Moonman, Thanks for all your efforts, it is appreciated.
So update:
My N layout was fictional Appalachian Coal. I thought I wanted to take this layout to a fictional Ozarks town. Living in flatland, and loving The hillsides, I enjoy modeling that.
However, while N was all about the scenery and overall, I am really feeling the connection with the trains this time, and so, I am driven to model the home town of memphis.
And so my wife pointed out 
Wiki Trolley is another feature of town. I never considered one of these, but its now on the list.
So here it is:
Name - Memphis Junction, ?
Era - today
Proto - NS,BNSF main, guest appearances CN, UP, CSX. I frequently See NS/BNSF lashes. NS/UP lashes, NS/CN lash (more rarely), & CN,BNSF,NS,CSX as 1 roadname lashes. With Railroad terminals in the area for BNSF,CN,CSX,NS,UP, we get to see a variety. Memphis Railfan Youtube (Not Mine)
Trains - 2 Passenger. (1) Hvy weight, (1) Amtrak - I love old heavyweight, and my wife and kids take amtrak twice a year to visit family. The real question is do I pay tribute to Memphis Central, or just have the trains make guest appearances.
Freight - Coal Train, Mixed , eventually an Intermodal.
Trolley Line - requires city scene.
Reason - Still debating. Interchange, or just have mixed lashes staged, and have a small industry at the center. Maybe the passenger terminal as the central feature, except I am not a a diehard passenger guy, but I think it could be fun, so how much space does it game.
This is completely different than what I have done before so I need more research. My N was coal mines in the hills coming down through Mining Company town (shanties), to the Yard.
Considering my space, any kind of decent yard would dominate, and reduce the number of scenic elements. I have two local towns that I could model. Memphis (the city) but also Collierville Square, where train passess through the hisotric district town Square. So I have two good choices.
<EDITE> NOTE : I am not in a rush, as I still have to clear out the space, remove the 220V electric lines from the woodshop, install a new wall at the opening of the garage,remove the garage door, repair the drywall. Then Add one or two interior secondary walls, and that is part of the planning process (don't get into Pedantic Semantics with me on Planning v Design), to determine what space I want to use for the train and the reduced workshop & storage. <EDIT>
