Expo MRT Station (CG1/DT35) is a Mass Rapid Transit interchange station part of the Changi Airport Branch Line (CAL) of the East West Line and the Downtown Line in Tampines planning area, Singapore. It sports a space age architecture designed by world-renowned architect Sir Norman Foster. The roof is clad in titanium, steel, and glass, and its design enabled the platform to be columns-free, invoking a sense of spaciousness. The station is built to handle fluctuating passenger volumes due to events at the adjacent Singapore Expo, and has the large spaces needed to facilitate smooth traffic flow.
The section of underground track between this station and Changi Airport station is the longest underground track between any two MRT stations in Singapore.
This station is the third station in Singapore that serves both an above ground line (East West Line) and an underground line (Downtown Line) after Paya Lebar and Buona Vista together with Tampines. This station serves as the eastern terminus of the Downtown Line from 21 October 2017 till 2024, where it would be replaced by Sungei Bedok as Stage 3 extension of the line opens.
Originally, the station name is called Somapah. It was renamed to Expo in 1999, and was named after Singapore Expo. Initially, there were two exits of the station.
Train services to Expo station were initially operated as a 2-station shuttle service from Tanah Merah when the station first opened and it was first denoted by code E13 for a short while until the MRT map was revamped in 2001 by former cabinet minister Yeo Cheow Tong (who was then Transport Minister). It was then converted to a through service from Boon Lay Station when the other station on the Changi Extension, Changi Airport, opened. However, to cut costs due to ridership falling below expectations, the service was reverted into shuttle mode on 22 July 2003.
The initial numbering of this station was EW28, until 20 June 2003 when it was changed to CG1. The same numbering is now used for Pioneer Station.
The station has a high passenger traffic whenever there are major events occurring in the Singapore Expo. The recent expansion of Singapore Expo helped increase the passenger traffic in the station. However, traffic is still rather low at certain times of the year when there are not many events held. However, this changed in the 4th quarter of 2011 when a new shopping mall called Changi City Point opened at the south of the station and linked to the station by an underpass, bringing more crowds to the station. A business hotel, Park Avenue Changi, is located next to the station.
As with most of the above-ground stations built in the past along the East West Line, it was built without platform screen doors that prevent commuters from falling onto the train tracks. Installation of the half-height screen doors started on 20 June 2011 as the last station of the East West Line. On 31 August 2011, all of the screen doors have been installed and began operating, marking the completion of the installation of all the Platform Screen Doors along the East West Line.
On 28 November 2011, LTA marked the start of construction of Downtown Line 3 (DTL3) with a groundbreaking ceremony at this station. On 31 May 2017, LTA announced that the station, together with the rest of DTL3, will be opened on 21 October 2017.
To facilitate the construction for the Downtown Line 3 Expo Station and it tunnels, part of Changi South Avenue 1 towards Somapah Road and Changi South Avenue 2, together with short section of Expo Drive will be temporarily closed to traffic from 1 September 2012 to May 2017. The Expo Drive is also reopened at the same time. The original underpass as seen in Changi South Avenue 1 has been converted from the public underpass to paid link underpass for connection to Downtown Line whereas the public link is still available at Expo MRT Station with a barricade that is only locked when train services are not running. The station has increased the number of exits from 2 to 7 due to high traffic footfall of Changi Business Park. 
At the same time, TITAN faregates were being installed at Expo MRT Station on 13 July 2017, replacing second generation ST Electronics faregates.
