I just figured that the battery would have a better shot of providing the power density for a large locomotive to run a few seconds than any supercap we can fit in. I think Stan's picture tells it all.
Yeah, by far the harder parts are the 'gotchas' i posted above.
Supercap, NiMH, Lipo - lots of ways to store energy. We can figure that part out.
