Sengkang West Shuttle Bus Services A & B were Rail Replacement Services for the Sengkang LRT (West Loop). Each operated as a one-way service during weekday morning & evening peak hours, respectively.
The services ran from 20 April 2026 to 2 October 2026, in tandem with the full closure of the Sengkang LRT West Inner Loop (19 Apr–3 Oct 2026). During this period, train service on the West Outer Loop (Sengkang → Renjong → Cheng Lim → Sengkang) continued to operate normally.
Originally planned to operate until Friday, 16 October 2026, construction works ended two weeks ahead of schedule. As a result, the last day of service was brought forward to Friday, 2 October 2026.

Background
To help manage the impact of the SKLRT West Inner Loop closure, dedicated shuttle bus services were operated during weekday peak hours to supplement remaining LRT capacity and minimise additional travel time for commuters.
Shuttle Bus Service A operated from 6.00 am to 10.00 am, running one-way from Fernvale → Layar → Tongkang → Renjong → Sengkang, covering the southern half of the West Loop.
Shuttle Bus Service B operated from 5.30 pm to 9.30 pm, running one-way from Sengkang → Cheng Lim → Farmway → Kupang → Thanggam, covering the northern half of the West Loop.
Both services ran at a frequency of 3 to 5 minutes.
To give commuters time to familiarise themselves with the new arrangements before the LRT closure begins, both shuttle services began operations on Monday, 13 April 2026 — a week ahead of the West Inner Loop suspension on 19 April 2026.
Stations Served
This Shuttle Bus Service served the following LRT Stations:
| Shuttle A | Shuttle B |
Shuttle A Special Departures
From mid-April, four additional special departures of Shuttle A operated from Thanggam at 6.45 am, 6.55 am, 7.05 am, and 7.15 am, before continuing to Fernvale and then along the regular Shuttle A route. These departures also make an extra stop along Fernvale Road (Blk 436A), to serve students attending Sengkang Green Primary School.
These special departures were not detailed within LTA’s original announcements, but were arranged following feedback from residents and publicly announced by Member of Parliament (MP) Ng Chee Meng on Facebook on 21 April 2026, who mentioned that he requested the arrangement on behalf of his constituents.
In a subsequent update, MP Ng Chee Meng announced that from Monday, 11 May 2026, all four special morning departures would be extended to start from Kupang instead of Thanggam, with no changes to the Thanggam departure times. The estimated departure times from Kupang are 6.42 am, 6.52 am, 7.02 am, and 7.12 am.
