| AHC. Here is a duplicate 35mm color slide by an unidentified photographer that was taken at the Horseshoe Curve near Altoona, Pennsylvania, c. 1961. Shown here (L to R) is Pennsylvania Railroad engine #9474 and two more units whose road numbers are not recorded. All were built by Fairbanks-Morse and rated at 2,000 horsepower each. #9474 was constructed as an FP-20 in June of 1948, later regeared and reclassified as an FF-20, and retired in November of 1962 after just 14 years of revenue service. In this context, this A-B-A set is rounding the Curve with a freight train on its way up the Allegheny Mountains to Gallitzin and points West. |
