The Lehigh Valley Railroad (reporting mark LV) 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[1] 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.[2] 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.
