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).
