Norfolk Southern Corporation is a premier Class I freight railroad company operating primarily in the Eastern United States. Headquartered in Atlanta, Georgia, the company manages an extensive rail network spanning 22 states and the District of Columbia. In 2025, Norfolk Southern agreed to an $85 billion merger with Union Pacific to create the first transcontinental U.S. railroad, a transaction currently pending regulatory approval.
Norfolk Southern manages its business as one reportable operating segment (railway operations) with 2025 railway operating revenues of $12.2 billion diversified across three commodity groups — merchandise, intermodal, and coal. The 10-K does not disclose any single customer accounting for 10% or more of revenues, though it notes that concentration of customers in particular market segments or industries could reduce volumes during economic downturns.
