Back n the 90's, Model Railroader had a track plan for what I believe was a 9x11 foot shelf switching layout with a transload area/yard on one leg and a heavy industry (I believe that it was for modular homes) on the other leg.
It had hidden staging behind both legs of the layout.
The article's author envisioned a CF7 doing the switching.
