| Horseshoe Curve-1959. Here is an original photo that I took at the Pennsylvania Railroad's Horseshoe Curve near Altoona, Pennsylvania, on 03 September 1959. Shown here is PRR engine #9621, an AF-16 built by the American Locomotive Company in 1951 and rated at 1,600 horsepower. It is the lead unit pulling a westbound mixed-cargo freight train around the Horsehoe Curve and up the Allegheny Mountains to Gallitzin and points West. |
