The body shell is identical to its predecessor, the C830, with slight differences such as a larger SMRT logo up front and a different interior. The reserved seats are colored red to distinguish them from normal seats. Navy blue and lemon yellow coloured seats are installed in the driving motor cars (end carriages) while the seats in the middle car are khaki. [9] The train is equipped with traction motors louder than its predecessor, identical to those found on the M5 Series of the Amsterdam Metro.
Other changes include the inner layer of the doors finished in Bluish-Grey, a new Visual Passenger Information System, similar to that of C951(A), located above the doors and a new gangway design like the C751C.
The headlights on C830Cs are also much brighter than those on the C830s.
The C830C features a Visual Passenger Information System, letting commuters know what the current and next station is, as well as green blinking lights which indicate the side of which the train doors will open when the train reaches the station.
There is also a dynamic in-train route display, which provides commuters with their route information throughout their journey, and also indicates which side the doors will open. DRMD panels are installed in these trains, which will be slightly modified in 2026 to include Keppel, Cantonment and Prince Edward Road stations on the Circle line Stage 6.
At most stations on the Circle line, the train doors will open on the right side, but some stations like Promenade (Towards HarbourFront) and Bayfront (Towards Stadium) as well as the terminal stations like Dhoby Ghaut and Marina Bay, some trains may open their doors on the left.
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. [10]
Trainset 846 suffered from a faulty signalling hardware, resulting in intermittent signaling issues which caused widespread disruptions to the Circle MRT line for a week in both August and November 2016. [11]
The coupling configuration of a C830C in revenue service is Mc1–T–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 (T) and two driving motor (Mc) cars permanently coupled together. For example, set 841 consists of carriages 8411, 8412, 8413.
The Mass Rapid Transit system, locally known by the initialism MRT, is a rapid transit system in Singapore and the island country's principal mode of railway transportation. The system commenced operations in November 1987 after two decades of planning with an initial 6 km (3.7 mi) stretch consisting of five stations. The network has since grown to span the length and breadth of the country's main island – with the exception of the forested core and the rural northwestern region – in accordance with Singapore's aim of developing a comprehensive rail network as the backbone of the country's public transportation system, averaging a daily ridership of 3.45 million in 2023.
The North East Line (NEL) is a high-capacity Mass Rapid Transit (MRT) line in Singapore. Operated by SBS Transit, the 20-kilometre (12 mi) line is the MRT's shortest. It runs from HarbourFront station in southern Singapore to Punggol station in the northeast, serving 16 stations via Chinatown, Little India, Serangoon and Hougang. Coloured purple on official maps, it is Singapore's third MRT line and the world's first fully-automated underground driverless heavy rail line.
The Circle Line (CCL) is a medium-capacity Mass Rapid Transit line in Singapore. It runs in a loop from Dhoby Ghaut station in the city-centre to HarbourFront station in the south via Bishan station in the centre of the country. It also has a branch to Marina Bay station from Promenade station, which will be extended to HarbourFront station from 2026 to form a complete loop. Coloured orange on the rail map, the fully-underground line is approximately 35.5 kilometres (22.1 mi) long with 30 stations. Travelling from one end of the line to the other takes about an hour.
The Bukit Panjang LRT is a 8-kilometre (5.0 mi) automated guideway transit line in Bukit Panjang, Singapore. The BPLRT is currently the only LRT line operated by SMRT Trains. As the name suggests, it serves 13 stations in the neighbourhood of Bukit Panjang and parts of Choa Chu Kang in the north-west of the country. The line was the first LRT line constructed in Singapore, having opened on 6 November 1999 by Deputy Prime Minister Tony Tan.
The Alstom Metropolis is a family of electric multiple units designed and produced by the French rolling stock manufacturer Alstom. It is designed for high capacity rapid transit or metro rail infrastructure systems. Trains can be run in various configurations, the length alone varying between two and ten cars; it is also suitable for both manned or unmanned operations.

The Joo Koon rail accident, sometimes referred to as the Joo Koon train collision, was a crash which happened on 15 November 2017, when a C151A train travelling at 16 kilometres per hour (9.9 mph) rear-ended a stationary C151A train at Joo Koon station on the East–West MRT line, resulting in 38 injuries. The stationary train was in the process of being detrained due to a train fault. Both trains were operating under the recently installed Thales SelTrac CBTC signalling system at the time of incident, and the Minister of Transport Khaw Boon Wan expressed that he was "disturbed" by an initial finding that "critical safety software" was inadvertently removed from the stationary train, possibly due to a malfunctioning signalling circuit, which led to the crash. This incident is the second train collision in Singapore MRT's history, after the Clementi rail accident.
The Alstom Metropolis C851E is the third generation electric multiple unit rolling stock introduced on the existing North East and Circle lines of Singapore's Mass Rapid Transit (MRT) system, manufactured by Alstom under Contract 851E. It consists of six North East line trains and 23 Circle line trains. The trains will be manufactured and assembled in Alstom's manufacturing facility in Barcelona, Spain and progressively shipped to Singapore from 2021 for the NEL and 2022 for the CCL. The contract, valued at S$249,854,305.00, was awarded by the Land Transport Authority during a ceremony held at Sengkang Depot. Alstom is the sole bidder for this contract. An additional 12 3-car trains will be purchased for use on the Circle line, from 2024 onwards.
The Sydney Metro Metropolis Stock is a class of electric multiple units that operate on the Sydney Metro network.
