Kawasaki Heavy Industries – Nippon Sharyo C751B, sometimes abbreviated to C751B or KNS 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. 21 trainsets of 6 cars each were purchased, and it is the first rolling stock to feature VVVF insulated-gate bipolar transistor traction control system. manufactured 66 cars and Nippon Sharyo manufactured 60 cars respectively with no comparable differences, having built to agreed specifications. These trains are the third generation of rolling stock to be used on the two lines. These trains were fitted with Mobitec MobiLED electronic destination displays for train run numbers.
The majority of these trains are operated on the North South Line with only a handful operating on the East West Line. It have $231million to pay C751B as a contract.
The front of the train sports a more slanted and streamlined look, with the run number display in Orange LED Display. The sides of the train, which is a standard livery, consists of a shiny black area covering the middle portion of the train from just above the windows to below the windows, followed by a bold red stripe and a thinner grey stripe at the bottom of the train.
All cars are equipped with 6 LCD per car (which have since been deactivated), and all except trainset 347/348 which features LED displays (which have been replaced by the VFDs of the STARIS). These used to show rail travel information, commercials and movie trailers. They also come with more grab poles, wider seats, more space near the doors and wheelchair space. The interior and exterior design of the train have been improved, incorporating a much sleeker design. The LED displays however have seen little usage after a new series of voice announcements were introduced across the system in mid-2008. All VPIS were removed to make way for the STARIS by 2010. In 2013, support bars are added to the seats with hand grips, and the middle handrails with hand grips are configured to join across nearly one carriage, as such all grabpoles that branched out into three are replaced by regular single grabpoles.
