Alstom Metropolis C751A

The Alstom Metropolis C751A is the first generation of electric multiple unit rolling stock with communications-based train control on the North East Line of the Singapore Mass Rapid Transit, in operation since 2003. It was ordered under Contract 751A after GEC Alsthom, now Alstom, won the bid in January 1998, for 25 six-car trains. Unlike other Singapore MRT lines, it draws 1,500 V DC from overhead wires. It was the first fully driverless rolling stock in Singapore and uses Alstom's Urbalis 300 moving-block signalling. A mid-life refurbishment by CRRC Nanjing Puzhen began in 2019, and all 25 trains had been refurbished by February 2026.
