The underground stations constructed under MRT Putrajaya Line Phase 2 enhance connectivity within Kuala Lumpur without the need for elevated train viaducts that would occupy more space in the densely built environment. Following the addition, the MRT Putrajaya Line has nine operational stations—covering the existing Tun Razak Exchange Station which functions as an interchange station for both MRT Putrajaya Line and the previously completed MRT Kajang Line—along the 13.5-kilometre underground stretch out of its entire distance of 57.7 kilometres.
The entrances of the new key points were installed with deep roof overhangs in response to the tropical climate while vertical screens facilitate natural ventilation. Furthermore, there are covered walkways leading to the entrances and lay-bys for public and private vehicles to drop off or pick up passengers.
The transit spaces were designed for accessibility by all, equipped with facilities for the differently-abled such as tactile tiles; access ramps; Braille on lift buttons; and low counters.
Each underground station took on unique design theme. For example, the Sentul Barat Station; Titiwangsa Station; Hospital KL Station; Raja Uda Station; and Ampang Park Station have respective surrounding contexts mirrored within—particularly on the concourse and platform levels—via a selection of colours, materials and forms.
SENTUL BARAT STATION
The use of facing bricks in front-of-house spaces, a complement to its cladding of coral red and oxide red, echoes the rustic elements of the historical Sentul Train Depot located nearby.
An interchange connecting to the LRT Ampang Line, LRT Sri Petaling Line and KL Monorail, its interiors feature baffle ceiling panels paired with contrasting colours of blue and grey to simulate the ripples of the Gombak River.
HOSPITAL KL STATION
The application of clean lines and subtle colours, which are soothing to the eyes, is evident in the station situated across from Kuala Lumpur Hospital (HKL). A pedestrian tunnel, linking the concourse level to its entrance within the public hospital’s compound, was completed with travelators. The site is also within walking distance to Titiwangsa Lake Gardens, Istana Budaya (the national theatre) and National Art Gallery, among other attractions.
RAJA UDA STATION
Located at the suburb of Kampung Baru, the station has three entrances built along the main road of Jalan Raja Muda Abdul Aziz, providing accessibility to landmarks comprising the traditional Malay enclave, National Heart Institute and National Library of Malaysia. Its interior design drew inspiration from the silhouette of traditional Malay houses, reflecting the area’s cultural heritage.
AMPANG PARK STATION
Regarded as the most colourful among the underground stations, the gradation of bold shades serves to identify the various levels of this stacked station, besides portraying the urban vibrancy following its close proximity to a host of embassies. —Construction+ Online
