Service 170A is parallel bus service supplementing trips of its parent cross-border Service 170 (Red Plate). Plying unidirectional from Queen Street Bus Terminal to Woodlands Train Checkpoint, the route duplicates the local sectors of Service 170 without crossing the border.
The route is designed to improve the reliability of its parent service 170 without sacrificing existing scheduled trips. Despite the Downtown Line and the other bus routes it duplicates along the Bukit Timah and Upper Bukit Timah corridor, The Land Transport Authority continued to keep Bus 170 reliable for commuters who need it. Formerly operating at dismal frequencies owing to congestion across the Causeway and dodgy timekeeping, dedicated buses now reliably ply the local sectors of Service 170 in both directions. Hence was the need for Service 170A, differentiating the local buses from the cross-border buses by terminating at Woodlands Centre Road (Woodlands Train Checkpoint) before returning to 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‘Withdrawn’ in the early 2000s, there was no mention of Service 170A until its reappearance in 2014 as an ad-hoc service.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. Only on Sunday, 27 December 2015 was Service 170A formally introduced as a full-day service, operating daily.
Following the introduction of Service 170A, departures of Service 170 (Red Plate) 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 drivers, 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 (Currently, SBS Transit rosters only Malaysian drivers to cross-border services). Departures from Queen Street Terminal are staggered with its parent Service 170 (Red Plate) to space buses apart.
