Baltimore and Ohio SD20-2 Diesel-Electric Locomotive
The SD20-2 was a type of road switcher diesel-electric locomotive created in 1979/1980 by the Baltimore and Ohio Railroad by rebuilding EMD SD35 locomotives. Five of the B&O's SD35 fleet were rebuilt at their Cumberland Yard by fitting a non-turbocharged EMD 645 engine and upgraded electrical systems. They were placed in service at the B&O Queensgate Yard in Cincinnati, Ohio attached to slugs, non-powered units with traction motors that draw their power from the "mother" unit.
With the B&O, the SD20-2s were numbered Nos. 7700–7704. At some point, No. 7700 and No. 7702 swapped numbers. All of them passed to CSX Transportation as Nos. 2400-2404, but are now withdrawn from CSX service. One of the units, No. 2401, went on to the Ohio Central Railroad System; No. 2401 was in turn resold to the Pacific Harbor Line and reassigned road No. 45 (pictured above). No. 2404 was scrapped by Cycle Systems of Roanoke, Virginia in August 2006.
