the FEC is its transportation of high-grade limestone, which is used in the formulation for concrete and other construction purposes. The limestone is quarried near Miami in the "Lake Belt" area of Dade County and Broward County just west of Hialeah. The rock trains come out of the FEC yard at Medley in Miami-Dade County and the southern end of the FEC service area. Shipments currently are principally for materials dealers Titan and Rinker. Rinker has since been sold and is now part of the multi-national Cemex. Rock train traffic dropped dramatically in 2008 with the elimination of all but one dedicated rock train. Other rock loads are now added onto other regular trains. Up until mid 2017, only one rock train remained, which is called the "unit train" and operates between Miami and City Point. Since then, rock traffic has rebounded, and the railroad has since added a second unit rock train which handles Ft. Pierce bound rock. Intermodal services The intermodal traffic includes interchanged shipments with CSX and Norfolk Southern, participation in EMP container service operated by UP and Norfolk Southern, United Parcel Service (UPS) piggyback trailers, trailers going to the Wal-Mart distribution center at Fort Pierce, and intermodal shipping container traffic through the ports of Miami, Port Everglades (adjacent to Ft. Lauderdale, Florida, and the principal source of imports), Port of Palm Beach/Lake Worth Inlet, and Port Canaveral. Additionally FEC offers "Hurricane Service" offering trucking companies the opportunity of having their trailers piggybacked out of Jacksonville to save the expensive cost of back-hauling empty trailers. Starting in 2012 the FEC began an aggressive project to reopen direct rail service to the ports of Miami, and Port Everglades. This is in anticipation of the expansion of the Panama Canal and the expected increase of intermodal traffic. In 2013 the drawbridge at the Port of Miami was repaired and reactivated and trains began to roll. In 2014 a new container shuttle was put into operation between Hialeah Yard and the Port of Miami. Also in 2014, the new rail lines into Port Everglades were opened, allowing direct access for FEC trains into the port. Further, a new transfer facility in Hialeah Yard will add additional intermodal transfer between trains, trucks, and planes. This facility opened in 2015. Additional capacity improvements are planned at other ports as well as the FEC's mainline. Other freight The FEC also hauls normal "manifest"
