Gonna get caught up on this thread? Boy... you've gotta a lot of readin' to do!
As for progress: The layout is 100% functional and has been since July of 2019. I've been having a ball operating it off/on over the past year or more with my railroad buddies. Love it.
However, the time is nearing that I need to pull the equipment off the layout for storage, and apply myself to getting the back drop boards, valance, and lighting strips installed.
