Congrats on retirement. I very much like your layout. (and very impressed your 3rd garage bay is 30' deep. I was thinking for a workshop? or golf cart?)
Will it affect your plans for minimum radii if sometimes the primary is inside the curve and sometimes outside? I am working on a simple two-track mainline on an upper level in a smaller room, and my minimum (O-72) goes back and forth between the two tracks. Thanks.
