Design

Externally, the C751C shares similarities with its predecessor, the C751A in terms of shape, color and appearance, but has an additional window on the detrainment doors located at the ends of the train, allowing passengers to see the tracks ahead. The detrainment system on a C751C is also different than that of a C751A. The interior of the C751C is similar to the C751A but has redesigned gangways identical to those on the

. The seat colours are similar to the C951(A) and C801A, having a purplish tint. Priority seats can be identified by their red colouration. The C751C has a dynamic route-map system, similar to the C830C and C951. It also has a louder and higher-pitched traction motor than its predecessor, and is equipped with a new type of pantograph. The C751C trains utilise

Features

It features a Visual Passenger Information System, letting commuters know what the current and next station is, as well as green blinking lights which indicate the side of which the train doors will open when the train reaches the station. There is also a dynamic in-train route display, which provides commuters with their route information throughout their journey, and also indicates which side the doors will open. DRMD panels are installed in these trains, which will be slightly modified in 2024 to include Punggol Coast on the North East line extension. At most stations on the

Driverless operation

The C751C is fully driverless under normal circumstances, using CBTC which do not require traditional "fixed-block track circuits" for determining train position. Instead, they rely on "continuous two-way digital communication" between each controlled train and a wayside control center, which may control an area of a railroad line, a complete line, or a group of lines. Recent studies consistently show that CBTC systems reduce life-cycle costs for the overall rail property and enhance operational flexibility and control.

Train Formation

The configuration of a C751C in revenue service is DT–Mp–Mi+Mi–Mp–DT The car numbers of the trains range from 7x051 to 7x086, where x depends on the carriage type. Individual cars are assigned a five-digit serial number by the rail operator
