Kawasaki Heavy Industries C151 (KHI)

The Kawasaki Heavy Industries C151 trains are Singapore's first generation of rolling stock.

It is the oldest rolling stock in SMRT's train fleet and have been in passenger service since 7 November 1987. The trains are housed in Bishan, Ulu Pandan, Changi and Tuas Depots.

There are currently 66 trains of six cars each. All of the 396 KHI cars are built from 1986 to 1989 with no comparable differences by the four manufacturers in the consortium led by Kawasaki Heavy Industries.

These trains also underwent a Mid-Life Refurbishment programme between 2006 to 2008.

History

Contract 151 for the design and building of the trains was awarded to a consortium led by Kawasaki Heavy Industries, consisting of Kawasaki itself, Nippon Sharyo, Tokyu Car Corp and Kinki Sharyo.

It is worth noting that these C151 trains are the pioneer batch of mass transit trains in Singapore, which ran on the very first rapid transit line in Singapore. They entered service alongside the initial opening of the Mass Rapid Transit system on 7 November 1987.

Refurbishment and Upgrading

Between 2006 and 2008, these trains underwent a 2.5 year Mid-Life Refurbishment Programme which was done by Mitsui & Co, RM Transit Technology, Lexbuild and Rotem Company, at a total cost of S$142.7 million. By 2 January 2009, all of these trains have been refurbished.

From 2010 to 2013, these trains were put through an Upgrading and Improvement programme. Trains that were upgraded have new floorings, a large wheelchair symbol at the wheelchair bay as well as have its Builder and Refurbishment Plates fitted up.

Between 2014 and 2015, the KHI trains were upgraded to be equipped with Thales SelTrac Communications-Based Train Control (CBTC) signalling system under the Re-Signalling Project. With the upgrade, two seats from both ends of the train are replaced with a signalling box, housing the new signalling equipments.

It was announced on 4 July 2013 that new IGBT-VVVF Permanent Magnet Synchronous Motors (PMSM) from Toshiba will replace the original 4-Quadrant/GTO Chopper control from Mitsubishi Electric. With the new motors, power consumption is expected to be cut by 30%, operating noise levels will also be reduced by up to 12dB and the operating efficiency of the trains will be increased. Two trains undergone tests with the new motors between February and April 2015 in the depot, and on the main line in June and July 2015. The two trains entered revenue service on 30 July 2015 with the new motors. The contract for the full-fleet rollout was then awarded in January 2016 and the PMSM system will be rolled out to the other 64 KHI trains by December 2019. As of September 2017, only six trains have been retrofitted with the new Toshiba motors.

Replacement of KHI trains

Plans for the End-of-Life upgrade for the KHI trains were put on hold on 26 October 2016 as the Land Transport Authority will be replacing all 66 KHI trains. Contract R151 for 66 replacement trains was awarded to Bombardier on 25 July 2018, and the new trains will be put into service from 2022.

Modifications

Modification of Handrails

Modification of Handrails

Handrails were modified as a trial by LTA to encourage more commuters to move towards the centre of the car.

This programme was experimented in train car 2105.

The trial was successful and it has been rolled out to the rest of the KHI cars.
