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.
The automated CBTC system on board relies on "continuous two-way digital communication" between each controlled train and the control centre.
Alstom Metropolis C830C
Built 2014 - 2016
24 trains of 3 cars each, numbered 841 to 864
Contract 830C for the design and building of the trains was awarded to french company Alstom Transport on 1 February 2012.
The trains are designed by Alstom Transport and manufactured by Shanghai Alstom Transport and Shanghai Alstom Electrical Equipment. The trains are similar to the first generation Alstom Metropolis C830 trains on the Circle Line. The first four C830C trains entered service on 26 June 2015.
The 24 additional trains for the Circle Line is an effort by the Land Transport Authority to increase the capacity of the line by 60%, thus boosting the train frequencies during the peak hours.
The exterior of the train is similar to the C830 trains, with a black livery and a red strip through 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 bottom of each doors have a gap reducer made of rubber that protrudes out, reducing the platform-train gap.
This helps to prevent passenger accidents due to the platform gap.
The reserved seats, catered for commuters with special needs, are differentiated in red.
Both ends of the train feature a viewing space and an emergency exit.
The viewing space allows passengers to have a view of the tunnel through the windscreen.
The emergency exit ramp will be deployed in an emergency.
Spotlights are installed to illuminate the gangway area of the train cars, and increases visibility during emergencies.
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.
The dynamic route map display panels provide commuters with their route information throughout their journey.
It also indicates which side the doors will open.
The Train Travel Information System shows useful travel information to passengers, such as the current and next train stations which the train will call at, the terminal station and other useful travel messages.
These displays are a wider version of the ones found on the C830 trains.
