The
Mass Rapid Transit Corporation (MRTC) first oulined plans for the Woodlands MRT line in March 1988, which was envisioned to connect
Yishun and
Choa Chu Kang stations via
Woodlands. Initially not part of the first four stations announced for the extension, the station was later included on 19 November 1992 to serve future housing estates in the area and the
Singapore Turf Club, which was to be relocated near the station to free up land at its original site in Bukit Timah. Prior to the construction, eight plots of land owned by the
Jurong Town Corporation were acquired by the government in September 1991 to construct the segment between
Yew Tee and Kranji. In July 1992, part of a hill along Woodlands Avenue 3 had to be removed using explosives to make way for a viaduct connecting between
Marsiling and Kranji. The removal of the hill slope took six months and cost . The contract for the construction of Kranji station, along with the adjacent Yew Tee station, of track and two substations, was awarded to a joint venture between Penta Ocean Construction and Hexagon Construction Pte Ltd at in December 1992. In May 1993, then-Communications Minister
Mah Bow Tan made his first visit to the station site, along with the Marsiling and
Sembawang stations. Mah revisited the site on 28 April 1995 along with the Mass Rapid Transit Corporation (MRTC) chairman Wesley D'aranjo and Minister of State for Communications Goh Chee Wee. The station opened on 10 February 1996 along with the other stations on the Woodlands Extension. Kranji station was the last station to have
half-height platform screen doors installed on 14 March 2012 as part of the
Land Transport Authority's (LTA) programme to improve safety in MRT stations. Between 2012 and 2013,
high-volume low-speed fans were installed at this station as part of a network-wide programme to improve ventilation at the platforms of elevated stations. As part of efforts to improve the overall accessibility of public transport, the overhead pedestrian bridge near Kranji and other stations have lifts installed to improve barrier-free accessibility to major transport nodes. The lifts were installed progressively in 2013. During the evening peak of 3 June 2024, train services on the NSL from Choa Chu Kang to Woodlands were disrupted as a lightning strike damaged a power control box near the station, causing a power trip. A small fire had ignited in the control box, but extinguished by itself when the
Singapore Civil Defence Force arrived. The damaged box had since been replaced. ==Station details==
