The route operates from Queen Street Terminal to Woodlands Train Checkpoint at Woodlands Centre Road, duplicating the local sectors of Bus Service 170 without crossing the border. Previously an ad-hoc service, it was formally introduced on Sunday, 27 December 2015, and operated daily.
Service 170A ceased operations on 19 May 2021, with the last day of service on 18 May 2021. The service was removed from the Land Transport Authority’s databases in end-May 2021, initially confirming its withdrawal. However, Service 170A was later re-added back to LTA’s databases on 19 June 2021, which indicates that this service may return after its period of indefinite suspension amid the COVID-19 pandemic.

Service 170A was a Short Trip Service variant of Bus Service 170, operating supplementary trips from Queen Street Bus Terminal to Woodlands Train Checkpoint without crossing the border into Johor Bahru. The route poster describes it as “to serve commuters’ travel needs better” — likely by improving headways and maintaining the reliability of Service 170’s local sectors without being affected by cross-border traffic conditions.
Despite the Downtown Line and the presence of duplicating bus routes along the Bukit Timah Road and Upper Bukit Timah Road corridors, the Land Transport Authority continued to keep Bus 170 reliable for commuters who need it. Formerly operating at irregular frequencies owing to congestion across the Causeway, dedicated buses on Service 170A would reliably ply the local sectors of Service 170 in both directions. Service 170A would terminate at Woodlands Centre Road (Woodlands Train Checkpoint) and then perform Service 170 back towards Queen Street Terminal.
‘Withdrawn’ in the early 2000s, there was no mention of Service 170A until its reappearance in 2014 as an ad-hoc service. Details were not published by SBS Transit although they operated on weekend evenings to ease the high demand between Little India and workers’ dormitories along Woodlands Road, using cross-border buses drawn from Service 170’s fleet.
The formal introduction of Service 170A was Sunday, 27 December 2015, when it was introduced as a full-day service, operating daily and alternating with Service 170 departures. The launch coincided with the opening of the Downtown Line (Stage 2) between Bukit Panjang and Bugis. Following the introduction of Service 170A, departures of Service 170 were reduced.
Bus Services 170, 170A & 170X towards Larkin, Woodlands Train Checkpoint & JB Sentral respectively regularly experiences a temporary route diversion along Woodlands Road, skipping Bus Stops 46021 – Bef W’Lands Ind Pk D St 2, 46031 – Kranji Lodge 1, 46041 – Opp Globalfoundries, and 46051 – Bef BKE due to traffic congestion. Refer to SBS Transit’s Twitter account for updates.
Mode of Operation
A full trip of Service 170A from Queen Street Terminal to Woodlands Centre Road (Woodlands Train Checkpoint) takes about one hour, and all passengers must alight at the terminating stop. The bus will then proceed to the next stop, Woodlands Centre Road (Blk 25), and begin its return journey towards Queen Street Terminal, operating as Service 170. For Bus Captains, 170A would be more of a loop service with little time to rest at the looping point.
Service 170A buses and their drivers operate independently of Service 170 despite the many similarities. Their buses do not cross the border, and as such, are able to use non-cross-border buses such as Mercedes-Benz Citaros. As such, local bus drivers can be deployed to Service 170A (SBS Transit is known to roster Malaysian drivers on cross-border services). Departures from Queen Street Terminal are staggered with its parent Service 170 to space buses apart.
2021 withdrawal / suspension amid COVID-19 pandemic
On 19 May 2021, Bus Service 170A abruptly ceased to operate, with no official notice issued by operator SBS Transit. The route suspension was initially believed to be temporary, due to Singapore’s transition to stricter safe distancing measures as part of Phase 2 (Heightened Alert) (16 May to 13 June 2021). However, all route information pertaining to Service 170A was removed from the SBS Transit website, Land Transport Authority website & the Land Transport Authority MyTransport.sg app on 30 May 2021. This confirmed the withdrawal of the service.
At the time, due to the Malaysia Movement Control Order, Service 170 had been plying the same route as Service 170A since 18 March 2020, looping at Woodlands Centre Road.
The last day of operation for Service 170A was 18 May 2021.
On 19 June 2021, Service 170A route information was restored on the SBS Transit website, Land Transport Authority website & the Land Transport Authority MyTransport.sg app. As such, Service 170A continues to be suspended until further notice.
