Done with 24" radius curves and flex track. Other than some snap switches I already have to use for sidings, everything will be #6 turnouts and 24" or greater radius.
The main line that would run around the room could be completed at a later date. Extending the curves as far as the 18" benchwork allows enough room for trains to pull past the turnouts, line them, and proceed.
Still too hot for drywall work, new windows are being installed down there this week though.
