Battery-Electric Locomotive Technology

FLXdrive is Wabtec’s newest development a battery electric freight locomotive.  Leveraging decades of application expertise, coupled with industry leading performance optimization, the hybrid consist that is being demonstrated has the capability of saving fuel and reducing emissions.

Wabtec’s FLXdrive battery electric locomotive pilot is part of a grant project with the Calfornia Air Resource Board (CARB), BNSF and the San Joaquin Valley Air Pollution Control District.  Wabtec and BNSF will begin proof-of-concept and performance testing in late 2020.  BEL is part of California Climate Investments, a statewide program that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions, strengthening the economy and improving public health and the environment— particularly in disadvantaged communities.
