Manufacturing process
Kawasaki will be responsible for the overall project management, design, manufacturing of bogies and procurement of major components. CSR Sifang will be in charge of manufacturing, final fitting and assembly of complete MRT trains and factory testing. Kawasaki (Singapore) will be responsible for the delivery of complete MRT trains to the depot, on-site testing and commissioning. The new MRT trains are scheduled to be delivered to Singapore from 2015 onwards.
Main Propulsion Controller
The C151B trains is the fourth commuter type Electric Multiple Unit (EMU) made in Japan to feature electric systems fully manufactured by Fuji Electric. Propulsion is controlled by VVVF Inverter with 2-level IGBT semiconductor controller, rated at 415 kVA. Each inverter unit controls two motors on one bogie (1C2M), and one motor car features two of such units. Motors are three-phase AC induction type, model MLR109, with a maximum output of 140 kW.
Train Formation
The configuration of a C151B in revenue service is DT-M1-M2-M2-M1-DT
The car numbers of the trains range from x601 to x690, where x depends on the carriage type. Individual cars are assigned a 4 digit serial number by the rail operator SMRT Trains. A complete six-car trainset consists of an identical twin set of one driving trailer(DT) and two motor cars(M1 & M2) permanently coupled together. For example, set 665/666 consists of carriages 3665, 1665, 2665, 2666, 1666 and 3666.
Livery
Currently, it is the second train with SMRT's new white livery with red, yellow and black colour scheme, which is similar to Bukit Panjang LRT's C801A, as compared to the older SMRT trains. The C151B will be the third batch of trains to feature the classic white exterior background, similar to the Siemens C651 and the C151 trains prior to its refurbishment between 2006 and 2009. The C151B trains are the first trains to have a full white front unlike the older batch of trains with black front. The first two trains received the new livery with the older SMRT logos, while subsequent trains were painted with new SMRT logos.
