Open publisher page 0 citations

Abstract

The Horseshoe Curve, built in 1854 as part of a 250-mile line between Harrisburg and Pittsburgh, is the centerpiece of the Pennsylvania Railroad. Over the years, curves safety and efficiency was improved through technologies such as automatic block signaling, installed in 1900. The main line was expanded from two to three tracks in 1898, and from three to four in 1900. An access road was opened in 1932, allowing tourists to visit the trackside. The National Park Service designated Horseshoe a National Historic Landmark in 1967.
