Service 189 is an inter-town route serving between Bukit Batok and looping at Clementi Ave 1, via Bukit Batok Neighbourhood 2, Bukit Batok Street 23, Clementi Avenue 6, Clementi MRT and Clementi Road.
The route is well patronized between the industrial areas around Bukit Batok Street 23 and Bukit Batok MRT, with Short Trip Service 189A performing supplementary trips during Weekdays AM Peak, and scheduled mid-route departures (“downroutes”) in the reverse direction during Weekdays PM Peak. The sector between Clementi MRT and Clementi Ave 1 receives moderate demand due to the area’s presently limited residential developments, but encounters high demand from students heading to the educational institutions along Clementi Avenue 1.
Formerly a Singapore Bus Service (SBS) route since the 1970s, the route was transferred to Trans-Island Bus Service (TIBS) in 2000 and has been operated by SMRT until its it was re-allocated to the Bus Contracting Model (Bulim Bus Package) in May 2016. High capacity articulated buses are deployed during weekday peak hours back then, and double-deck buses were deployed since 26 October 2015.
In 2014, SMRT Service 189 was involved in a small scale bus loading trial where buses were equipped with electronic displays beside the front door, which indicates when the next bus will arrive and the passenger loading onboard that bus. The trial was never expanded, and LTA subsequently released bus loading information for mobile apps in addition to expected time of arrival.
Fare: Charges basic distance fares. See Bus Fares.
