The Atlantic Coast Line Railroad was a United States Class I railroad formed in 1900, though predecessor railroads had used the ACL brand since 1871. In 1967, it merged with long-time rival Seaboard Air Line Railroad to form the Seaboard Coast Line Railroad. Much of the original ACL network has been part of CSX Transportation since 1986.
