Choa Chu Kang’s elevated North South Line platform level has two platforms in an island platform arrangement. Half-height Platform screen doors are installed at the platform edge for commuters’ safety, and High Volume, Low Speed (HVLS) fans keep passengers cool. Similar to most platforms along the Eastern side of the East West Line, a barrel vault roof design allows for a spacious interior that is easily navigated.
A set of escalators, stairs and lifts connect to the concourse level below. A new wing at the West end of the station accommodates escalators and stairs that lead directly to the Circle Line concourse.
Passenger Information Systems, which are plasma display screens located at each platform, display expected train arrival times and key messages. Tactile flooring helps to guide the visually-handicapped from the platform to station exits and the Circle Line platforms.
Bukit Panjang LRT (L2):
|Platform 4: Alighting only|
|Platform 1 & 2: (Alternate services)
Service A to Choa Chu Kang via Senja and South View (→)
Service B to Choa Chu Kang via Petir and South View (→)
|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. Fixed, half-height barriers along the platform edge are installed for passenger safety, especially during peak hours when the small platform gets crowded.
Services A and B operate out of Choa Chu Kang station and are staggered one after the other. Both services run till Bukit Panjang, thereafter Service A plies the clockwise route (via Senja), while Service B plies the counter-clockwise route (via Petir), before returning to Bukit Panjang and back to Choa Chu Kang.
Passenger Information Systems, which are LED displays located at each platform, display expected train arrival times and scrolls through messages, while an analog clock gives the time. Tactile flooring helps to guide the visually-handicapped from the platform to the station exits. Staircases and lifts connect both platforms to the mezzanine transfer area and station concourse.
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.
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, a new Exit E provides an alternative exit from mezzanine level, at the side of the BPLRT station.
The concourse feature faregates for automatic fare collection and provides access between paid and unpaid areas of the station, with at least one bidirectional wide-swinging gate for the benefit of passengers-in-wheelchairs and those carrying bulky items or travelling with prams. General Ticketing Machines allow commuters to purchase tickets for single or multiple journeys, and along with a Transitlink Add-Value Machine, offer contactless card transactions. As with other BPLRT stations, Exit E only has one ticketing machine serving both paid and unpaid areas, with a swing gate that allows either side to access the machine at any one time.
At the NSL concourse, the station office functions as a Passenger Service Centre, where commuters may make travel inquiries or perform card transactions using cash payment. Retail shops and public toilets are located in the unpaid area of the NSL concourse.
Choa Chu Kang MRT/LRT station has five exits at ground level (A, B, C, D and E). All exits offer barrier-free accessibility with the exception of Exit E.
