Operator	(Sengkang – Hougang Bus Package)

SBS Transit Bus Service 151 is an inter-town bus service connecting Hougang town to the industrial estates along MacPherson Road, as well as schools in Bukit Timah and Kent Ridge.

Despite the moderate demand during off-peak hours, Service 151 sees a boost in demand during peak hours and school dismissal hours, as it passes by several key secondary and tertiary institutions along Bukit Timah Road and Clementi Road alongside Service 154. It is also heavily utilised by university students from National University of Singapore (NUS) as the only direct route to reach Bukit Timah and the outskirts of Toa Payoh, giving alternative options to connecting services 95 and 96.

In addition, Service 151 provides a unique direct connection between Hougang town centre and MacPherson, while complementing Service 87 between Hougang Avenue 3 and Hougang Central at the same time.
