A former Tri-Rail GP49, now owned by Dieselmotive Company sits in the St. Mary's Railroad yard just outside St. Mary's. This unit was one of six used in commuter service in Southeast Florida for almost two decades. These were largely phased out now that Tri-Rail's F40s have returned to service, and only two still run on the line. As of mid-February, this unit was moved to the G&W-owned Bay Line, where it sits at their deadline in Panama City, FL.
