My new basement, or, how to fill it

That makes things so much better w/o that wall in the middle. If that' a staging yard in upper left suggest you make it double ended/run through so you don't have to worry about which end your locos are on. Can that room in lower right be removed? It would give you a wider aisle there or maybe another peninsula.
There being a gazillion track plans on the internet, on this forum & many other MR forums, check them for ideas for individual industries & yards for your layout. You can always change them to meet your needs. As a RR civil engineer type told me " Think of lines on paper as a bowl of spaghetti. You can move them around any way you want for your own purposes."
