The Western Union built and maintained the pole line along the C&S narrow gauge. It was all Morse telegraph, no telephone circuits at all.
Six iron wires. I would dearly love to come up old pole head diagrams that showed what those wire numbers were and which pin positions they
occupied.....
It's been sort of a hobby with me..I've diagrammed a lot of the D&RGW narrow gauge and standard gauge telegraph lines and know what the wire numbers were and where they were located on the crossarms.
The old C&S line has escaped from me so far though.
