Alstom Metropolis C830 are the first generation of trains running on the Circle Line. These trains were manufactured from 2006 to 2008 by Alstom Transport under the Contract 830.

Design

The trains are coloured in black and have a red stripe below it. As for the interior, the seats are purple, blue and green. The trains have a white top. Car 8042 has extra grabpoles installed as an effort by LTA to encourage more commuters to move towards the center of the car. But now all trains has extra grabpoles.

Serial number

Individual cars are given a four-digit serial number by the rail operator, SMRT Trains.

• The first digit of a car's serial number is always an eight.
• The other three digits is the train identification number. A full length train of three cars will have three different consecutive serial numbers. The second and third digits are used to identify the train, while the last digit denotes the carriage of each train. In a full length train, the numbers will end with 1, 2 and 3.

For example, set 833 would consist of serial numbers 8331, 8332 and 8333.
