They are the last batch of rolling stock on the two lines to be painted in the "Blackbird" livery. Developed from the Kawasaki Heavy Industries & Nippon Sharyo C751B sets, further developments of the type include the C151B and C151C featuring design updates and changes. The C151A was the first rolling stock on the MRT network to be manufactured in China. The initial contract of 22 trainsets of 6 cars each was awarded to KHI and Sifang by the Land Transport Authority.
In 2013, a further order of 13 trainsets was placed, with all 35 trainsets in revenue service as of 2014.[7] In 2016, an investigative news report from Hong Kong's FactWire alleged that C151A trainsets were discreetly being shipped back to Qingdao for rectification due to multiple defects, including an exploding battery and cracks on trains. The Singapore government subsequently acknowledged the trains were returned for rectification works, and have since published official statements to address FactWire's specific allegations.
