The Mass Rapid Transit, or MRT, is a rapid transit system forming the major component of the railway system in Singapore, spanning the entire city-state. The earliest section of the MRT, between Toa Payoh and Yio Chu Kang, opened on 7 November 1987, making it the second-oldest metro system in Southeast Asia, after Philippine’s Manila Light Rail Transit System Line 1 that established in 1984. The network has since grown rapidly in accordance with Singapore’s aim of developing a comprehensive rail network as the backbone of the public transport system in Singapore, with an average daily ridership of 3.031 million in 2015 (including the Light Rail Transit (LRT)), approximately 78% of the bus network’s 3.891 million in the same period.[2]  The MRT network encompasses 178.2 kilometres (110.7 mi) of route, with 106 stations in operation, on standard gauge. The lines are built by the Land Transport Authority, a statutory board of the Government of Singapore, which allocates operating concessions to the profit-based corporations, SMRT Corporation and SBS Transit. These operators also run bus and taxi services, thus facilitating full integration of public transport services. The MRT is complemented by a small number of local LRT networks in Bukit Panjang, Sengkang and Punggol that link MRT stations with HDB public housing estates. – Wikipedia
