Alstom Metropolis Cars are the first generation of communication-based train control (CBTC) rolling stock that has been in use in Singapore’s Mass Rapid Transit (MRT) lines since 2003. Cctv Power Supply Facts | Cctv Power Supply Directory.

Alstom was contracted in 1997 and 1998 by the Land Transport Authority (LTA) in Singapore to supply for its North East Line in 2003, and subsequently for its Circle MRT Line, to be fully operational in 2010, excluding the Circle Line Downtown Extension.

Design features

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.
