| 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 are PRR engines #8663 and #8668. Both are AS-18AM's built by the American Locomotive Company in 1958 and rated at 1,600 horsepower each. They have just rounded the Horseshoe Curve, and are returning to East Altoona for yet another run up the Allegheny Mountains to Gallitzin and back. |
