was co-located with the now defunct Bryant Sugar Mill, which closed in 2017. The line crosses the St. Lucie Canal on a small lift bridge in Port Mayaca. The line then continues to follow the lake a short distance before turning northwest to a point known as Marcy. The line crosses CSX's Auburndale Subdivision at Marcy before continuing northeast directly to Fort Pierce, where it connects to the FEC. East side history When the FEC ran the east side, it referred to the line as their K Branch. It was the southernmost segment of the FEC's Kissimmee Valley Line to Lake Okeechobee, which originally branched off the FEC main line near New Smyrna Beach and ran south through the Kissimmee Valley. It reached Belle Glade by 1923, and was extended to the Miami Canal in Lake Harbor in 1929 to connect with the Atlantic Coast Line. Most of the Kissimmee Valley Line north of Marcy was abandoned in 1947, and the remaining track was connected to the FEC main line by way of a new track from Fort Pierce known as the Glades Cutoff. The SCXF began leasing the east side line from the FEC on March 2, 1998, and now fully operates the line from milepost K 15 (Cana) south, and has trackage rights into FEC's Fort Pierce Yard where the interchange takes place. Sugar Express In late 2016, U.S. Sugar reacquired USSC No. 148, a 4-6-2 steam locomotive that they previously owned from 1952 to the 1970s. U.S. Sugar originally bought it from the FEC, which ran the locomotive on its Key West Extension. After being reacquired from the Denver and Rio Grande Historical Foundation in Monte Vista, Colorado and a three-year restoration work performed by the FMW Solutions, the No. 148 locomotive now runs on recycled vegetable oil and began its first revenue service, pulling the last cane train of the 2019–2020 harvest season on May 28, 2020. The South Central Florida Express now runs the No. 148 locomotive as part of USSC's heritage tourist passenger train named the Sugar Express. During the summer months of 2021, U.S. Sugar acquired an ex-Wabash turntable from St. Louis, Missouri, which will eventually be used to turn the No. 148 locomotive around at Clewiston. In need of rolling stocks for the Sugar Express, U.S. Sugar leased the Georgia 300 observation car. They acquired an ex-Pennsylvania Railroad lounge car renamed from
