Jeff, I too like the lashup feature. I have lashed similar diesels and double headed H9 consolidations. Really cool.
Mike, The lights and stairs are a great enhancement on that building.
Jackson, Those are really nice backgrounds making for a nice railroady feel to your industrial area.
Scott, Nosebleed section reminds me of the top of the upper deck at Pittsburgh's Three Rivers Stadium. IT was all the rage when opened, than fans quickly realized it seemed like you were watching the game from a helicopter. So after only 31 years they imploded it. The layout looks good. I had track that close to the edges on my original O gauge 4x8 and never lost an engine, but I don't run trains very fast and don't have any kids around. The copter tour is great. Is the boy in the first photograph your grandson. He looks like he would be responsible. He reminds me of me when I built my first train layout. Congratulations on the planned expansion.
JJWyatt, Excellent advice on making sure you have everything intact right where you unbox trains. I don't have room for a workbench, so I use the edge of the layout or the fold down table of an old sewing machine our older daughter has never picked up since she married and moved out. She buys junkers and repairs them, but this machine has a fatal flaw that is beyond help, so it is my work area and place I do paperwork too.
Back to Mike. After cleaning up a lot of leaves, (still more to do, but it is raining and snow is predicted later this afternoon) I fiddled and fiddled trying to get the wiring to work on my limit switches. I finally did a search for your original build in the Forum search function. I got Stan's drawing quickly by entering the phrase "linear actuator" and mike g. It pulled up links that took me to your topic back in the fall of 2016! I was surprised it was over 4 years ago. So here is Stan's drawing.
I really feel like a fool, but I can't seem to think outside the box. And I was passing myself off as an electronics technician and engineer for 43 years!!! (I guess that was me big accomplishment in life!) 
I couldn't figure out how to tie the power and the normally closed contacts together. Since it is raining I hope to knock this out today. I'll get the soldering iron out as soon as I leave the computer.
