The Alstom Metropolis C751C together with the Alstom Metropolis C830C are the third generation of communication-based train control (CBTC) rolling stock to be used in Singapore’s Mass Rapid Transit (MRT) lines. 18 trainsets of 6 cars were manufactured by Shanghai Alstom Transport Co Ltd (joint venture of Alstom and Shanghai Electric),[1] Deliveries began in July 2014 and is expected to continue through 2015.[3][4][5]
As of 1 October 2015, the first trainset (7055/7056) has been deployed for service.
History
The contract, worth S$234.9 million, was awarded to Alstom (as part of turnkey contract C751C) by the Land Transport Authority (LTA) in Singapore to supply additional trains for the North East MRT Line. Alstom won over Hyundai Rotem, Kawasaki Heavy Industries, Construcciones Y Auxiliar De Ferrocarriles and CSR Zhuzhou to secure the order.
Design
Externally, the C751C is very similar to the older Alstom Metropolis C751A in terms of shape, color and appearance, but has a window on the evacuation doors located at the ends of the train so that passengers can see the track ahead, this is not included in the older C751A trains. The interior design is similar to the C751A but have redesigned gangway connections which is borrowed from the new C830C. The seats are similar to the newer Bombardier MOVIA C951 and C801A, being of a purplish tint. Priority seats are distinguishable by their red coloration. Its handgrips are now purple, a departure from the standard white most other rolling stock. The C751C has a dynamic route-map system, similar to the C830C and C951. It also has a louder and higher-pitched propulsion system, which bears an uncanny resemblance to the propulsion sound on the Kawasaki Heavy Industries C151. It is equipped with a new type of current collector.
Features
It features a Visual Passenger Information System, letting commuters know what the current and next station is, as well as green blinking lights which indicate the side of which the train doors will open when the train reaches the station. At most stations on the North East Line, the train doors will open on the right side, but at terminus stations like Punggol and HarbourFront, doors may open on the left.
Driverless operation
The C751C is fully driverless under normal circumstances, using CBTC which 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.[6]
Train Formation
The configuration of a C751C in revenue service is DT-Mp-Mi-Mi-Mp-DT

The serial numbers ranging from 7051/7052 ~ 7085/7086 are used by the operator, SBS Transit, to follow up with Alstom Metropolis C751A's train set numbers.
