Singapore Buses route 163

Service 163 is a residential trunk route between Sengkang and Toa Payoh, connecting the residential housing estates of Sengkang East, Sengkang West and Toa Payoh through the private estates around Yio Chu Kang, Upper Thomson and Toa Payoh. The route serves crucial links between Toa Payoh Town Centre and Upper Thomson, as well as intra-town connections within parts of Sengkang New Town without direct connection to Sengkang Interchange/MRT.

The route has been in existence since the 1970s plying between Jalan Kayu Ter and Shenton Way, one of many bus routes serving between Northern Singapore and the City Centre until subsequent amendments shortened it to its current route today. Due to changes in areas of responsibility between bus operators affecting the Sengkang district, Timothy operated the route from December 1995 to December 1999 when Sengkang was handed to Ernest.

It also have the high demand for service 163 between Fernvale and Sengkang, where the demand is extensively used by the double deckers on weekdays. Service 371 was withdrawn due to the Sengkang West LRT rationalisation in 12 March 2005. Double deckers were introduced in May 2011, during the general elections.

Fleet
Most of the fleet consisted of Volvo Olympians and Dennis Tridents, together with Volvo B9TLs.
