I think these roundhouses are some of the most difficult train-related building to create. Very nice job on this Peterab.
I must admit I learnt a lot doing it. In other words my initial plan turned out to have some dumb mistakes and unforseen problems

One of the unforseen problems was another member of my train club has some awesome steam train mocs, based on local prototypes, which are too big for the roundhouse and turntable. Apparantlly the prototype was too big for some of the turntables it used too so they would detach the tender from the loco and turn each part seperately.
I also miss-calculated the angle I needed for the roof so had to rebuild it part way through. Part of my criteria for this building was that each stall would have its own radial slice roof, and they would all be the same size.
I'm about to build a german BR50 which will also be too big. I'm looking at this version as a first prototype at the moment. Now that I've solved some of the problems, I'd like to revisit it to get the size correct, and to improve the asthetics, and break the symetry perhaps by have some long and some short stalls, and adding some loading doors to one side and perhaps a steam driven lathe in a workshop. I think where my entries to the contest lacked was in their livelyness, I need to add minfigs and have them doing something not just standing around.

Let us know when you have more pics available. Very nice roundhouse, I would love to see more details and the turning mechanism as well.
No problem, it may not be quick though, my Lego activities rarely get to be first priority

I'll add an update here when I get the photos up.
I intend to show all the tricky bits to achieve both the angled roundhouse and the turntable mechanism.
