Built in 1903 and operated till 2011, the old Keretapi Tanah Melayu (KTM) railway used to run from Tanjong Pagar to Johor. The railway line underwent several changes and was realigned in 1932. The last train departed from Singapore on 30 June 2011 and since then, the land once occupied by the KTM railway has been transformed into the Rail Corridor, a seamless green belt that provides a respite for people.

Restoring nature into the urban fabric and bringing greenery closer to Singaporeans are part of our efforts to transform Singapore into a City in Nature. Today, visitors to the Rail Corridor can walk, run, and cycle along the largely uninterrupted 24km-long Rail Corridor. It is a rustic recreational space for visitors from all walks of life to experience nature and heritage. Iconic landmarks from the old railway along Rail Corridor include the Bukit Timah Railway Station, Railway Staff Quarters, and the two truss bridges that span across Bukit Timah Road and Upper Bukit Timah Road.

The Rail Corridor also serves as refugia and an ecological corridor for biodiversity between key native habitats such as the Bukit Timah Nature Reserve and Southern Ridges. The landscape along Rail Corridor has been carefully curated to reintroduce native plant species to conserve our natural heritage, as well as to provide food sources for our native wildlife. Some notable plant species you can spot along the Rail Corridor include Singapore Kopsia (Kopsia singapurensis), Common Yellow-Stem Fig (Ficus fistulosa), Common Tree-Vine (Leea indica), Bat's Laurel (Prunus polystachya) and Common Sterculia (Sterculia parviflora).
