Horseshoe Curve (Pennsylvania) [SEP] Introduction
Horseshoe Curve is a three-track railroad curve on Norfolk Southern Railway's Pittsburgh Line in Blair County, Pennsylvania. The curve itself is about long and in diameter; it was completed in 1854 by the Pennsylvania Railroad as a way to lessen the grade to the summit of the Allegheny Mountains. It eventually replaced the time-consuming Allegheny Portage Railroad, the only other route across the mountains for large vehicles. The rail line has been important since its opening, and during World War II the Curve was targeted by Nazi Germany in 1942 as part of Operation Pastorius. The Curve was later owned and used by Pennsylvania Railroad successors Penn Central, Conrail, and Norfolk Southern.
