| Horseshoe Curve-1966. Here is an original photo that I took at the Pennsylvania Railroad's Horseshoe Curve near Altoona, Pennsylvania, during early May of 1966. Shown here is PRR engine #8668, an AS-18AM built by the American Locomotive Company in 1958 and rated at 1,600 horsepower. It is rounding the Horseshoe Curve at the head of a westbound ore train, but will uncouple at Gallitzin and return to East Altoona for yet another run up the Allegheny Mountains to Gallitzin and back. |
