There's one near the station in Wedel, just on the outskirts of Hamburg. Stocks a lot or Marklin and Fleischmann, 30 second walk from Wedel S-bahn station. Wedel is the westernmost point of the S-Bahn, which in itself is very cheap. Its also customary to hand any day tickets to another person once you've used it.

Its human nature to find the facial features in any inanimate object. Look at a car, can you not see a face? Engines seem to respond to that nature very well.

Give Anyrail a try, seems pretty sound when it comes to technical drawing. What you've got seems good, I presume its a loft?
