ev_state Completed in 1854 by the Pennsylvania Railroad to lessen the hard grade up to the summit of the Allegheny Mountains, the curve is over 2000 feet long and over a 1000 feet in diameter. The trackage was later owned and used by Pennsylvania Railroad successors Penn Central, Conrail, and now Norfolk Southern. Horseshoe Curve is listed on the National Register of Historic Places, designated a National Historic Landmark, and was named a National Historic Civil Engineering Landmark in 2004. The location has long been a tourist attraction, with a trackside observation park established as early as 1880. In the 1990s the park was renovated and a new visitor center constructed. Today the Railroaders Memorial Museum in Altoona manages the center, which daily sees the passing of numerous Norfolk Southern freight movements and Amtrak's daily Pennsylvanian regional passenger train.

    The Horseshoe Curve opened February 15, 1854 and was engineered by J. Edgar Thompson. It is located at Kittaning Point, at the base of the Allegheny Mountains.

    The length of the curve is 2375 feet. Degree of curvature is 9 degrees; 25 minutes; central angle is 220 degrees. Elevation of lower (east) end of the curve is 1594 feet, upper (west) end is 1716 feet-122 feet total elevation climb. The grade is 1.8% or 1.8 foot rise per 100 feet.

    The construction of the Curve was done by about 450 workers, many of them from Ireland. The work was done entirely by hand, and workers were paid 25 cents per hour for a twelve hour day.
