"The SD20-2 was a type of 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, engineless units with traction motors that draw their power from the \"mother\" unit."@en . .
