Brewster Subdivision

From Bradley Junction, the line continues south to Agrock, Fort Green Springs, and Ona before coming to a point just north of Arcadia where it connects with the Seminole Gulf Railway, a shortline that operates the continuing track south to Punta Gorda and Fort Myers.

Four Corners Mine is located a short distance behind Agrock yard south of Bradley Junction.

It was built to further extend the Seaboard Air Line's network into the Bone Valley's growing phosphate industry.

[5] The Brewster Subdivision south of Bradley Junction was built by the Charlotte Harbor and Northern Railway (CH&N).

The Charlotte Harbor and Northern Railway was built in 1911, which intersected the Seaboard's branch at Bradley Junction.

The Charlotte Harbor and Northern Railway historically extended as far south as Boca Grande, which was once the location of a major phosphate shipping port.

In 1980, the Seaboard Coast Line's parent company merged with the Chessie System, creating the CSX Corporation.
