| Horseshoe Curve-1966. Here is an original photo that I took at the Pennsylvania Railroad's Horseshoe Curve near Altoona, Pennsylvania, during mid-May of 1966. Shown here is PRR engine #7144 and another unit whose number is not visible. Both locomotives were built by EMD. #7144 is an EFS-17M built in 1957 and rated at 1,750 horsepower. They are pulling a westbound mixed-cargo freight as the Sun has begun to sink toward the horizon. |
