I just got my Ross Switches...I am going to add 2 switching tracks to both longs sides of the layout to put sidings in for some factories on each side. The come off the second loop, if you look closely you can see a switch, I am going to put a yard in on one side and on the other I am going to have a downtown area with the train running through the center of town.
You have to decide exactly how you want to run your trains. Do you want to actually work them or will you be content to just run them. I am trying to set this layout up so you do not have to touch anything by hand. I am going to cut in uncoupling buttons etc so I can make the consists prototyically. Any more questions you can email me. Thanks for looking.
