| Horseshoe Curve-1966. Here is an original photo that I took at the Horseshoe Curve near Altoona, Pennsylvania, in May of 1966. Shown here (R to L) is Pennsylvania Railroad engine #5789 and two more diesels. All are EP-22's built by GM-EMD and rated at 2,250 horsepower. Among them is engine #5765, built in March of 1952. At Signal Bridge 2416/7, they've rounded the Curve with a mail & express train and are heading down the Allegheny Mountains to Altoona and points East. (#18 of 39) |
