Operation System

This system runs the trains and safely transports passengers to their destination. Each line is determined to provide safe and on-time services. This system manages all aspects of driving-related regulations.


Through regular inspection and maintenance and with technicians working around the clock with high-tech equipment, this system ensures that the railcars are safe for passengers.


For efficient operation, the state-of-the-art signal system transmits signals from ground level to the train to control the train’s speed, distance between trains, where to stop, when to open and close the doors, and so on.


To guarantee that passengers have a safe and pleasant trip, SMRT’s information communication division manages and operates three systems: (1) the Digital Transmission System (DTS), which is in charge of the information and communications network within SMRT, (2) the Video Transmission System (VTS), which makes sure that passengers get on and off the train safely through installed cameras at each station and thus prevents accidents, and (3) the Train Radio System (TRS), which allows wireless communication between the Total Traffic Control Center and the trains.


By automatically operating supply of electricity, the Electricity System ensures high-quality electric supply. This system utilizes a two-stage relay and network method to allow supply of electricity without power outages. Also, as the system automatically operates and supplies electricity, it varies supply according to electric load. Control lights are remote controlled automatically within the station according to time.


This system ensures that various facilities are in place in order to provide a pleasant atmosphere and convenient access to passengers. This includes air conditioning in stations and installing escalators where passengers need to walk more than two flights of stairs.


The Automatic Fare Collection (AFC) system allows automatic calculation of tickets sold and other data collection for automatic management of various accounting and statistical information. The AFC system provides the use of passes and RF transit cards.
The system that allows the use of passes is made up of the Ticket Office Machine (TOM), the Automatic Ticket Vending Machine (AVTM), the Automatic Gate Machine (AGM), an automatic machine that calculates additional fares, various electrical devices that collect statistical and accounting data, and various electric information signs to assist passengers. The system that lets passengers use the Ratio Frequency (RF) transit card is made up of the Ratio Frequency Automatic Gate Machine (RFAGM), which tallies prepaid and credit card transit cards to manage statistics, the RF recharging machine that allows passengers to recharge prepaid cards, RF electronic devices that allows data collection, and the RF machine.

With the Track / Construction system, the durability of Lines 5, 6, 7, and 8 was enhanced by increasing the weight of the rails from 50kg/m to 60kg/m. And by extending the rail segment up to 9.3km, passengers can enjoy a quieter ride. Using semi-permanent concrete increasing the durability of the tracks also cut maintenance costs. It also made cleaning easier.


This keeps track of not only the status of all the trains but also the facilities within each station.
This system operates around the clock to guarantee safe and on-time services to passengers.
