The Torhaus. Made for 3D printing. If you are wondering why it has a big arched hole in the front, it is for 2 train tracks on a steel bridge structure to pass through the building. If you are interested in how this looks, I have also attached a historical picture of this in the bottom.
UPDATE: THe customer sent me the result of the 3D printing he did. It turned out really well. All that is left is to sandpaper some sections to make everything fit perfectly. Very cool to see your 3D work in real life!
