The Kawasaki Heavy Industries C151 is a type of train that is one of the four current types of electric multiple unit on the North South and East West Lines of Singapore's Mass Rapid Transit (MRT) system. These are the oldest trains built for the system; they were introduced in 1987 and are still in operation. Sixty-six trainsets consisting of six cars each and a single money trainset consisting of four cars were purchased and are operated by SMRT Trains. These trains were manufactured from 1986 to 1989 in batches by a Japanese consortium consisting of Kawasaki Heavy Industries, Nippon Sharyo, Tokyu Car Corp and Kinki Sharyo following a round of intense competitive bidding by rolling stock manufacturers from around the world. The trains underwent a two-year mid-life interior refurbishment programme by Hyundai Rotem. After 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, entered service in July 2015.
