Surprisingly no one has commented given how opinionated we all are on here;
My view is that a double roundy is twice as good as a single 'cos you can run two trains at the same time, as I developed my theme I ended up with a quad roundy and so it went until I had 8 circuits.
Now you need to rationalise if you like shunting and that sort of activity or watching trains run around. The other difficulty is that the inner area will be where the platforms stations goods facilities are and this comes difficult for the outer line.
I got around this by having loops on the ends so I could keep full trains ready to go.
Headshunts are a poor operating idea
Station loops are good to hold trains, in fact the GCR idea of the London extension of a central platform saves space/width might be worth consideration.
