Singapore Buses route 63

Service 63 is a trunk route connecting the residential estates of Kampong Ubi, MacPherson, Tiong Bahru and Bukit Timah to the central areas of Bugis, Clarke Quay and Chinatown. It is an important route between the Ubi Industrial Estate and Eunos MRT for many workers, and it also connects Rumah Tinggi and its surrounding Redhill estates with connections to Tiong Bahru MRT station.

With few services serving the Rumah Tinggi estate, this service links the estate to Tiong Bahru MRT. Also, demand between Ubi Industrial Estate and Eunos MRT is high during peak hours, and Service 63M helps to relieve some of that loading.
