The Lehigh Valley Railroad was a railroad built in the Northeastern United States to haul anthracite coal from the Coal Region in Pennsylvania. The railroad was authorized on April 21, 1846, for freight and transportation of passengers, goods, wares, merchandise and minerals in Pennsylvania and the railroad was incorporated and established on September 20, 1847, as the Delaware, Lehigh, Schuylkill and Susquehanna Railroad Company. On January 7, 1853, the railroad's name was changed to Lehigh Valley Railroad. It was sometimes known as the Route of the Black Diamond, named after the anthracite it transported. At the time, anthracite was transported by boat down the Lehigh River. The railroad ended operations in 1976 and merged into Conrail along with several northeastern railroads that same year. The Lehigh Valley Railroad's original and primary route between Easton and Allentown was built in 1855. The line later expanded past Allentown to Lehigh Valley Terminal in Buffalo and past Easton to New York City, bringing the Lehigh Valley Railroad to these metropolitan areas. By December 31, 1925, the railroad controlled 1,363.7 miles of road and 3,533.3 miles of track. By 1970, this had dwindled to 927 miles of road and 1963 miles of track. Conrail maintained the line as a main line into the New York City area. The line became known as the Lehigh Line during Conrail ownership. Conrail abandoned most of the route in New York State to Buffalo after 1976, considerably shortening the line. The majority of the Lehigh Line is now owned by the Norfolk Southern Railway (NS) and retains much of its original route in eastern Pennsylvania and New Jersey, although it no longer goes into New York City. The former Lehigh Valley tracks between Manville, New Jersey, and Newark are operated separately by Conrail Shared Assets Operations as their own Lehigh Line. History 1846–1860 The Delaware, Lehigh, Schuylkill and Susquehanna Railroad (DLS&S) was authorized by the Pennsylvania General Assembly on April 21, 1846, to construct a railroad from Mauch Chunk, Pennsylvania, now Jim Thorpe, Pennsylvania, to Easton, Pennsylvania. The railroad would run parallel to the Lehigh River and break the Lehigh Coal and Navigation Company's monopoly on coal traffic originating in the Wyoming Valley. The railroad was chartered on August 2, 1847, and elected James Madison Porter its president on October 21. Little occurred between 1847 and 1851, save some limited grading near Allentown, Pennsylvania. All this changed in
