The Lehigh Valley Railroad was a major American railroad that operated primarily in the northeastern United States. Founded in 1855, it connected key cities such as Allentown, Bethlehem, and Easton in Pennsylvania, facilitating the transport of coal, iron, and other goods. The railroad played a significant role in the industrial growth of the region. At its peak, the Lehigh Valley Railroad expanded its network, reaching as far as New York City and Buffalo. It was known for its distinctive red and yellow locomotives and was a key player in the transportation of freight and passengers until its decline in the mid-20th century.
