'''City Direct Service 664''' was a former service that provides residents of [[Tampines|Tampines East]] and [[Tampines|Simei]] with greater connectivity to the Central Business District (CBD). By running parallel to existing rail lines, the service provides a travel alternative for commuters who relied on the rail network and feeder buses to and from work. The route incorporates an express sector between Simei Street 3 and Central Business District via PIE, KPE & MCE.
