The body shell is identical to the C830 with slight differences such as a larger SMRT logo up front but the interior is significantly different.The colour motif is similar to the C951s which are serving the Downtown Line in which the reserved seats are red.

The end cars are equipped with navy blue and yellow seats while the middle car has khaki seats. <ref>{{Cite web |

The Shanghai Alstom Metropolis C830C, together with the C751C are the third generation of communication-based train control (CBTC) rolling stock 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),[1][3] with deliveries from end June 2014.[3]
History
The contract, worth S$134 million, was awarded to Alstom (as part of turnkey contract C830C) by the Land Transport Authority (LTA) in Singapore to supply additional trains for the Circle MRT Line.[4] Alstom won over Hyundai Rotem, Kawasaki Heavy Industries, Construcciones Y Auxiliar De Ferrocarriles and CSR Zhuzhou to secure the order.
Design
The body shell is identical to the C830 with slight differences such as a larger SMRT logo up front but the interior is significantly different.The colour motif is similar to the C951s which are serving the Downtown Line in which the reserved seats are red. Unlike the C830 which have the Pink and Green seats at the end cars while the Blue is in the middle. The end cars are equipped with navy blue and yellow seats while the middle car has khaki seats. [5] The train is also equipped with a louder propulsion system.
There are also other main design differences between the 2 trains including the inner layer of the doors finished in Bluish-Grey rather than white, a new Visual Passenger Information System, similar to the C951s and C751Cs, also known as Dynamic Route Map Display, located above the doors, 2 stickers at each end car and a new gangway design.
To spot one of them, their headlights are luminously white similar to C951 and C751C instead of warm yellow installed on older trains.
Driverless operation
The C830C 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.[6]
Train Formation
The configuration of a C830C in revenue service is Mc1-Tp-Mc2

The car numbers of the trains range from 841x to 864x, where x depends on the carriage type. Individual cars are assigned a 4 digit serial number by the rail operator SMRT Trains. A complete three-car trainset consists of one trailer(Tp) and two driving motor cars(Mc1 & Mc2) permanently coupled together. For example, set 864 consists of carriages 8641, 8642, 8643.
- The first digit is always a 8.
- The second digit and third digit identifies the set number
- The fourth digit is the car number.
- Alstom Shanghai Electric built sets 841-864
