CSX Corp. is a U.S. freight transportation company built around its CSX Transportation rail network, which connects major population centers across the eastern United States and links to ports, terminals, and short-line railroads. Its core business is moving merchandise, intermodal containers and trailers, coal, and trucking-related freight services across a roughly 20,000 route-mile system. The company also owns several subsidiaries that extend the rail offering into bulk liquid chemicals trucking, intermodal terminal operations, automotive distribution, and rail-to-truck transload services. CSX’s operating model emphasizes scheduled service, asset utilization, and network reliability, with the goal of winning freight from trucking and other rail carriers while generating strong cash flow.
