I'm going to set up an O48 curve and see about body-mounted Kadees. My problem is this corner wrt the adjacent doorway:
Any curve larger than O48 has the curve ending on the lift-out with the complication that would entail. Still, it might be worth it. I'd just daylight that tunnel I thin k. That O36 track switch will have to be replaced by an O72 version.
