| Yard Power. Here is an original photo that I took of a Pennsylvania Railroad yard locomotive at Hollidaysburg, Pennsylvania, during July of 1960. Shown here is PRR engine #7922, an ES-12 built by EMD in 1957 and rated at 1,200 horsepower. It is "flat humping" a string of freight cars in the Yard. This photo was taken near the Yard Master's Office, at the very eastern end of South Juniata Street. |
