The Kawasaki Heavy Industries & CSR Qingdao Sifang C151B is the fifth generation Electric multiple unit rolling stock in operation on the North South and East West Lines of Singapore's Mass Rapid Transit (MRT) system. 45 trains were purchased and all of them have been delivered to Singapore as of 12 April 2017.SMRT took delivery of the first 2 train cars on 21 May 2015. These trains will increase frequency for the two MRT lines, North South Line and East West Line.
These trains has a similar IGBT-VVVF traction system to the existing C751B and C151A and it is the first train to have a white front with a smaller logo. These trains are the first to be fitted with STARiS 2.0, which is embedded in the door's overhead panels, as factory stock and also the first amongst the rolling stock used on the North South Line and East West Line to have electric door actuators rather than the traditional pneumatic door actuators on previous generations of rolling stock, allowing smoother and more reliable door operations, reducing delays. The first C151B train 601/602 made its debut on the North South Line on 16 April 2017.
Some of the C151B trains are currently housed in Tuas Depot and will only begin revenue service on the East West Line (alongside with TWE) when the new signalling system is ready. As of now, the C151B trains are only serving the North South Line, where the new signalling system has been installed.
