I finally came up with a layout I think I can be happy with on the 4x8. Gonna order all new track with some of the tax money and I think this will become permanent. At least until I figure out how to add a room or two on the house. 
(Yes I know it's on a 5x9 but this was done with Atlas O which is 10" track. It will fit when I go down to Lionel O27 track)
