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.
