and obtained the best ports (now known as Port Tampa). The South Florida's original passenger depot in Tampa was located on the east side of the intersection of Ashley and Madison Streets. The Tampa end opened on December 10, 1883, and on January 25, 1884 service began over the full line, built to narrow gauge. On February 20, 1886 the Jacksonville, Tampa and Key West Railway opened to Sanford, and the South Florida was converted to standard gauge on September 22. In 1893 the Savannah, Florida and Western Railway (Plant System) directly acquired the South Florida. Henry Plant died in 1899, which led his heirs to sell the Plant System to the Atlantic Coast Line Railroad in 1902. The Atlantic Coast Line would then designate the South Florida Railroad main line (along with the main line of the Jacksonville, Tampa and Key West Railway and other railroads to the north) as their nearly 900-mile main line from Richmond, Virginia to Tampa. In 1967 the Atlantic Coast Line merged with the Seaboard Air Line Railroad (who operated the former Florida Central and Peninsular Railroad, the South Florida's former competitor), becoming the Seaboard Coast Line Railroad. Seaboard Coast Line eventually became CSX in the 1980s, and the South Florida/Atlantic Coast Line main line now operates as part of one of its two main lines in the area, known as the "A" Line. In 2011, CSX sold the line from Poinciana north (as well as part of the former Jacksonville, Tampa and Key West Railway) to the Florida Department of Transportation. This state-owned segment is known as the Central Florida Rail Corridor, which includes most of the track that the SunRail commuter rail service operates on. SunRail began operation on May 1, 2014, from Sand Lake Road north to DeBary and extended service south to Poinciana on July 30, 2018. SunRail also revived passenger service to the South Florida Railroad's historic Church Street Station in Downtown Orlando. Lines Main Line When completed in 1884, the South Florida Railroad's main line ran from Sanford southwest through Orlando and Lakeland to Tampa, terminating at Port Tampa. The main line today runs south of and roughly parallel to Interstate 4. Some of the towns along the line were named for railroad officials. Plant City was named for Henry Plant, and Haines City was named for Colonel Henry Haines, who organized the construction of the line and
