Joe,
By your reply to my suggestions, I'm not sure I made myself clear. I was suggesting that you place the initial switch for your yard in the northwest corner and run your yard lead all the way down the west side. At the southwest corner, the lead would curve into a mirror image of the yard you now show. If you shrink your ovals enough on an east-west basis, you could easily include a yard lead and an A-D track on the west side without jeopardizing your reach issue very much.
