For all vehicles and environments

Our traction systems available for all types of rail vehicles, including those not manufactured by Alstom, from trams to locomotives and from regional to very-high-speed trains are specifically designed for all types of traction and operating conditions. Our solutions are guaranteed to meet a wide range of requirements for different voltage levels, extreme temperatures or humidity levels, or when fitting into specific spaces on vehicles for higher passenger capacity.

Eco-designed / Green Traction 

Alstom’s technology solutions are based on eco-design principles: low noise, energy efficiency (including, for example, regenerative braking, natural cooling), high recyclability and low lifecycle costs. As a result of continuous efforts to limit environmental impact, Alstom has developed low carbon alternative traction systems for operation on non-electrified lines, including hydrogen fuel cell-based traction systems and energy storage-based traction systems.
