The Kawasaki Heavy Industries & Nippon Sharyo C751B trains are the third generation of rolling stock for the North-South and East-West Lines.
21 trains of six cars each were purchased and have been in passenger service since 8 May 2000. The trains are housed in Bishan, Ulu Pandan, Changi and Tuas Depots.
The KNS trains are the first to have VVVF Insulated Gate Bipolar Transistor traction control system as well as a visual passenger information system installed in the cars. It also uses a radial arm axlebox, bolsterless airspring bogie.
All of the 126 KNS cars are built with no comparable differences between Kawasaki Heavy Industries & Nippon Sharyo.
Kawasaki Heavy Industries & Nippon Sharyo C751B
Built 1999 - 2001
21 trains of 6 cars each, numbered 311/312 to 351/352
Contract 751B for the design and building of the trains was awarded to the consortium of Kawasaki Heavy Industries and Nippon Sharyo.
The KNS trains entered service on 8 May 2000 to cope with the growing demand on the North-South and East-West Lines, and to complement the Changi Airport Extension.
Between 2014 and 2016, the KNS 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 KNS trains carry a dark exterior livery: a dark background, with a red band down the middle, and a grey band at the bottom.
The front of the train is slanted, giving it a more streamlined look.
The train numbers are displayed on an orange LED display at the top of the right windscreen.
The KNS trains initially came with luggage racks installed. These racks were eventually removed and the area now serves as a wheelchair bay.
The wheelchair bays are located in every train car beside the door nearest to the centre of the train.
Three rows of hand grips are positioned along the aisles of the train cabins to provide standing passengers with increased support.
Provide support for passengers boarding or alighting the trains and for passengers standing near the doors.
STARiS is installed in all KNS trains.
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.
Emergency exits are located at both ends of the train.
The emergency exit ramp will be deployed in an emergency.
3 sets of screens for STARiS Version 2 have been installed on train car 3322.
The screens have been removed in 2016 and will be installed above the doors, on all trains, in the future.
Handrails were modified as a trial by LTA to encourage more commuters to move towards the centre of the car.
This programme was experimented in train car 2335.
The trial was successful and it has been rolled out to the rest of the KNS cars.
The Liquid Crystal Displays of the Visual Passenger Information System used to display advertisements, but they have since been turned off.
The LED Displays of the Visual Passenger Information System provides commuters with their route information. They have been removed in favour of STARiS.
