| AHC. Here is a duplicate 35mm color slide of a photo by Bill Price that was taken at the Horseshoe Curve near Altoona, Pennsylvania, on 13 August 1951. The photographer is not identified. Shown here (R to L) are Pennsylvania Railroad engines #5756 and two more units whose numbers are not recorded. All are AP-20's built by the American Locomotive Company and rated at 2,000 horsepower each. #5756 was constructed in November of 1947, later regeared for freight service and reclassified as an AFP-20, and retired in September of 1962 after just 15 years of revenue service. They are pulling a passenger train down the Allegheny Mountains and around the Curve on their way to Altoona, Harrisburg, and points East. The date is an approximation. |
