The Kawasaki Heavy Industries & CSR Qingdao Sifang C151A trains are the fourth generation of rolling stock for the North South and East West Lines.
35 trains of six cars each were purchased under contracts 151A and 151A (VO). The trains have been in passenger service since 27 May 2011 and are housed in Bishan, Ulu Pandan and Changi Depots.
The KSF trains were delivered in two batches - 22 trains were delivered in 2011-2012 and 13 trains were delivered in 2013-2014.

East West Line
Built 2011 - 2014
35 trains of 6 cars each, numbered 501/502 to 569/570
Contract 151A and 151A (VO) for the design and building of the trains was awarded to the consortium of Kawasaki Heavy Industries and CSR Qingdao Sifang on 6 May 2009 and in 2011.
Kawasaki Heavy Industries oversees the project and design while CSR Qingdao Sifang handles the manufacturing and testing of the rolling stock. It was the first successful joint venture between these two companies in the international market.
The first four KSF trains entered service on 27 May 2011, coinciding with the opening of the new platform at Jurong East.
The Land Transport Authority initially purchased the 22 KSF trains under contract 151A to complement with the Jurong East Modification Project, which will reduce the turnaround time for trains on the North South Line, and increasing capacity on the North South and East West Lines by about 15%. The additional 13 KSF trains were then purchased afterwards under contract 151A (Variation Order) in 2012 to further increase the capacity of the line.
22 KSF trains from the first batch commenced service in 2011 and 2012, while the additional 13 KSF trains were put into service in 2013 and 2014.
In 2016, the KSF 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.
The KSF trains carry a dark exterior livery: a dark background, with a red band down the middle, and a grey band at the bottom.
Similar to the KNS trains, the front of the train is slanted, giving it a more streamlined look.
The train numbers are displayed on a yellow LED display at the top of the right windscreen.
There are three colour schemes in the train cars, with each colour applied to two cars of the train.
From the train ends to the middle cars, they are coloured pink (with red), baby blue (with blue), and turquoise (with emerald).
The KSF trains came with more hand grips, wider seats and a wider stand back area near the doors.
Two wheelchair bays are located in the middle of every KSF train at doors 12 and 13.
The Emergency Communication Button is positioned lower, enabling wheelchair-bound passengers to gain access to the feature.
Three rows of hand grips are positioned along the aisles of the train cabins to provide standing passengers with increased support.
Red LED lights that are positioned above each door will light up when the doors are closing.
STARiS is installed in all KSF trains. The route-maps were built into the panel of the train and does not protrude out.
It provides commuters with their route information throughout their journey, and indicates which side the doors will open.
The plate lists the companies involved in the manufacture of the train, and also the year it was built.
It is located at both ends of the train.
Train 501/502 initially came with in-train panels advertisement of the Singapore Skyline, but has since been removed
