The Bombardier MOVIA C951 is the first generation electric multiple unit rolling stock in operation on the Downtown Line of Singapore's Mass Rapid Transit (MRT) system. The contract was won by Bombardier Transportation (now Alstom) and the rolling stock was built by Changchun Bombardier Railway Vehicles (joint venture of Bombardier Transportation and CNR/CRRC Changchun). Initially, the authorities had ordered 73 trains, although LTA had ordered an additional 15 trains and a final 4 more trains under C951A which makes a total of 92 trainsets were manufactured under C951.
