Alstom Metropolis C830C

The Alstom Metropolis C830C trains are the second generation of rolling stock for the Circle Line.

24 trains of three cars each were purchased and housed in Kim Chuan Depot and have been in passenger service since 26 June 2015.

These trains receive power through its current collector shoes, electrified by the third-rail electrification system alongside the running rails.

These trains come with new commuter-centric features such as additional overhead handgrips, platform gap fillers and dynamic route map displays.

These trains bear similarities to the first generation Alstom Metropolis C830 and its counterpart, the second generation Alstom Metropolis C751C, built during the same period.

Utilising Alstom's Urbalis 300 Communications-Based Train Control (CBTC) signalling system, these trains are capable of fully automated operations and can run without any train attendant on board.

24 trains of 3 cars each, numbered 841 to 864

The Alstom Metropolis C830C trains are maintained and operated by SMRT Trains.



Contract 830C for the supply of 24 new trains for the 30-station Circle Line (CCL) was awarded by the Land Transport Authority (LTA) to French train manufacturer Alstom Transport SA on 1 February 2012.

The purchase of 24 additional trains was part of efforts by the LTA to increase the capacity of the CCL by 60 per cent, boosting peak-hour train service frequencies.

All 24 trains were jointly manufactured by the French manufacturer and Shanghai Electric Group Co., Ltd. under Shanghai Alstom Transport Electrical Equipment Co., Ltd.

The first C830C train arrived in Singapore on 29 June 2014, with the first four trains entering passenger service on 26 June 2015.





Similar to the C830 trains, these trains sport a black livery and a red-colour strip throughout the whole train.

The design of the train is also curved, giving it a more streamlined look.

A yellow LED display at the top-left corner of the train's head is used to indicate the train numbers.

The train has brighter headlights compared to the first generation C830 trains.


There are three colour schemes in the train cars, with each colour applied to one car of the train.

The colour of the seats uses a single shade of yellow, grey and dark blue in the three different cars.

The reserved seats are differentiated with red colouring.



Platform Gap Width Reduction

The flooring edge of each train door is fitted with a rubber gap filler to reduce the gap between the train and the station platform.

This helps to reduce the risk of passengers in wheelchairs or with strollers slipping into or getting caught in the gaps.

Reserved Seats

The reserved seats, catered for commuters with special needs, are differentiated in red.

Wheelchair Bay

Two wheelchair bays are located in the middle car of every C830C train at doors 5 and 8.

Gangway Lights

Gangway spotlights are installed to illuminate the gangway area of the train cars.

Overhead Hand Grips

Three rows of hand grips are positioned along the aisles of the train cabins to provide standing passengers with increased support.

Grab-Handles at Doorways

Provide support for passengers boarding or alighting the trains and for passengers standing near the doors.

Door Closing Indicator

Yellow alert lights that are positioned above each door will light up when the doors are closing.

Builder Plate

The builder plate lists the companies involved in the manufacture and the built-year of the train.

Dynamic Route Map Display

The Dynamic Route Map Display panels provide commuters with their route information throughout their journey.

It also indicates which side the doors will open.

Train Traveller Information System

The LED display panels of the Train Traveller Information System show useful travel information, such as transcriptions of in-train announcements.

These displays are a wider version compared to the ones on the first generation C830 trains.

Viewing Space
+ Emergency Exit Ramps

Both ends of the train feature a viewing space and an emergency exit.

The viewing space allows passengers to view the tunnel through the windscreen.

The emergency exit ramp will be deployed in an emergency.

Emergency Communication Button
+ Door Unlock Handle

Emergency Communication Buttons are located at the side of the train doors to contact the train staff in an emergency.

The Emergency Door Unlock Handle is integrated with the panel.
