| TRB. Here is a duplicate 35mm color slide of a photo by David R. Sweetland that was taken at the Rockville Bridge near Marysville, Pennsylvania, on 25 August 1956. Shown here (L to R) are Pennsylvania Railroad engine #9538 and two more "EF" Class units whose road numbers are not recorded. All were built by GM-EMD and rated at 1,500 horsepower each. #9538 was constructed in September of 1948 and retired in July of 1966 after just 18 years of revenue service. In this context, they're just beginning the journey from Enola to Altoona with a mixed-cargo freight train. The Bridge is to the left. ("PrrFan18n") |
