| 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 each. #5789 was built in May of 1952. In this context, they're rounding the Curve with a mail & express train and are heading down the Allegheny Mountains to Altoona and points East. (#17 of 39) |
