This is a picture of 3 double track engine sheds. It is level 2 you see now that I have screwed the boards down so now you cannot see the 13 trains below.

At the far end on your right you see the 009 track being prepared for level 4 scene for trams on N gauge track.  Trams are narrow gauge with 00 gauge bodies but the model I have has N gauge wheels to fit the tracks.  I built these a few years ago.  

This is a close look at level 4 tram line under construction.

This shows you a bit more of the tram line behind the church.

This is a picture of where the 00 trains will go under the bridge and trams above at level 4. The holes are to be covered with lift-of scenery to fix derailed trains.
