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.
