The Kawasaki Heavy Industries & CSR Qingdao Sifang C151A, sometimes abbreviated to C151A or KSF C151A is the fourth generation Electric multiple unit rolling stock in operation on the North South and East West Lines of Singapore's Mass Rapid Transit (MRT) system. 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%.
The initial contract of 22 trainsets of 6 cars each was awarded to and CRRC 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 Line and East West Line to be painted in the original livery, including all Batch 2 trains even though they were made and painted in 2014.
On 5 July 2016, an investigative news report from FactWire alleged that C151A trainsets were being shipped back to Qingdao for rectification due to multiple defects, including an exploding battery and cracks on trains, but without notifying the public beforehand. The Singapore government acknowledged the trains were returned for rectification works, and have since published official statements to address FactWire's specific allegations.
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.
