The Changchun Bombardier Movia C951/C951A is a type of train built for Singapore's Downtown Line. The contract was won by Bombardier Transportation[4] and the rolling stock was built by Changchun Bombardier Railway Vehicles (joint venture of Bombardier Transportation and CNR Changchun) [1][5][6] Initially, the authorities has ordered 73 trains,[6] although LTA had ordered an additional 15 trains[6] and a final 4 more trains under C951A which makes a total of 92 trainsets were manufactured under C951 & C951A.[3]


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.[5]


73 trainsets consisting of three cars each were purchased at a cost of approximately S$570.7 million for passenger service.[7] Bombardier beat Alstom, Kawasaki Heavy Industries and Hyundai Rotem in the tendering process as the lowest cost offered.[8][9]

Land Transport Authority later placed an additional order of 15 trainsets[10] in 2013 at an approximate value of $119.2 million.[11] LTA had increased the variation order from 15 to 19,[3] 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. All 92 trains had completed their manufacturing in Changchun Bombardier Railway Vehicles factory, with some of them awaiting for their delivery into Singapore by mid-2017.[3]


These trains are being delivered until 2017. They will be stabled at Gali Batu Depot, Kim Chuan Depot, Tai Seng Facility Building and the future East Coast Integrated Depot.

On 12 October 2012, the first of 11 trains for the Downtown Line Stage 1 arrived at Jurong Port and transported to Kim Chuan Depot to undergo testing by LTA before it is handed over to SBS Transit.[12]

By 28 February 2013, Bombardier had delivered nine of the 11 trains for Downtown Line Stage 1.[11] LTA together with the operator, SBS Transit conducted the necessary tests to ensure safety standards, functional performance and systems compatibility requirements are met before revenue service of the DTL1 which began on 22 December 2013.[13]



The C951/C951A trains include several features that were not seen in existing trains.[14]

New features include:

  • an ergonomic seat profile;
  • red reserved seats, which allows for clearer separation between normal and reserved seats;
  • perch seats, replacing the two-seaters at the ends of the car;
  • hand grips utilising joints instead of straps, providing commuters a steadier grip;

The train will also retain existing features like having two rows of poles and hand grips, and vertical poles which split into three at the center.

Dynamic Route Map Display[edit]

The Dynamic Route Map Display (DRMD) is a rail travel information system, newly introduced and developed for the C951/C951A trains. The dynamic route map display panels provide commuters with their journey status updates and route information. It also indicates which side the doors will open on. The Alstom Metropolis C830C and the Alstom Metropolis C751C feature the same DRMD.[15]

Platform Gap Width Reduction (PGWR)[edit]

The train doors have a frangible gap made of rubber that protrudes out. The platform-train gap will then be reduced from 75 to 40 mm, preventing passenger accidents due to the platform gap.[15]

LCD Displays[edit]

C951/C951A trains are also equipped with LCD Displays at each carriage, with a total of 18 LCD Displays on each train. They show advertisements, movie trailers and informercials related to the Downtown Line.

Train Formation[edit]

The configuration of a C951/C951A in revenue service is DM1-T-DM2

Cars of C951/C951A

DM1 23,650 77 ft 7.1 in
DM2 23,650 77 ft 7.1 in

The car numbers of the trains range from 9001x to 9092x, where x depends on the carriage type. Individual cars are assigned a five-digit serial number by the rail operator SBS Transit. A complete three-car trainset consists of one trailer (T) and two driving motor cars(DM1 & DM2) permanently coupled together. For example, set 903 aka 9003 consists of carriages 90031, 90032 and 90033.

  • The first digit is always a 9.
  • The second digit is always a 0
  • The third digit and fourth digit identifies the set number
  • The fifth digit is the car number.
