Wilmington—Pee Dee Line

The Atlantic Coast Line Railroad's Wilmington—Pee Dee Line was a railroad line running from Wilmington, North Carolina west to Pee Dee, South Carolina (just west of Florence). Running in an east–west trajectory, it notably passed through Lake Waccamaw, Chadbourn, Nichols, and Mullins. Some of the line is still operating today.

History
The Wilmington—Pee Dee Line was built originally built by the Wilmington and Manchester Railroad in 1853. The Wilmington and Manchester's eastern terminus was originally just outside of Wilmington near Navassa (on the west side of the Cape Fear River). In 1866, the Wilmington and Manchester Railroad created the Wilmington Railway Bridge Company as a joint venture with the Wilmington, Charlotte and Rutherford Railroad (later known as the Carolina Central Railroad) to build a bridge over the Cape Fear River. The bridge, which was jointly owned by both railroads, was completed in 1867 allowing both railroad to extend into central Wilmington.

The Wilmington and Manchester Railroad was reorganized as the short-lived Wilmington and Carolina Railroad in 1870 and again as the Wilmington, Columbia and Augusta Railroad in 1877.

The Wilmington, Columbia and Augusta Railroad, along with the Wilmington and Weldon Railroad network and other railroads, were all considered to be part of the group of independent railroads known as the Atlantic Coast Line by the late 1890s. The lines were formally merged into the Atlantic Coast Line Railroad in 1898. Once under Atlantic Coast Line ownership, the company designated the former Wilmington and Manchester Railroad as the Wilmington—Pee Dee Line (part of their C Line) east of Pee Dee. The former Wilmington and Manchester west of Pee Dee was incorporated into the Atlantic Coast Line's Main Line and Florence—Robbins Line. Wilmington would also be the location of the Atlantic Coast Line's headquarters from 1900 to 1956.

The easternmost five miles of the Wilmington—Pee Dee Line from Navassa to Wilmington were jointly operated by the Atlantic Coast Line and their rival, the Seaboard Air Line Railroad (who absorbed the Carolina Central Railroad in 1900).

The Atlantic Coast Line would operate both passenger and freight service on the Wilmington—Pee Dee Line. By 1949, a daily local passenger train was running the full line from Wilmington (which ran to Sumter) in addition to a daily through freight train and a local freight train that ran six days a week. Passenger could also connect with passenger services on the Myrtle Beach Branch at Chadbourn.

In 1967, the Atlantic Coast Line merged with its rival, the Seaboard Air Line Railroad (SAL). The merged company was named the Seaboard Coast Line Railroad (SCL). Seaboard Coast Line continued operating the line as the Pee Dee Subdivision. By then, passenger service had been discontinued on the line. In the late 1970s, the Pee Dee Subdivision was abandoned between Whiteville and Malmo.

In 1980, the Seaboard Coast Line's parent company merged with the Chessie System, creating the CSX Corporation. The CSX Corporation initially operated the Chessie and Seaboard Systems separately until 1986, when they were merged into CSX Transportation. In the mid-1980s, the Pee Dee Subdivision was abandoned between the A Line (the former ACL Main Line) at Pee Dee and Mullins.

Current operations
Today, the line is still operating in two segments.

The remaining line from Mullins to Whiteville is today operated by the R.J. Corman Railroad Group

A short segment from Navassa to Malmo is still operating and is now CSX's Malmo Spur. The Malmo Spur connects with the Sunny Point Railroad which is operated by the United States Department of Defense and runs south to the Military Ocean Terminal Sunny Point.
