| Horseshoe Curve-1961. Here is an original photo that I took at the Horseshoe Curve near Altoona, Pennsylvania, on 17 August 1961. Shown here (L to R) are Pennsylvania Railroad engines #9631 and #9630. Both are AF-16's built by the American Locomotive Company in December of 1951 and rated at 1,600 horsepower each. In this context, they're pulling a mixed-cargo freight train around the Curve and up the Allegheny Mountains to Gallitzin and points West. |
