Here's something I knocked up just to give an idea what could be placed in your layout area. It's essentially a double track with a passing loop, a small engine shed twin line with a spare siding, plus a small goods yard and a parcels bay. The scenic break is the orange thick lines and you should be able to have 4 fiddle yard lines per running line. Hope that helps, I've also attached the xtrackcad file if you wish to modify it.
