I'm currently planning my new layout and here is my current progress (see below). The primary guiding principle of this layout is to have the longest station platform and widest turns possible. Everything else is in service to that. For now, it has 270mm radius turns and the express track is 83cm long. Currently, I have it as a double loop for Local and Express that have separate platforms at the station. There's a couple of industries served by an independent, point-to-point system, leaving the 0-5-0 switcher as the only option for running freight on the outer loops or having some locos do double duty, which is fine. If there were streetcars in Z, I'd have a point-to-point one between the station and the town on the right, but there isn't, so I don't. The shared industrial/passenger yard is prototype for the Jersey City waterfront on which this layout is inspired, but instead of a ferry terminal, I went for lowering the water so I can have a bridge on this otherwise flat layout. Anyway, what do you think? Do you see any problems I might have missed? Keep in mind, while I'm currently designing it using sectional pieces to make things easier, I'm planning on building in flex-track, so the position of everything is fairly approximate.
