The city established the Horseshoe Curve Task Force to investigate the feasibility and costs of restoring No. 1361. In 1985, the Railroaders Memorial Museum was granted possession of the PRR 1361 on condition that a suitable replacement be provided to the Horseshoe Curve; Conrail subsequently donated PRR 7048, a GP9 diesel-electric locomotive ...
A stereo card of a train on the Horseshoe Curve, c. 1907. Horseshoe Curve, a curved section of track built by the Pennsylvania Railroad, located at MP 242 on the NS Pittsburgh line, has become a tourist attraction and National Historic Landmark. The curve was built to help trains cross the Allegheny Ridge, a barrier to westward trade.
A horseshoe curve is a means to lengthen an ascending or descending grade and thereby reduce the maximum gradient. Grade or gradient is defined as the rise divided by the run (length) or distance, so in principle such curves add to length for the same altitude gain, just as would a climbing spiral around one or more peaks, or a climbing traverse (cutting) wrapping around an end of a ridge.
[5] [18] No. 1361's former display location at the Horseshoe Curve was taken over by an EMD GP9 diesel locomotive No. 7048, painted in PRR livery. [19] [20] On April 12, 1987, the locomotive moved under its own power for the first time in 31 years and made its first excursion run from Altoona to Bellefonte, Pennsylvania. [5]
In the 18th century the Kittanning Path passed through the gap, providing a route between central and western Pennsylvania for Native Americans and early white settlers. Why the gap is left of the Kittanning Run can only be speculated upon, but a topographical examination suggests for 16th-19th century peoples on foot or pulling a cart or Conestoga wagon, turning right up the gap would lead ...
Horseshoe Curve is a 3,485-foot (1,062 m), triple-tracked railroad curve on the Norfolk Southern Railway's Pittsburgh Line in Logan Township, Blair County, in the U.S. state of Pennsylvania. It is close to 1,300 feet (400 m) in diameter and has a grade of almost two percent.
Leaving Altoona, the railroad travels at a 1.76% grade up the east slope of the Alleghenies, negotiating the famous Horseshoe Curve during that climb. Past the curve, the Pittsburgh Line continues to climb a grade of 1.86% to the small town of Gallitzin , where the mainline reaches the top of its climb at 2,167 feet (661 m) above sea level, the ...
