrid-capable Vectron locomotives. The new locomotive is designed to support transit agencies with partial electrification across their networks, offering seamless transition between power modes without compromising performance.
MTA ordered 13 Charger B+AC locomotives
The Metropolitan Transportation Authority (MTA) and Metro-North Railroad in New York have already placed an order for 13 battery-electric locomotives as part of their latest railcar fleet expansion. This marks a key milestone for Siemens Mobility, demonstrating growing interest in battery-powered rail solutions across the United States.
In addition to environmental benefits, the Charger B+AC features a familiar operator interface and a common parts pool shared with existing Siemens locomotives in North America. This ensures easier maintenance and cost-effective scalability. The modular battery system also allows future upgrades and supports operational adaptability, including adjusting train length to match varying passenger demand using existing rolling stock.
Siemens Mobility says the new locomotive offers operators a practical solution to decarbonise passenger rail while maintaining high service levels. Fully compliant with Buy America requirements, the Charger B+AC supports the country’s broader goals for clean transportation and infrastructure investment.
With this latest development, Siemens Mobility aims to reinforce its position as a leader in sustainable rail technologies and help shape the future of low-emission rail transport in North America.
