The Changchun Bombardier Movia C951 is a type of train built for Singapore's Downtown Line. The contract was won by Bombardier Transportation and the rolling stock was built by Changchun Bombardier Railway Vehicles (joint venture of Bombardier Transportation and CNR Changchun) Initially, the authorities has 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.
The tender for trains under the contract turnkey 951 was closed on June 2008. The tender results was published on Nov 2008, with the winner in bold.
73 trainsets consisting of three cars each were purchased at a cost of approximately S$570.7 million for passenger service.Bombardier beat Alstom, Kawasaki Heavy Industries and Hyundai Rotem in the tendering process as the lowest cost offered.
Land Transport Authority later placed an additional order of 15 trainsets in 2013 at an approximate value of $119.2 million. LTA had increased the variation order from 15 to 19, therefore bringing the total trainsets to 92. A partial number of the total fleet operates on the Stage 1 of Downtown Line since 22 December 2013.
