Kawasaki Heavy Industries C151 are the first generation of trains running on the North South Line and the East West Line. These trains were manufactured from 1986 to 1989 in batches by a Japanese consortium consisting of Kawasaki Heavy Industries, Nippon Sharyo, Tokyu Car Corp, Kinki Sharyo under the Contract 151. No visible differences can be found in any of these batches, which were built to agreed specifications.

The trains underwent mid-life refurbishment program from 2006 to 2008 by Hyundai Rotem. Certain trains also have its Traction Control replaced to further enhanced operations reliability.

History

The Japanese consortium of Kawasaki Heavy Industries with Nippon Sharyo, Tokyu Car Corp and Kinki Sharyo was awarded Contract 151 in 1984 at a cost of $581.5 million for the construction of 400 passenger cars.[1]

Refurbishment

On 3 September 2004, Hyundai Rotem, Mitsui, RM Transit Technology and dU LexBuild received an order to refurbish all 396 carriages at a cost of $142.7 million.[2] The works included the refurbishment of interior fixtures, the addition of wheelchair spaces, the upgrading of onboard communications equipment, enhancement of the public announcement system, and general improvement of the cars' appearance.[3] SMRT said the reasons for refurbishment were wear and damage of important components over the past two decades and water leaks from the air-conditioning system on some trains.[3] The company chose this option instead of buying new rolling stock, which would have cost S$792 million.[3] All trains has finished refurbishment in end-2008, marking the 2 years refurbishment programme.

Upgrading

Following the 2011 major train disruptions, SMRT announced it was replacing important engineering components on all C151 trains by 2019.[4] This included changing the existing Mitsubishi Electric propulsion system for the newer Insulated-gate bipolar transistor (IGBT) and Permanent Magnet Synchronous Motor (PMSM) propulsion system by Toshiba.[5]

In tandem with the replacement of the signalling system on the North South East West Lines with the newer Thales SelTrac signalling system, new equipment are installed in the passenger compartment of the trailer cars.[6]

Replacement

In October 2016, LTA announced that it will be calling for a tender of new trains to replace all C151 trainsets.[7]

For the time being, LTA will work with SMRT to improve the reliability of the 66 first-generation trains until their replacement trains are ready.

Fleet Numbering

The car numbers of the trains range from x001 to x132 (for Passengers Trains) and x301 to x302 (for Money Train), where x depends on the carriage type.

  • The first digit identifies the position of the car from the closest end of the train; where ‘3’ represents first car, ‘1’ represents second car and ‘1’ represents third car.
    • (Example) Passenger Vehicle 131/132 would consist of 6 cars with serial number 3131, 1131, 2131, 2132, 1132 and 3132 respectively.
    • (Example) Passenger Vehicle 301/302 would consist of 4 cars with serial number 3301, 1301, 2301, 3302 respectively.
  • Depending on the direction of travel, the sequence may be reversed.
