| AHC. Here is a duplicate 35mm color slide that was taken at the Horseshoe Curve near Altoona, Pennsylvania, c. 1964. Shown here (R to L) is Pennsylvania Railroad engine #9551 and a pair of B-units whose road numbers are not recorded. All were built by GM-EMD and rated at 1,500 horsepower each. #9551 is an EH-15 built in December of 1948, rebuilt later as an EF-15A, and retired in September of 1965 after just 17 years of revenue service. The photographer's name and the exact date are not recorded. Produced and distributed by the Hawk Mountain Chapter of the NRHS. |
