These photos show my 12'-by-8' layout completed in 2004 on Mianne benchwork. Perhaps they will give you some ideas - although I think my layout differs from what you're planning. There are three independent loops (Atlas O-72, O-54, O-36). The two outer loops each have two switches into a passing siding. The middle loop also has a switch leading to a stub track beneath the coal tower. I can run three trains at a time, have two others parked on the sidings and another under the coal tower. Conventional operation with power controlled by SPST switches. Beneath the bridges is a non-operational four-track yard used for parking cars and locomotives.
At the time I built this, Atlas O-63 was not on the market. Today I would use O-72, O-63, O-54.
