Siemens C651
 The Siemens C651 trains form a type of rolling stock that can be found on the North South Line and East West Line of the Mass Rapid Transit system in Singapore. A total of 114 cars were purchased and introduced from 1994 onwards. This is the only fleet retaining the white exterior bodies (just like the C151 trains before refurbishment) that are used on the North South Line and the East West Line.
