description Wabtec Locomotive FLXdrive Overview
The Wabtec FLXdrive is a battery-electric freight locomotive developed by Wabtec. Unveiled in 2021, it operates entirely on energy stored in large onboard lithium-ion battery packs rather than diesel fuel. When used in a consist with diesel locomotives, the FLXdrive captures energy from regenerative braking and uses it to assist with propulsion. This system is designed to reduce overall fuel consumption and emissions for heavy freight rail operators.
help Wabtec Locomotive FLXdrive FAQ
How is the Wabtec FLXdrive charged?
The FLXdrive stores electricity in onboard lithium-ion battery packs and can recharge through dedicated charging infrastructure. It also captures energy through regenerative braking while operating in a freight consist.
Does the Wabtec FLXdrive carry a diesel engine?
No. The FLXdrive is a battery-electric locomotive and does not use a diesel engine for propulsion.
How much fuel can FLXdrive save in freight service?
Wabtec's 2021 California pilot reported more than an 11 percent reduction in fuel consumption for the entire train. Wabtec has described later versions with potential savings of up to around 30 percent, depending on the operating profile.
Why is FLXdrive used with other locomotives?
Battery range and charging time make multi-locomotive operation practical for heavy freight. In a consist, FLXdrive supplies electric traction and regenerative braking while diesel units provide additional long-haul energy.
