The Kawasaki Heavy Industries (KHI) C151 is the first generation electric multiple unit (EMU) rolling stock in operation on the North–South and East–West lines of Singapore's Mass Rapid Transit (MRT) system, manufactured by a consortium led by Kawasaki Heavy Industries (KHI) under Contract 151. They were first introduced in 1987 and are the oldest trains in operation on the network.
Sixty-six trainsets consisting of six cars each and a single money train set consisting of four cars were contracted in 1984. They were manufactured from 1986 to 1989 in two batches by a Japanese consortium consisting of the namesake Kawasaki, Nippon Sharyo, Tokyu Car Corp and Kinki Sharyo following a round of intense competitive bidding by international rolling stock manufacturers.
The trains underwent a two-year mid-life interior refurbishment programme by Hyundai Rotem. After the 2011 major train disruptions on 15 and 17 December 2011, further plans to upgrade its mechanical components to increase its reliability were made. The first trainset to receive this upgrade, which included a replacement traction system to PMSM, entered service in July 2015.
The R151 trains have been replacing all of the first-generation C151 trains since June 2023, with the latter to be entirely superseded by 2026.[12]
