The pic is in Morenci. The big building behind it is the Detroit Copper Company Store. The car in the middle is MS parlor/coach 102. The open car is like one of the cars built by the Coronado RR. The dual gauge track on the foreground is interesting as is the car on the left with odd lettering. I was not aware of any standard gauge in Morenci until the Shannon Arizona line from Clifton was rebuilt in the 1930's and became the Phelps Dodge Industrial RR. It looks like the dual gauge is standard/3 foot. I would expect to see any dual gauge in Clifton to be 3 foot/20".
