Branch of the EWL, which connects to the airport from Tanah Merah station as a shuttle service. The official station code is CG2, previously EW29. The next station towards Tanah Merah is Expo station. In 2040, the station will be served by the TEL when the line extends to the airport. When the station first opened on 8 February 2002, the station was served by a through service from Boon Lay station to this station. However, due to low ridership, from 22 July 2003, this service reverted to a shuttle service, with trains from Changi Airport station terminating at Tanah Merah station instead. The first train from Changi Airport station departs at 5:31am on weekdays and Saturdays and 5:59am on Sundays instead, with the last train from the airport departing at 12:06am. From Tanah Merah station, the first train towards the station departs at 5:20am on weekdays and Saturdays and 5:47am on Sundays instead, with the last train towards the airport from Tanah Merah station departing at 11:50pm. Headways between trains varies from 7 to 13 minutes. Design The station is wide and long, and was constructed at a depth of . Designed by architectural firm Skidmore, Owings and Merrill, various features have been incorporated into the station design to enhance the commuting experience of airport travellers. The station has wider faregates for commuters with luggage. These faregates, located on the same level as the station, also allow easier access for wheelchair users into the station. Changi Airport station is one of the first MRT stations to be wheelchair-accessible, with lifts and ramps retrofitted for barrier-free access. A tactile system, consisting of tiles with rounded or elongated raised studs, guides visually impaired commuters through the station. At the two entrances of the station are glass atrium walls supporting an illuminated linkbridge spanning over the island platform. The glass bridge allows unpaid transfer between the two terminals. At either end of the station is an atrium measuring approximately long by high. Australian engineering company Meinhardt Facades provided structural design engineering of the glazing system and the tensioned cable structure of the atria's walls, with engineering input by Ove Arup and Partners. The atria are designed to allow maximum sunlight into the station, with minimal structures used to maintain the transparency of the atria. The roof is only supported at its northern and southern ends, with a massive beam (the spine) running
