Nickel Plate Road Layout

I'm trying to build this as real as possible using scale "O"rail cars changing the couplers over to Kadees I still have some more to change. I've already built some Custom trucks and trailers that are on the layout. I feel like it doesn't belong in the traditional O scale and O 27 Scale forum because it's not animated and I'm not going that route I'm striving for a realistic look I'm very particular on what buildings I buy and how they look for is realism and scale. The layout will not be a "loopy loop" I'm just running it now like this to test things out and  see how everything works. The layout will be 14 X 12 with a 1960S piggyback ramp off siding when I get it completed
