| Horseshoe Curve-1966. Here is an original photo that I took at the Pennsylvania Railroad's Horseshoe Curve near Altoona, Pennsylvania, during mid-May of 1966. Shown here is PRR engine #6022 and two other units whose numbers are not visible. #6022 is an EF-25A built by EMD in 1965 and rated at 2,500 HP. They are returning to East Altoona for another run up the Allegheny Mountains to Gallitzin and back. |
