The '''EMC EA/EB''' is an early [[passenger train]]-hauling [[diesel locomotive]] built from May 16, 1937, to 1938 by [[Electro-Motive Diesel|Electro-Motive Corporation]] of [[La Grange, Illinois]] for the [[Baltimore and Ohio Railroad]].<ref>Pinkepank 1973.</ref>{{page needed|date=July 2016}} They were the first model in a long line of passenger diesels of similar design known as [[EMD E-unit]]s. Each locomotive unit developed {{convert|1800|hp}} from two {{convert|900|hp|abbr=on}} [[Winton Motor Carriage Company|Winton]] 201-A [[diesel engine]]s, driving the wheels through [[Diesel-electric transmission|an electric transmission]]—the [[Electrical generator|generator]] driven by each engine provided current for [[traction motor]]s. The locomotives were of [[AAR wheel arrangement#A1A-A1A|A1A-A1A]] [[wheel arrangement]]—two three-axle [[Bogie|trucks]] of which only the outer two [[axle]]s were powered. Six two-unit {{convert|3600|hp|abbr=on}} locomotives were produced, each consisting of a lead cab-equipped '''EA''' [[A unit]] and a cabless booster '''EB''' [[B unit]]. They were numbered 51 through 56; the A units bore the bare number and the B units the number followed by 'X'.
