With the B&O, the SD20-2s were numbered #7700–7704. At some point, #7700 and #7702 swapped numbers. All of them passed to CSX Transportation as #2400-2404, but are now withdrawn from CSX service. Two of the units, #2401 and #2402, went on to the Ohio Central Railroad; #2401 was in turn resold to the Pacific Harbor Line and reassigned road #45 (pictured at right). #2404 was scrapped by Cycle Systems of Roanoke, Virginia in August 2006.
