In 2018, BNSF and Wabtec (then GE Transportation) joined forces to begin developing a 100% battery-electric, high-horsepower road locomotive prototype that works with conventional diesel-electric locomotives to make a battery-electric “hybrid consist.” Proof-of-concept and performance testing is expected to begin in late 2020.
