Changi Airport MRT station is an underground Mass Rapid Transit (MRT) station in Changi, Singapore. The station is the terminus of the Changi Airport branch of the East-West Line (EWL); it is operated by SMRT Trains and is built in an east-west orientation. The station directly connects to Terminals 2 and 3 of Changi Airport and serves other airport amenities including the retail complex of Jewel. A rail connection to the airport had been planned in the 1980s but these plans were shelved due to the low financial viability of such a branch. With increased air traffic to Changi Airport and the proposed construction of Terminal 3 in 1994, the plans were revived. The current two-station branch line was finalised in 1996 and construction began in 1998. Changi Airport station opened on 8 February 2002 with lower passenger demand than expected, but it continues to provide an alternative transport option to the airport. In May 2019, it was announced Changi Airport station would be incorporated into the Thomson-East Coast Line by 2040 as it extends to the airport's Terminal 5. Designed by Skidmore, Owings and Merrill, Changi Airport station includes elements that cater to airport travellers such as wider faregates at the platforms. The glass atrium walls at the ends of the station support an illuminated bridge that spans the island platform while allowing maximum sunlight into the station.
