In a beautiful fall autumn environment as are the Allegheny Mountains, NS freight go down to Altoona by the famous Horseshoe Curve, NS Pittsburgh Line, in Altoona PA. Erie Lackawanna SD45-2 No.1700 accompany the NS locomotives SD70 No.2319 and SD60I No.6726. 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!.
