Alstom Metropolis C830

The Alstom Metropolis C830 trains are the first generation of rolling stock for the Circle Line. It is also the second generation of Communication-Based Train Control (CBTC) rolling stock in Singapore.

There are 40 trains of three cars each and have been in passenger service since 28 May 2009. The trains are housed in Kim Chuan Depot.

The automated CBTC system version, previously known as the "moving block system", do not require traditional "fixed-block track circuits" for determining the train position. Instead, they rely on "continuous two-way digital communication" between each controlled train and the control centre.

History

Contract 830 for the design and building of the trains was awarded to french company Alstom Transport.

The C830 trains are similar to the Alstom Metropolis C751A counterparts on the North East Line, utilising Alstom's Urbalis 300 CBTC system. However, the C830 trains receive power from the third rail instead of the overhead catenary. The LCD screens found on board the C751A trains were also depreciated in the C830 trains. The trains feature an additional viewing space on the detrainment door at both ends of the train, allowing passengers a view of the tunnel while on board.

40 trains of three cars each were bought by the Land Transport Authority for the five stages of the Circle Line, which commenced service on 28 May 2009 with the Circle Line Stage 3.
