> And throw them on trains for electric freight without having to run expensive catenaries I'd love to see the math on this, because I can't imagine it will cost less than electrifying railways (at least the heavily used ones) over a prolonged period of time (say, a decade or two). Batteries need to be swapped out which will waste time, and replaced every so often. Catenaries need maintenance and have a high upfront cost, but still..
