| AHC. Here is a duplicate 35mm color slide via Al Chione that was taken at the Horseshoe Curve near Altoona, Pennsylvania, c. 1959. The photographer is not identified. Shown here (L to R) are Pennsylvania Railroad engine #9590 and two more "BF" Class units whose road numbers are not recorded. All were built by the Baldwin Locomotive Works. #9590 was constructed in July of 1949, rated at 1,500 horsepower, and retired in June of 1964 after just 15 years of revenue service. In this context, this A-B-A set is pulling a mixed-cargo freight train up the Allegheny Mountains and around the Curve to Gallitzin and points West. |
