| Yard Power. Here is an original photo that I took of a Pennsylvania Railroad locomotive in Hollidaysburg, Pennsylvania, on 01 September 1960. Shown here is PRR engine #9394, an ES-12 built by EMD in 1950 and rated at 1,200 horsepower. Its crew is switching some cars in the Hollidaysburg Yards, just East of the Juniata River Railroad Bridge. |
