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