The Shanghai Alstom Metropolis C830C, together with the C751C are the third generation of communication-based train control (CBTC) to be used in Singapore’s Mass Rapid Transit (MRT) lines. 24 trainsets of 3 cars were manufactured by Shanghai Alstom Transport Co Ltd (joint venture of Alstom and Shanghai Electric), with deliveries from end June 2014.
The tender for trains under the contract 830C was opened together with another contract C751C for an additional 18 North East Line trains which was closed on 18 Jul 2011 with 5 bids. The Land Transport Authority has shortlisted all of them and the tender results was published on 1 Feb 2012.
The body shell is identical to its predecessor, the C830, with slight differences such as a larger SMRT logo up front but the interior is significantly different. The reserved seats are coloured red to distinguish them from normal seats. Navy blue and yellow coloured seats are installed in the driving motor cars (end carriages) while the seats in the middle car are khaki. The train is equipped with a propulsion system that is louder than its predecessor.
Other new designs include the inner layer of the doors finished in a Bluish-Grey colour, a new Visual Passenger Information System, similar to the C951, located above the doors and a new gangway design similar to the C751C.
To spot one of them, their headlights are luminously white instead of warm yellow installed on older trains to know whether is either C830 or C830C trains.
