In a beautiful fall autumn environment as are the Allegheny Mountains, EMD GP9 No. 7048 building in 1955, owner Pennsylvania Railroad, on display at Horseshoe Curve, NS Pittsburgh Line, in Altoona PA. Photo taken with permission of the Altoona Railroaders Memorial Museum, who authorized me to enter despite being closed. I got confused with the dates, but fortunately I did not miss the trip, many thanks!.
