Matches in DBpedia 2014 for { ?s ?p The ALCO RSD-1 was a diesel-electric locomotive built by American Locomotive Company (ALCO). This model was a road switcher type rated at 1,000 horsepower (750 kW) and rode on three-axle trucks, having a C-C 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. It was developed to meet the Soviet demands of a locomotive with a lower axle load. On the other hand, due to the traction generator and appurtenant control apparatus being sized for four axles and yet having two additional powered axles, it had poorer performance at higher speeds.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 México).Seventy of the RSD-1s were shipped overseas to the Soviet Union in 1945 during World War II, as part of the Allied war effort. They were classed there as the Soviet Railways Да20 (Da20) class, also known after 1947 just as ДА (D for Diesel, A for Alco and 20 for axle load in tons). 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 TE1, TEM1 and TEM2. 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. According to Russian sources, 68 RSD-1 were received, and only two (Да20-41 and Да20-50) sunk on the way. Some were still in service in the 1980s.The first 13 RS-1s were requisitioned by the US Army, returned to ALCO and rebuilt to RSD-1s #8000-8012 for use on the Trans Iranian Railroad.
