TheSD20-2 was a type ofdiesel-electric locomotive created in 1979/1980 by theBaltimore and Ohio Railroad by rebuildingEMD SD35 locomotives.^[1] Five of the B&O's SD35 fleet were rebuilt at their Cumberland Yard by fitting a non-turbochargedEMD 645 engine and upgraded electrical systems.^[2] They were placed in service at theB&O Queensgate Yard inCincinnati, Ohio attached toslugs, engineless units withtraction motors that draw their power from the "mother" unit.

With the B&O, the SD20-2s were numbered #7700–7704. At some point, #7700 and #7702 swapped numbers. All of them passed toCSX Transportation as #2400-2404, but are now withdrawn from CSX service. One of the units, #2401, went on to theOhio Central Railroad System; #2401 was in turn resold to thePacific Harbor Line and reassigned road #45 (pictured at right). #2404 wasscrapped byCycle Systems ofRoanoke, Virginia in August 2006.^[2]
