The Alstom Metropolis C830 is the first generation of communication-based train control (CBTC) electric multiple unit rolling stock in operation on the Circle line of Singapore's Mass Rapid Transit (MRT) system since 2009. Alstom was contracted in 2000 (as part of turnkey contract Contract C830) by the Land Transport Authority (LTA) in Singapore to supply the trains for the Circle line.
