Platforms

North South Line (L2):

Platform A: North South Line towards NS1EW24 Jurong East via NS3 Bukit Gombak (→) Platform B: North South Line towards NS28 Marina South Pier via NS5 Yew Tee  (←)

Choa Chu Kang’s elevated North South Line platform level has two platforms in an island platform arrangement.

As part of the Jurong Region Line works, an additional island platform will be built next to NSL Platform B (Southbound / towards Marina South Pier) to facilitate cross-platform transfers to the Jurong Region Line.

Bukit Panjang LRT (L2):

Platform 4: Alighting only

Platform 1 & 2: Service A towards BP1NS4 Choa Chu Kang via BP2 South View and BP13 Senja (→) Service B towards BP1NS4 Choa Chu Kang via BP2 South View and BP7 Petir (→)

Platform 3: Alighting only

The Bukit Panjang LRT station is overground with one island platform for passenger boarding, and two side platforms for passenger alighting.

Services A and B operate out of Choa Chu Kang station. Both services run till BP6 Bukit Panjang, thereafter Service A plies the clockwise route (via BP13 Senja), while Service B plies the counter-clockwise route (via BP7 Petir), before returning to Bukit Panjang and back to Choa Chu Kang.

Upgrades in 2016

Two new side platforms were constructed at Choa Chu Kang LRT station. The new Platforms 3 and 4 are used for alighting only, thereby freeing up the existing island platform (Platforms 1 and 2) solely for boarding activities. The segregation of boarding and alighting passengers speeds up the movement of commuters, which is very useful for a interchange station like Choa Chu Kang with heavy passenger movement. This arrangement is also known as the Spanish Solution.

The new platforms are not equipped with lifts, hence passengers in need of lifts have to alight at Platforms 1 and 2 for lift access. These new platforms were opened on 27th December 2016.

Concourse

Both the North South Line and Bukit Panjang LRT stations have a common concourse at ground level. The main ticket concourse is located underneath the North-South Line platforms, with stairs leading to a mezzanine level for passengers transferring between both lines. In addition, new Exit E provides an alternative exit from mezzanine level, at the side of the BPLRT station.

Choa Chu Kang JRL station has three above ground Jurong Region Line platforms in a double island platform arrangement, expected to open for passenger service in Year 2027.

The opening was announced to be delayed by about one year in a Written Reply by Minister for Transport Ong Ye Kung to Parliamentary Question on Prioritising Early Completion of Jurong Region MRT Line on 1 Feb 2021, with COVID-19 cited as a reason.

The station platforms are built to four-car length to cater for future expansion, although trains will only operate in a three-car formation.
