The Kawasaki Heavy Industries & Nippon Sharyo C751B is the third generation electric multiple unit rolling stock in operation on the North–South and East–West lines of Singapore's Mass Rapid Transit (MRT) system since early 2000, manufactured by Kawasaki Heavy Industries & Nippon Sharyo (KNS) under Contract 751B. 21 trainsets of 6 cars each were purchased at S$231 million, and it is the first rolling stock to feature VVVF insulated-gate bipolar transistor traction control system. Kawasaki manufactured 66 cars and Nippon Sharyo manufactured 60 cars respectively with no comparable differences, having been built to agreed specifications. These trains are the third generation of rolling stock to be used on the two lines.
