O-31 track is 31 inches to the outside rails, so the ties would overhang your board. The trains will jump off the track at the curves if you run them at speed. O-27 would be a better choice if your engines and cars can handle the sharper curvature. With O-27, you have a cushion between the track and the edge of the table.
I have made sure that everything I pick up is O27 compatible. I agree about the cushion of space being better.
Thanks for responding!
