No idea what a locomotive frame looks like, but I’m sure the form factor will work without the diesel fuel tanks. What I really like, though, is the idea of melding an elegant energy solution (heat first, and electric as it evolves) into an aluminum or copper processing plant with minimal use of transformers.
