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.

c151は純銅に0.1％のジルコニウムを添加した銅合金です。単純な成分で高導電率を維持しつつ、強度と耐熱性を向上させることに成功しました。

C151 is a copper alloy obtained by adding 0.1% of zirconium to pure copper. It succeeded in improving strength and heat resistance while maintaining high conductivity with a simple component.

Alloy C151 was developed by Olin Brass for specific applications demanding high electrical conductivity and excellent resistance to stress relaxation at elevated temperatures.

The Kawasaki Heavy Industries & CRRC Qingdao Sifang C151C is the sixth generation electric multiple unit rolling stock in operation on the existing North–South (NSL) and East–West (EWL) lines of Singapore's Mass Rapid Transit (MRT) system, manufactured by a consortium of Kawasaki Heavy Industries (KHI) and CRRC Qingdao Sifang under Contract 151C.

The Kawasaki Heavy Industries & CSR Qingdao Sifang C151A is the fourth generation electric multiple unit rolling stock in operation on the existing North–South (NSL) and East–West (EWL) lines of Singapore's Mass Rapid Transit (MRT) system, manufactured by Kawasaki Heavy Industries (KHI) and CRRC Qingdao Sifang under Contract 151A.

The Kawasaki Heavy Industries C151 trains are Singapore's first generation of electric multiple unit (EMU) rolling stock model for the North-South and East-West MRT lines (NSEWL).

The Kawasaki Heavy Industries C151 is an electric multiple unit (EMU) train operating on the North South Line (NSL) and East West Line (EWL). Entering service in 1987 in tandem with the opening of Singapore’s Mass Rapid Transit (MRT) system, these trains are the oldest rolling stock currently in operation.

The C151 (Contract 151) is a Singaporean rapid transit electric multiple unit operated by the Singapore Mass Rapid Transit since November 1987 on the North-South and East-West Lines and the Changi Airport Extension.

2022年3月7日 · Decommissioning of the first-generation North-South and East-West Lines (NSEWL) trains, the Kawasaki Heavy Industries C151, began in June 2020. These trains are the oldest generation of rolling stock in Singapore, and their retirement marked the first time that local transport authorities had to dispose of old rolling stock.
