was considered to be Plant's most trusted employee. The main line remains in service and is today the southernmost segment of CSX's A Line CSX (Poinciana to Port Tampa) Carters Subdivision (Poinciana to South Lakeland) Lakeland Subdivision (South Lakeland to Mango) Tampa Terminal Subdivision (Mango to Port Tampa) Amtrak continues to operate passenger service on the line and uses it to reach Tampa Union Station. Amtrak's Miami-bound trains also travel the line to Auburndale and turn south on to the Auburndale Subdivision. Prior to the sale of the north end of the line to FDOT, the line was part of CSX's Sanford Subdivision from Auburndale north. Since the sale, CSX only operates local freight on the Central Florida Rail Corridor. Freight service on the CFRC is based out of Taft Yard in Pine Castle, which CSX still owns. All of CSX's through freight traffic to northern Florida now uses the adjacent S Line. The Florida Central Railroad, which connects to the Central Florida Rail Corridor in Downtown Orlando, also has freight trackage rights from its connection south to Taft Yard. Pemberton Ferry Branch Part of the agreement worked out by Henry Plant between the South Florida and the Florida Southern Railway specified that the South Florida would build the north-south Pemberton Ferry Branch. This branch began at a junction with the Florida Southern at Pemberton Ferry (known today as Croom), running south-southeast across the mainline at Lakeland to Bartow. South of Bartow, the Florida Southern continued to Punta Gorda, using trackage rights over the branch. The branch was completed in September 1884. Once the Bone Valley phosphate district was discovered near Lakeland, pressure increased to standard-gauge the line, and that was done on August 7, 1891. After the Plant System bought the South Florida, an extension was built north from Pemberton Ferry to Inverness, where the Plant System's Silver Springs, Ocala and Gulf Railroad continued north, which was completed in 1891. In the Atlantic Coast Line era, the north leg of the Pemberton Ferry Branch would serve as the southernmost segment of their R Line, which ran from DuPont, Georgia to Lakeland via High Springs. By the 1920s, the line was busy enough that the Atlantic Coast Line expanded the line north of Vitis Junction to double track to increase capacity. The line is also notable for being the location of the Great Train Wreck of 1956 in Pineola (just
