I know you got your answers, but I just moved to the Syracuse, NY area and I don't know anyone here with a 2 rail layout. I went to the one hobbyshop and he looked at me funny when I said I did O scale 2 rail. When I lived in Savannah, GA I knew one other person that had O scale 2 rail, but he had an HO layout not O scale.
I am planning to start a small 2 rail (switching) layout in January or February of 2023. I think I have room for 3-4' x 16'...small but manageable. Rather have something than keep my trains in the boxes.
