Commonwealth MRT Station (EW20) is an above-ground MRT station located on the East West Line of the Mass Rapid Transit in Queenstown, Singapore. The station serves the nearby neighbourhoods of Tanglin Halt and Commonwealth and schools such as New Town Primary School and Queensway Secondary School. Its station colour is yellow.

The residential estates and station bearing the same name were named after Commonwealth Avenue built around 1963, in turn named after the British Commonwealth of Nations. Commonwealth station is a transport node for residents in the vicinity of Commonwealth Avenue, serving adjacent schools, places of worship, housing developments and businesses.^[1]

History

On 5 January 1985, Lim Kah Ngam and Aoki had won the MRT contract for the construction of Commonwealth and Buona Vista stations together with the viaduct from Queensway to Clementi Road. This is under Contract 203.^[2] When the MRT network commenced operations in 1987, Commonwealth as with all above-ground stations had no physical barriers between the platforms and tracks. Following numerous incidents of commuters falling on the tracks and unauthorized intrusions, the Land Transport Authority made the decision in 2008 to install half height platform screen doors for all above-ground stations in phases. The screen doors were installed on January 2011 and started operations on 28 April 2011 together with Queenstown.^[3]

The fans began operating since 25 June 2012, together with Buona Vista, after the installation of the MJ Air Tech High Volume, Low Speed (HVLS) Pro-Jet fans completed.
