The Kawasaki Heavy Industries & CRRC Qingdao Sifang T251 (Contract Turnkey 251) is the first generation electric multiple unit rolling stock in operation on the Thomson–East Coast line of Singapore's Mass Rapid Transit (MRT) system, manufactured by a consortium of Kawasaki Heavy Industries (KHI) and CRRC Qingdao Sifang (formerly CSR Qingdao Sifang) under Contract T251.

91 four-car medium-capacity trainsets were purchased by LTA for the Thomson-East Coast line in 2014 and the first set was delivered on 25 May 2018.

Seven additional trains were supposed to be procured for the RTS Link as both the Singapore and Malaysian governments agreed to both lines sharing largely identical technical specifications. Since then, a new agreement signed on 30 July 2020 meant that these trains would not be built and will be replaced by LRT trains.
