The Norfolk Southern Railway (reporting mark NS) is a Class I freight railroad operating in the Eastern United States. Headquartered in Atlanta, the company was formed in 1982 with the merger of the Norfolk and Western Railway and Southern Railway. Today Norfolk Southern operates roughly 19,000 miles of track in more than twenty states, serving major industrial regions from the Midwest and Great Lakes to the Southeast and Mid-Atlantic. Its network connects key ports along the Atlantic Coast with inland manufacturing centers and distribution hubs, making it a critical part of the nation's freight transportation system. Norfolk Southern handles a diverse mix of traffic including intermodal containers, automotive shipments, agricultural products, coal, chemicals, metals, and consumer goods. Major corridors link cities such as Chicago, Detroit, Pittsburgh, Harrisburg, Atlanta, Charlotte, and Norfolk, Virginia, while important terminals and yards support high-volume freight operations across the system. The railroad also became widely known for its participation in the 1998 division of Conrail, which expanded its presence in the Northeast and added important routes into states such as Pennsylvania, New Jersey, and New York. Powered primarily by modern diesel-electric locomotives from manufacturers like EMD and GE, Norfolk Southern trains move thousands of tons of freight daily across long-distance main lines and busy regional routes. With a strong emphasis on intermodal growth, infrastructure investment, and operational efficiency, the railroad continues to play a major role in connecting American industries to domestic markets and global trade through its extensive rail network.
