I have been watching and reading this for the past few days, and seen this evolve. I like a lot of it. Well done. A question I would ask is what kind of operating do you want to do? You have a lot of switches, are you looking to do a lot of switching operations or are you going to be a looper, watching your trains run around the tracks. My view is that if you are going to be a looper then all those extra switches just equal extra expense, and extra time for not a lot of real estate. Said another way - how many cars do you think you can store on those sidings? My guess is fewer than you think, and I ran into this same issue. I have two yards on my layout, and mostly they are used for on track storage as I am a looper.
