The Kawasaki Heavy Industries & CSR Sifang C151A is the fourth generation and the currently newest rolling stock in operation on the East West Line and North South Line in Singapore until 2017 before the C151B will began operation. This additional batch of trains, together with a new track and platform at Jurong East Interchange, has increased the capacity of both lines by 15%.
22 trainsets of 6 cars each were awarded to and CSR Sifang by the Land Transport Authority. In 2013, a further order of 13 trainsets under Batch 2 was placed and as of 2014, all 35 trainsets have been officially put into revenue service.
This is the last batch of rolling stock on the North South MRT Line and East West MRT Line to be used in the original livery, including all Batch 2 Trains even though they were made and painted in 2014.
On May 6, 2009, the Land Transport Authority announced that Kawasaki Heavy Industries and CSR Sifang had won over Hyundai Rotem, Bombardier Transportation and Mitsubishi Heavy Industries to secure the contract at a cost of S$369 million, despite Hyundai Rotem offering the lowest bid at S$323 million for the order of 22 trainsets under Batch 1. CSR Sifang handled the manufacturing and testing of the rolling stock, while Kawasaki oversaw the project and design. The C151A contract was the first successful joint venture between these two companies in the international market.
The tender for trains under the contract turnkey 151A was closed in January 2009. The tender results were published in May 2009.
The C151A trains is the third 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-phrase AC induction type, model MLR109, with a maximum output of 140 kW.
