Charles, one thing to consider is where you want to put your bridges. The design before I added the Wye assumed the 30" MTH bridge would be the lift out/up. Unfortunately, you can't put a switch or curve on such a bridge. Even more unfortunate, I don't see where you can put bridges in either design other than the entry point because both designs have so many tracks close together. Obviously, you could add more bridges, but you'd have to consider how that will look and how to landscape it that makes sense.
Then I noticed the lift "up" idea had a potential problem. A lift-up usually needs either the rails at the joint cut at an angle or a hinge where the hinge point is at the top of the rail. You'd have look through the Mark Boyce thread, and others, to see what hinge mechanism he/they used. Obviously, the lift "out" is the easiest to build and there are ways to avoid having to unplug wires.
In any case, I modified the design a bit so the switch is not at the edge of the lift out/up. I also changed a few things to make some areas smoother. I need to recolor-code the small fitters and then I'll post updated photos and parts list.
One other note is that if you reconfigure the interior of the inner loop, it could include a turntable with whiskers instead of the dual spurs with crossovers. You could also keep the Wye if you wanted. I'll also work on that.
