Here's is a Lionel 2-8-0 Consolidation that I just installed a new smoke unit, Super-Chuffer II, and the Chuff-Generator. This is the first install for the Super-Chuffer II that I've done that actually required the smaller form-factor of the SC-II.
The Super-Chuffer II is actually crammed into the tiny space under the smoke unit, it's the only place that it would fit. If I put it under the Odyssey board, it hung over the edge and looked ugly as you can see that area from the side above the drive wheel. The Chuff-Generator was a similarly tight fit, that's the only place I could mount it, and I had to hog off the cast in mounting post on that side for it to fit. The MTH smoke unit I usually use had no chance of fitting, so I used a LionChief Plus smoke unit.
This is pretty well packed now.
