Western Feldspar Milling Co in Denver with dual gauge.
I thought this was interesting. Being denver in the 30's with dual gauge track, I assume this might have been the destination of cars coming from the feldspar mines on the Silica branch? Could C&S narrow gauge gondolas have ended up here?
I also am wondering where this mill was. One of the C&S reasons for doing away with the Silica Branch was to "do way" with trans loading feldspar in Denver but that photo shows a 3rd rail. Tom Klinger
