100 years ago, nearly every town served by a railroad had one of these, for local delivery of coal to homes and businesses. There is one in the town next to where I grew up, still in reasonable condition. There are many styles of these, from wood to concrete, but they all had several sections for the different sizes of coal. These pictures are of an O scale model similar to the one I remember.
So, time to build! First I glued up some PVC to an approximate thickness of the walls. Cut them to length, and put some aluminum channel on top to get a feel for proportions. Not too bad.
