Just Suppose...

[Sumpter250]

Just suppose that your "industry along the rails" is a tourist railroad associated within a particular area and includes a theme park, such as a tourist railroad in an old logging area that includes a park, museum, facilities, etc. What does your "industry" look like then?
What if your "industry were the Railroad Museum in Golden, Colorado?
Wouldn't the entire "industry" be more or less self-contained, and an entire layout at the same time?

Yes, in fact, my Railroad, is a "working Museum", that subcontracts Less-Than-carload-loads, from the Northeastern roads, and transports them in Steam Era rolling stock, pulled by restored steam loco's, in exchange for track-age rights.
"tourist" comes in, in the fact that the "Cindys Harbor" has Photo platforms built at several spectacular scenic locations ( mostly located on interconnecting short runs of right-of way between the larger railroads ),that, for a small fee, let rail fans get some pretty neat photos of "Steam Freight".
Golden, Colorado ?....no, more like "Out East" ( Eastern Long Island), and "Down East" ( Maine, and New England area )
"Looks like" ? .......Looks a lot like a successful, wholly owned subsidiary, of a thriving Eastern Ship building and Dry Dock Company.
