I remember being a child and building a space station (it looked a bit like StarLab so I guess the station in general was on TV or in a book) with a solar array that shape, my parents were a little angry and asked where that shape came from. I didn’t have a clue so I basically just said I liked the symmetry. They told me that’s a "very bad shape and that I have to rebuild it. It ended up being 8-shaped, which was also nice.

I also have that guy :)

The train on the left is heading into an (under construction) underground section

There are also some leftovers from a crashed monorail train (no monorails were harmed here, it’s built from regular parts).

On the other end the trains are heading into (modified) winter-village.

In between there are some areas that aren’t built yet but there’s quite some space left. Also I’m a little surprised that shelves hold it up that well :D (they are bolted to a substantial brick wall tho).
