The CSX A Line forms the backbone of the historic Atlantic Coast Line Railroad Main Line, the backbone of their network in the southeastern United States. The main line runs from Richmond, Virginia to Port Tampa just southwest of Tampa, Florida, a distance of nearly 900 miles. With the exception of a short 61-mile segment in Greater Orlando (which is now state-owned), the entire line is still owned by Atlantic Coast Line successor, CSX Transportation.
