The Kawasaki Heavy Industries & CRRC Qingdao Sifang T251 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 and CRRC Qingdao Sifang (formerly CSR Qingdao Sifang) under Contract Turnkey 251.
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 scheduled to be procured for the Johor Bahru–Singapore Rapid Transit System that will connect Malaysia to Singapore, as the Malaysian and Singaporean governments agreed to largely identical technical specifications for both lines. In 2019, Malaysia proposed use of light rail vehicles instead, as part of efforts to cut costs. 8 vehicles were therefore purchased from CRRC Zhuzhou Locomotive Co.
