Walther's GoldenFlame Fuel -- what size town would it serve?

[OldEastRR]

What with the siloes and other stuff, I'm thinking this company would have a pretty good-sized customer base, assuming most of the coal was used for residential (time frame is early 50's). Therefore I see it as set in a rather large city setting.  For a large town or smallish city, I'd expect a modest arrangement of a coal trestle and some outbuildings. Any opinions or examples?

Our little town of 1000 had a dealer with three sizable silos. They stayed long after the business shut down.

We had one similar in my home town of 3000. It hung around until the mid 70`s..

There are the remains of a three-silo outfit in DC.  There's also the remains of an outfit with 6+ silos in DC.  It's not necessarily the size of a business is in direct correlation to the size of the town, as it's not like a bigger town would have only one large dealer serving all town customers versus numerous small dealers serving the same market.  Conversely, a business in a smaller town could serve a region much greater than the town itself.  What determines the size of an industry is more the market-share the business had, or aimed for.
