| Here is a photo by H.W. Pontin via Rail Photo Service that was taken at the Horseshoe Curve near Altoona, Pennsylvania, in July of 1940. Shown here is Pennsylvania Railroad engine #4317, an I-1SA built by the Baldwin Locomotive Works as an I-1S during December of 1922, rebuilt in Juniata as an I-1SA in February of 1942, and retired in June of 1953 after 31 years of faithful service. In this context, it's rounding the Curve with a mixed-cargo freight train on its way up the Allegheny Mountains to Gallitzin and points West. John S. Fisher Collection; #5 of 14. |
