Spanning the island south to north, from the Tanjong Pagar Railway Station to the Woodlands Checkpoint, the corridor is the site of Singapore's previous rail link to Malaysia. Its revitalization aims to create a public space that provides a green oasis contrasting with the intensity of urban life. The site encompasses four important activity nodes: Buona Vista, the Bukit Timah Railway Station area, the former Bukit Timah Fire Station, and Kranji. In addition to this, the proposal incorporates the creation of two special interest areas through the adaptive reuse of the former Tanjong Pagar Railway Station and an "urban-green-blue integrated concept" at Choa Chu Kang.
Running from the south to the north coast of the Island of Singapore, the rail corridor previously provided a rail link to neighbouring Malaysia. The opportunity to revitalise the rail corridor into a green public space, and a respite from the intense urban conditions of Singapore itself, is a unique one. The Government of Singapore is highly ambitious and asks for proposals for four crucial nodal points on the Rail Corridor, including a former railway station, fire station, new housing, and other new programs, as well as a masterplan for the entire length of the corridor.
