RTR12, Thank you very much for the idea of putting the yard out on a peninsula! It's an excellent solution to the reach problem!! I had originally thought of a peninsula for the mainline, but then thought the curves out and back probably wouldn't fit and keep the wide aisle. We need the 36" for moving things in and out the back door to the stairs and garage door on occasion. I hadn't thought of putting the yard out on a peninsula, but you see folks doing it all the time. I can be pretty dense at times. Maybe that is why they are slowly putting me out to pasture at work! 
BTW, I know from experience that when Dave has been working on a plan, he can whip up some changes in no time flat!!
The peninsula can make it so the mainline out and back tracks can be separated some more for some scenic effect! I know what the prototype was(is) like, and I want to give the feel of it, knowing I can't even come close to replicating any part of it in this space in O gauge. Trouble is, I look at a blank sheet of paper, oh excuse me, computer screen nowadays, and my mind is blank too!
Dave, you are right about the lower right hand corner using the other switches. Also, moving the upper right loops back works nicely. I think the yard lead coming from more of the center like RTR suggested would be good. Yes, I agree, you just threw it out there as a starting point, but I think you had a good feel for where I am coming from as we worked on this last year. You know I'm not a guy who wants a bunch of concentric loops or a serpentine twisted upon itself. I want to get in a bunch of those buildings, mountains, bridges, and the two branches of the Cheat River.
