The station was opened on 10 March 1990 as part of the Branch line,[2] and was given the station number B1. When the Woodlands Extension opened in 1996, the station number was changed to N23, and continued to use it until it adopted its current station number NS2 in 2001.[3]
Installation of half-height screen doors at the station started on 29 June 2010 and commenced on 31 August 2010 as part of the Land Transport Authority's (LTA) programme to improve safety in MRT stations.[4][5][6] In 2012, high-volume low-speed fans were installed at this station to improve ventilation at the elevated station's platforms.[7]
