Railroad lines in Jacksonville were largely built at the end of the 1800s.

CSX's A Line north of Jacksonville (which leads to the Nahunta Subdivision) was originally part of the East Florida Railway. The A Line south of Jacksonville (which leads to the Sanford Subdivision) was part of the Jacksonville, Tampa and Key West Railway. Both lines became part of the Plant System and later the Atlantic Coast Line Railroad.

The S Line from Jacksonville west to Baldwin Junction was part of the Florida Central and Peninsular Railroad, which became part of the Seaboard Air Line Railroad.

With a large number of railroads operating in Jacksonville, the Jacksonville Terminal Company was chartered in 1894 to coordinate train movement of multiple railroads in the area, manage yards, and build Jacksonville Union Terminal, which opened in 1919. By 1902, the Jacksonville Terminal Company and the Union Terminal were jointly owned by five railroads. The Atlantic Coast Line Railroad, Seaboard Air Line Railroad, and Florida East Coast Railway each owned 25% of the company, and the Southern Railway and the Georgia Southern and Florida Railway each with 12.5% ownership.[3] The Jacksonville Terminal Company ceased operations in 1976 when the Union Terminal closed and Amtrak opened its current Jacksonville station on the northside of town.[4]

In 1967, the Atlantic Coast Line Railroad and Seaboard Air Line Railroad merged to form the Seaboard Coast Line Railroad. In the late 1970s, the Seaboard Coast Line built Duval Yard and Intermodal Ramp and associated tracks on the northwest side of town. Duval was built to handle intermodal traffic, since the areas other yards were too overcrowded by then. Duval Yard is connected to the A Line on the north end and the S Line on the south end.[5]

Seaboard Coast Line became CSX Transportation in 1986 after merging with the Chessie System. Norfolk Southern and the Florida East Coast Railway have trackage rights on CSX to interchange with one another and with CSX at Moncrief Yard.
