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. The Atlantic Coast Line served the Southeast, with a concentration of lines in Florida. Numerous named passenger trains were operated by the railroad for Florida-bound tourists, with the Atlantic Coast Line contributing significantly to Florida's economic development in the first half of the 20th century. At the end of 1925, ACL operated 4,924 miles of road, not including its flock of subsidiaries; after some merging, mileage at the end of 1960 was 5,570 not including A&WP, CN&L, East Carolina, Georgia, Rockingham, and V&CS. In 1960, ACL reported 10,623 million net ton-miles of revenue freight and 490 million passenger-miles. History Early history The earliest predecessor of the ACL was the Petersburg Railroad between Petersburg, Virginia and a point near Weldon, North Carolina, founded in 1830. A route between Richmond, Virginia and Petersburg was built by the Richmond & Petersburg Railroad, which was founded in 1836. In 1840 the Wilmington and Weldon Railroad, at the time known as the Wilmington and Raleigh and renamed in 1855, completed a route between Weldon and Wilmington, North Carolina. From Wilmington, the Wilmington and Manchester Railroad began operations in 1853 to Florence, South Carolina, where the Northeastern Railroad operated to Charleston, South Carolina. In 1871, the W&W and the W&M (renamed the Wilmington, Columbia & Augusta) began using the Atlantic Coast Line name to advertise the two lines. An investor from Baltimore, William T. Walters, gained control of these separate railroads after the Civil War, and operated them as a network of independent companies. In 1897–98, most of the South Carolina lines in Walters' system were consolidated under the name of the Atlantic Coast Line Railroad Company of South Carolina. In 1898, as the companies moved towards combining themselves into a single system, the lines in Virginia were combined into the new Atlantic Coast Line Railroad Company of Virginia, and the lines in North Carolina underwent a similar process in 1899, becoming the Atlantic Coast Line Railroad Company of North Carolina. In 1899 or 1900, due to a regulatory climate in Virginia that was better suited to the company
