Here are some pics of my layout. Basically a U shape along three walls of the room. There will be an island section in the center later. The room is 17 feet X 17 feet. Still laying track so I'm not as far along as August.
It's all code 83 track so I had to get all new stuff.
This is along the South wall. It's really two switch yards.
24 inches wide by 14 feet. There will be a little section to the left on the east wall. How big it will be will depend on if I ever want to use that bathroom again. The layout will have some trees on it so that may be an option.

The head of the yards. The bridge thing is just a temp. Don't really know what I'll do with it.?????
That leads to the west wall
The NW corner. A double crossover here to get from one oval to the other.
And the North wall. It's 48" X 96" The two dead ends will crossover to the other side via the center island.
GP9 Got another just like it on order DCC with sound.
The little switcher is DCC the others DC.
This one is my favorite. Virgina & Truckee. Ran form the mines in Virgina City to Carson City and than to Reno. Not the right locomotive in this shot.
Some of the rolling stock.
