Horseshoe Curve

Horseshoe Curve is a railroad curve in Logan Township, US, that stretches 2,375 feet (724 meters) and crosses two ravines formed by Kittanning Run and Glenwhite Run. The track follows a wide arc with a diameter of roughly 1,300 feet (396 meters), carrying trains around the steep hillside.

The Pennsylvania Railroad completed this track in 1854, replacing the older Allegheny Portage Railroad as the main connection over the mountains. Military units guarded the curve during World War II because of its importance for moving troops and supplies.

Irish workers spent three years shaping this route through the mountains using methods that were advanced for their time. Their work changed how railroads could be built through difficult terrain.

Visitors reach the observation area by funicular or stairway, both offering direct views of passing trains. The Railroaders Memorial Museum runs an on-site visitor center with information about the engineering and importance of the track.

During the war, German Abwehr agents attempted to sabotage the curve, leading to tighter security measures. Today around 50 trains pass through the curve daily, giving visitors a chance to see modern freight trains in action.
