Batteries NOT included but highly encouraged
BNSF and GE Transportation (now Wabtec) began development of the battery-electric locomotive in 2018, supported by a grant from the California Air Resources Board as part of its Zero & Near Zero-Emission Freight Facilities programme. The BNSF prototype is fitted with a lithium-ion energy storage unit with around 20 000 cells containing a combination of nickel, manganese and cobalt.
