Design
Exterior

The exterior colour of the train is black and are slanted, giving it a more streamline look with the run number display in Orange LED.
Interior

The colours of the seats are different from the other models. The C751B uses a sort of pinkish-purple pink, different shade of blue and bluish-green. They also come with more grab poles, wider seats.


The interior of the cars are all installed with Liquid Crystal Displays (6 in each car), and all except train 347/348 feature VPIS displays. Currently, the LCD had been turned off due to lack of demand and the VPIS was deactivated due to low reliability. The VPIS had since been removed due to installation of STARiS in 2010.
Wheelchair Space

They also come with more grab poles, wider seats; more standing space near the doors for and racks for luggage. These racks were eventually removed and now serve as a wheelchair area.
"Doors Closing" Indicator

Red LED lights that blink when doors are closing had been positioned at both corners of each door.

Additional grab poles and hand grips was trialled in Car 2335, as an effort by LTA to encourage more commuters to move towards the center of the car.

THEME: Peak
A typical peak period scenario in an MRT station includes heavy boarding and alighting activities, crowded trains despite decent frequencies, especially in interchange stations. Travel time is also usually longer than the what signboards in platforms stipulate given the huge crowd and other factors like train bunching.
