Richie,
Well, the storm only dropped a couple of inches here in Jersey across from Philly. Good luck to you! Same to you John (TR18)
I took your photo and made a translucent rectangle for the room. A couple of questions and thoughts...
Is the family room used by children? If yes, and perhaps it doesn't matter, I am thinking that the mainline should run out there and back and be empty of trains when not in use. Move your yard inside.
No children, I would leave the yard in the family room like a display.
It looks like you are avoiding an object in the top right corner. True?
Are you trying to use existing inventory and purchase a minimum of new track?
