Kawasaki Heavy Industries & CSR Qingdao Sifang C151B

The Kawasaki Heavy Industries & CSR Qingdao Sifang C151B trains are the fifth generation of rolling stock for the North-South and East-West MRT lines.

45 trains of six cars were purchased and have been in passenger service since 16 April 2017.

These trains receive power through its current collector shoes electrified by the third-rail electrification system alongside the running rails.

These trains come with new commuter-centric features such as additional overhead handgrips and the STARiS 2 liquid crystal displays integrated above each train door.

These trains are fitted with LED saloon lighting and electric-powered saloon doors compared to its predecessors that use conventional fluorescent saloon lighting and pneumatic saloon doors.

Utilising Thales' SelTrac Communications-Based Train Control (CBTC) signalling system, these trains are capable of fully automated operations with a train captain manning on board.

The Kawasaki Heavy Industries & CSR Qingdao Sifang C151B trains are maintained and operated by SMRT Trains.



Contract 151B for the design and building of 45 new trains for the North-South and East-West MRT lines (NSEWL) was awarded by the Land Transport Authority (LTA) to the consortium comprising Kawasaki Heavy Industries, Ltd. and CSR Qingdao Sifang Co., Ltd. on 23 August 2012.

Similar to the 2011-commissioned Kawasaki Heavy Industries & CSR Qingdao Sifang C151A trains, Kawasaki Heavy Industries oversaw the overall project management, design, manufacture of bogie and procurement of major components, whilst CSR Qingdao Sifang manages the manufacturing, final fitting, assembly and factory testing.

These trains were purchased to further increase the capacity of the NSEWL with re-signalling works between 2017 and 2018 and to cope with the projected increase in demand for the East-West Line (EWL) when the Tuas West Extension (TWE) opens in 2017.

The C151B trains are not equipped with the legacy signalling system, so they can only be deployed for passenger service on the North-South Line (NSL) until re-signalling works on the EWL are completed. As such, the first C151B train entered passenger service on 16 April 2017, together with the Sunday full-day trial of the upgraded signalling system.

Due to the service separation that isolates the TWE from the EWL in November 2017, several C151B trains are deployed onto the TWE until re-signalling works on the EWL are fully completed. On 6 May 2018, the C151B trains were deployed for the full-length of the EWL together with the commissioning of the upgraded signalling system.





The C151B trains carry the refreshed pixelated SMRT livery – a white livery base with a red-colour band that is sandwiched by black-and-yellow bands down the middle.

These trains have a similar car body shell to the C151A trains, albeit with different headlights.

A yellow LED display at the top-right corner of the train's head is used to indicate the train numbers.


There are three colour schemes in the train cars, with each colour applied to two cars of the train.

Similar to the C151A trains, from the train ends to the middle cars, they are coloured pink (with red), baby blue (with blue), and turquoise (with emerald).



Wheelchair Bay

Two wheelchair bays are located in the middle of every C151B train at doors 12 and 13.

The Emergency Communication Button is positioned lower, enabling wheelchair-bound passengers to gain access to the feature.

Gangway Lights

Gangway lights are installed to illuminate the gangway area of the train cars.

Overhead Hand Grips

Three rows of hand grips are positioned along the aisles of the train cabins to provide standing passengers with increased support.

Grab-Handles at Doorways

Provide support for passengers boarding or alighting the trains and for passengers standing near the doors.

Door Closing Indicator

Red warning lights that are positioned above each door will light up when the doors are closing.


STARiS 2 is integrated into all C151B trains, with LCD displays and LED door opening indicators built into the panels above all 48 train doors.

It provides commuters with their route information throughout their journey and indicates which side the doors will open.

Builder Plate

The builder plate lists the companies involved in the manufacture and the built-year of the train.

Emergency Exits

Emergency exits are located at both ends of the train.

The emergency exit ramp will be deployed in an emergency.

Emergency Communication Button

Emergency Communication Buttons are located at the side of the train doors to contact the train staff in an emergency.
