And you’ve just hit on my Achilles Heel, adding realistic operations. It’s one thing to design a general flow around the room, but quite different adding spurs, buildings, etc., to serve as destinations. In Mark’s case, he had the basic operation in mind for his point to point, so all I did was help connect the 2 points with tracks that would fit. He started with 2 turntables that became reversing loops and eventually were replaced with an around the room design due to changes to the available space. Throughout all the changes, he kept the basic operation intact, city in the lower right up to an industry in the upper right.
In your case, we’re laying down an around the room flow and trying to come up with a reason for it to exist. You’ve got space before the bridge in the lower right for an industry of some sort. You’ve got room past the bridge for a mall towns but the elevation change going up will have an impact. You have room in the elevated upper left for another industry, like timber or mining. Then, of course, there’s the peninsula area where you’d like a turntable. There are others areas for spurs with businesses to be serviced or the passing sidings you currently have. I’m terrible at coming up with a theme because I just like to run trains, not service spurs.
