Metro map of Singapore

The Mass Rapid Transit or MRT is a rapid transit system that forms the backbone of the railway system in Singapore, spanning the entire city-state. The initial section of the MRT, between Yio Chu Kang Station and Toa Payoh Station, opened in 1987 establishing itself as the second-oldest metro system in Southeast Asia, after Manila's LRT System. The network has since grown rapidly as a result of Singapore's aim of developing a comprehensive rail network as the main backbone of the public transport system in Singapore with an average daily ridership of 1.952 million in 2009, just over 63% of the bus network's 3.085 million in the same period.
