The '''Alstom Metropolis C830''' are the second generation of communication-based train control (CBTC) rolling stock to be used in [[Mass Rapid Transit]] (MRT)  lines. Alstom was contracted in 2000 (as part of turnkey contract C830) by the Land Transport Authority (LTA) in Singapore to supply the trains for the [[Circle Line]].
==Fleet Numbering==
 
The car numbers of the trains range from 801x to 840x, where x depends on the carriage type.
The automated system version, previously known as "moving block systems", CBTC systems 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.
*The last digit identifies the position of the car from the front end of the train; where ‘1’ represents first car, ‘2’ represents second car and ‘3’ represents third car.
 
**(Example) Passenger Vehicle 33 (also 833) would consist of 3 cars with serial number 8331, 8332, 8333 respectively.
Despite being similar to the fully underground [[North East Line]], the decision was made to power the three-car trains along the upcoming [[Circle Line]] by third rail instead of overhead catenary. 40 trainsets of three cars each were purchased for the [[Circle Line]]. LTA says that they will be adding 16 new trains to the [[Circle Line]] by 2015.
*Depending on the direction of travel, the sequence may be reversed.
 
These cars, although similar to their [[Alstom Metropolis C751A|counterparts running on the North East Line]], do not feature LCD displays in each car. Also, the front of the train features an extra window cut into the emergency exit door, something lacking in the [[Alstom Metropolis C751A|North East Line trains]]. In addition, due to its driverless configuration, there are windows at the front and back of the train, giving passengers a view of the tunnel as the train speeds through.
 
==Fleet==
[[C830 Fleet Info]]
 
==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 Corporation]].
* 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.
 
A typical SMRT Circle Line train (in this case, Set 30 aka 830, 301/303 or 301/302/303), would consist of serial numbers 8301, 8302, 8303.

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.

History[edit]

Alstom Transport was awarded Contract C830 in 2000 and 2002 for the construction of 120 passenger cars in 3 batches.[1]

Fleet Numbering[edit]

The car numbers of the trains range from 801x to 840x, where x depends on the carriage type.

  • The last digit identifies the position of the car from the front end of the train; where ‘1’ represents first car, ‘2’ represents second car and ‘3’ represents third car.
    • (Example) Passenger Vehicle 33 (also 833) would consist of 3 cars with serial number 8331, 8332, 8333 respectively.
  • Depending on the direction of travel, the sequence may be reversed.
