| 12th Street. Here is an original photo that I took of a Pennsylvania Railroad locomotive in Altoona, Pennsylvania, during January of 1966. Shown here is PRR engine #8606, an APS-24MS built by the American Locomotive Company in 1955 and rated at 2,400 horsepower. It is about to pass under the 12th Street Bridge on its way back to East Altoona, after making a helper/pusher run up the Allegheny Mountains via the Horseshoe Curve to Gallitzin and back. |
