Excerpt: ALCO RSD-1 Former Soviet Railways 20-09 (D 20-09) on exhibit at the railway museum in former Varshavsky terminal -- Saint Petersburg, Russia . Originally built by ALCO as a model RSD-1 in 1944 and exported to the USSR. The ALCO RSD-1 was a diesel-electric locomotive built by American Locomotive Company (ALCO). This model was a road switcher type rated at 1000 horsepower and rode on three-axle trucks, having a iC wheel arrangement. It was often used in much the same manner as its four-axle counterpart, the ALCO RS-1, though the six-motor design allowed better tractive effort at lower speeds, as well as a lower weight-per-axle. There were three different specifications issued that covered the RSD-1 model; E1645 and E1646 were for wartime production for the US Army, while E1641 was a post-war order for the Mexican National Railways (Ferrocarriles Nacionales de Mxico ). Seventy of the RSD-1s were shipped overseas to the Soviet Union during World War II, where they were classed as the Soviet Railways 20 (D 20) class, as part of the Allied war effort. These locomotives were also used on the Trans-Iranian Railway . The Soviets subsequently kept many of the RSD-1s after the war, adopting the design to form the basis of their own line of diesel locomotives. A dozen RSD-1s were sunk en route to the Soviet Union when the ship they were on was torpedoed by a German U-boat . The first 13 RS-1s were requisitioned by the US Army, returned to ALCO and rebuilt to RSD...
