Thanks! I've still got work to do on it, like the decorative lights around the lower containers I want to extend to the rest of them, and probably change all the floors to coated concrete because it looks nicer. When I come up with good ideas I tend to reuse them in future save files.

For instance here's a couple shots from my previous save where I used many of the same design ideas.

I use trains a lot, and have a whole rail network set up (which I imported from elsewhere, since building out rail infrastructure every new save gets tedious). Putting a train in the middle of my mall lets me use trains as a mobile storage mall. I stock it up with things I need for building, then park it nearby the project I'm working on, so when my personal supplies run low I can restock from the train instead of going all the way back to base. Also I can dump stuff I pick up (slugs, leaves, wood, etc) into the train to free up space in my inventory. And when I want to return to base, I just have to hop in my train, set the autopilot back to base, then sit back while it takes me home. Watching the world go by from the train is its own pleasure.
