    So trains in the 6' range with engine(s). That's long for this size layout, but not unworkable. I'd make the main more than once-around, to avoid the tail-chasing impression.

    Do you already have the turnouts? I model in ho, but have noticed that Atlas insists on using stamped sheet metal points in all of their turnouts for ho scale. The spacing between the guard rails and the track is too wide on their ho scale stuff, but that can be solved easily with a little bit of styrene to make some shims to get the distance where the guard rails are actually useful. The bigger problem is that sooner of later the thin sheet metal points will lay over and go out of gauge when weight is put on them as with a train going over them. In my experience with ho, I would go with anything but Atlas for switches.

    Do you want a single or double mainline?

    With 6' trains on this size layout, fitting a visible classification yard will be difficult.

    That's good, because more will probably crowd a layout of this size.

    With a two-lap single-track line, the question is how much separation you want or need between the laps. Larger curves look better, but they force the inner lap closer to the outer, which doesn't look so good.

    Okay, I'll start by assuming generous 1.5" track centers. Then let's say 1.5" is also how close track centerlines are allowed to the edge. Allow room for a siding on the outside of the outer lap, and another on the inside. And the same on the inner lap. With 7" between the closest centerlines, that puts the inner lap main 4.5"+7"+1.5" in, or 13". That means an 11" radius. Hmmm...that was too generous. With more usual 1.25" centers and 6" between closest tracks, you get 13" minimum mainline radius. It should still be bigger...
