Expo MRT Station

Address: 1 Expo Drive | SINGAPORE | Singapore
Latitude/Longitude: 1.33547, 103.962

Expo Station is the first Mass Rapid Transport station on the new Changi Airport MRT Extension that visitors will encounter after leaving the airport. It serves the new Singapore Expo Complex and is an exciting modern gateway to Singapore. With as many as 17,000 passengers using the station during peak periods the key design creteria were clarity of movement and durability of materials.


The station has elevated platforms, accessible by lift or escalators from the concourse level. Along section, cut from the floor dividing the platform and concourse, allows passengers glimpses of the trains passing overhead as they enter the station, thus aiding orientation. At the ground level the concourse has open grilles on the street side and a lush tropical garden between the station and the Singapore Expo Complex on the other side, allowing the free flow of air through the building. The platforms and surrounding paving are surfaced in hard wearing grey granite.

The titanium roofs

Two dramatic roof structures surmount the station – a 38-metre-diameter stainless-steel disc covers the ticket hall and 200-metre-long titanium-clad torus shelters the platform and the concourse below. The shapes overlap, crating a dynamic visual effect. The platform roof structure is technically very efficient – consisting of a ‘diagrid’ of steel members, it is so stable that only two pairs of V-shaped columns are required to support its length.

The highly reflective roof materials serve a variety of purposes. The exterior titanium cladding has a 100-year warranty and will require little cleaning or maintenance. The mirrored stainless-steel ceiling is animated with the reflections of passengers and train movements. It also scoops daylight onto the platform, minimising the need for artificial lighting. At night, the reflected lights from passing traffic are dynamically distorted around the underside of the stainless-steel disc, creating a colourful play of light. In a country with one of the world’s warmest climates the roof offers an important environmental benefit – the titanium panels reflect the sun’s rays away from the building providing an atmosphere on the platform that is three or four degrees lower than the temperature outside the station.
