I'd venture to say that the chances of using the old Terminal Station as a station are zero. That place is a working hotel, restaurant, and semi-museum, and its tracks and platforms out back are now parking lots and railcar exhibits.
Perhaps things have changed since my visit, and Bill Haithcoat may know if they have, but as of a few years ago there was still one track at the station that could be accessed by trains. Bill & I, along with another friend, boarded the TVRM's Downtown Arrow at the station for a ride out to their musuem. That train has since been discontinued, but that had more to do with the fact that the train essentially shut down the mainline as it crossed from the station side over to the track leading to the musuem.
