Oh that's right, FRA bans light rail and heavy rail from running on the same lines, right? GJ passenger service would basically have to be DMU/EMU until NSRL is built. But even so, wouldn't GJ still be needed for equipment ferrying, given that NSRL will likely have steep inclines and electric-only compatibility? This seems to suggest than any Grand Junction passenger use would need to be DMU or EMU, not light rail.The only way I could see LRT is if NSRL happens - don't they need to keep this rail available for moving commuter rail trains between the lines? DMU or EMU (hopefully the latter) would allow both rapid transit and train movement.
