After browsing the web and seeing Paul Templar's On30 layout, I was amazed! So I dreamed up this On30 layout in 8'x6'x18". I don't know if the track clearance is correct, after all I'm a N-scaler :teeth: . Grid=4"
Those appear to be 4" squares, in which case you have 2" track centers. Those are fine on straight track in HO, but On30 trains are considerably bigger. Also, those look like #3 turnouts - too tight. The curve in the lower part of the wye is about 8" radius.
