A bout a hundred years or so didn't trolly cars run on electrified wires strung above their routes? To me that would seem to be a somewhat logical impractical way to power the trains. Maybe install solar panels and windmills on the locomotives. That way the faster they go the more electricity the windmill will generate. Or could the whole idea of eliminating diesel locomotives is just too stupid for any solution. Jim.
No no, the windmill blade will pull them along like an airplane, the faster they go the more efficient they become until they reach perpetual motion and or warp speed.
