Norfolk Southern Corporation is a major freight railroad operator that owns and operates approximately 19,100 route miles of track across the Southeast, East, and Midwest United States, serving manufacturing plants, mines, distribution centers, and port facilities. The company generates revenue primarily through three commodity segments: merchandise freight (including agricultural products, chemicals, metals, and automotive goods), intermodal services (containers and trailers), and coal transportation for power generation and export markets. Norfolk Southern's business model relies largely on contract-based pricing and exempt shipments outside regulatory control, and the company competes with other railroads, trucking carriers, and water transport operators to serve industrial customers across diverse sectors.
