I've got so many things I want to include on my future layout but I know I'll never have room for it all so I was thinking about interchangeable scenery modules that would fit on the layout with a spur track leading into the module. Modules I was thinking about would be a small fishing harbor, a spur leading into an oil and coal scene, some storage tanks, loading rack, Oil derrick and a small coal mine with the KCC Plymouth /ore car set bringing coal out of the mine on an elevated track "dumping" into hoppers below, a zoo where the spur would serve a passenger terminal, or a variety of industries. Of course the module size would be limited to make handling and storage manageable. I was thinking of either vertical storage of modules not in use or perhaps under the layout if space is available.
Has anyone else thought of something like this? I seem to remember someone trying to have a removable water feature, pond or lake. I can't remember if it was for a similar reason or was it to be removed to allow access?
