The Winston and Bone Valley Railroad was a railroad line running in the Bone Valley region of Central Florida. It connected to the South Florida Railroad main line (the current CSX A Line) near Lakeland. A vast majority of the line remains in service by CSX Transportation, who operates it today as their Bone Valley Subdivision.
History
Crossing of the Valrico and Bone Valley Subdivisions in Mulberry. Diamond is located in the median of State Road 37.
The Winston and Bone Valley Railroad began operations in 1892. It was founded by J.D. Griffin and William Mills Winn, who had operated a lumber mill just four miles northwest of Lakeland since 1884. They relocated the mill to a location four miles west of Lakeland in 1892. The location of this lumber mill became known as Winnston (named for Winn), which would later be shortened to Winston. Griffin and Winn built the Winston and Bone Valley Railroad to serve the lumber mill.
There was also heavy demand for rail service in the area's flourishing phosphate industry, and the 16-mile line also ended up serving many of the area's phosphate mines. The line was later leased to the Plant System in 1900, which also operated the nearby South Florida Railroad and Florida Southern Railway. The line was then extended to connect with the Florida Southern in Fort Meade. The lease was inherited by the Atlantic Coast Line Railroad (ACL) in 1902 when they took over the plant system. The ACL then bought out the line completely in 1909, designating it as their Bone Valley Branch.[1]
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.
Current Operations

What remains of the line continues to be operated today by CSX Transportation and is designated as their Bone Valley Subdivision. It connects to CSX's A Line and Winston Yard at the north end. At the south end, the track currently ends in Agricola at a wye with CSX's Agricola Spur (a former Seaboard Air Line track).[4][5]
The Bone Valley Subdivision crosses the Valrico Subdivision in Mulberry in the median of State Road 37. The line connects to the Valrico Subdivision (which is CSX's busiest route through the Bone Valley) through Mulberry Yard at Prairie Junction. The Bone Valley Subdivision also intersects with the Achan Subdivision in Achan.[5]
The Bone Valley Subdivision still serves a number of phosphate mines along its route between Achan and Agricola. Phosphate is generally brought from the mines to Winston Yard to be exported by rail throughout the country. Phosphate is also sent to Tampa to be exported by ship at Rockport Yard.[6]
Currently, Winston Yard at the north end of the line is CSX's primary classification yard for much of Central Florida. In addition to phosphate, the yard is used to stage manifest freight for much of the area. Winston Yard was expanded in the 1980s to fill the void when CSX closed their Lakeland Yard, which was located at the northwest corner of Lakeland Junction (located about four miles east of Winston).[7]
