  Growing up there I remember hearing that there was some problem with the tunnels being too narrow and the cars not fitting - but that was probably more local folklore than anything else. Cincinnati is pretty hilly - not San Francisco or Seattle hilly - but enough that I would think developing any sort of system would be pretty expensive and difficult.
