The Kawasaki Heavy Industries & CSR Qingdao Sifang C151B is the fifth generation electric multiple unit rolling stock in operation on the existing North–South (NSL) and East–West (EWL) lines of Singapore's Mass Rapid Transit (MRT) system, manufactured by Kawasaki Heavy Industries (KHI) and CRRC Qingdao Sifang under Contract 151B. 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 increased frequency for the two MRT lines, North–South and East–West lines.
These trains retain the same IGBT-VVVF traction equipment found on the earlier C751B and C151A sets, also featuring SMRT's "Pixels" livery introduced on the Bukit Panjang LRT C801A, and was going to be on the refurbished C651 trains, until the project was cancelled in 2018. 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 and East–West lines 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 (Set 601/602) made its debut on the North–South Line on 16 April 2017.
Although there were some C151Bs housed in Tuas Depot since the inception of the Tuas West Extension, the C151Bs did not begin revenue service on the full-stretch of the East–West line only until 6 May 2018, when the line switched to the new signalling system. Before that, the C151Bs running on the EWL only ran on the Tuas West Extension between Gul Circle and Tuas Link as it was the only section that had the new signalling system installed. On 27 May 2018, with the complete transition to the new signalling system, all 45 C151B trains have entered service on the North–South and East–West lines.
