Mass Rapid Transit (Singapore). The Mass Rapid Transit is a heavy rail metropolitan system that forms the backbone of the railway network in the Republic of Singapore. Operated by SMRT Trains and SBS Transit, the network has evolved into a comprehensive system critical for the city-state's public transport, integrating with an extensive Light Rail Transit network and bus services.

History

The system's conception followed key studies, including the 1972 State and City Planning study and the 1980 feasibility study by the Ministry of Communications and Wilbur Smith Associates. Construction began in 1983 under then Prime Minister Lee Kuan Yew, with the initial section between Yio Chu Kang and Toa Payoh opening in 1987. Major expansions followed, including the North South Line extension to Marina Bay and the launch of the East West Line, Circle Line, and Downtown Line. Significant incidents, such as the 2011 Singapore MRT disruption, led to major operational reviews and the formation of the Land Transport Authority.

Network

The operational network comprises six lines: the North South Line (red), East West Line (green), North East Line (purple), Circle Line (yellow), Downtown Line (blue), and Thomson–East Coast Line (brown). Key interchange stations include Dhoby Ghaut, Raffles Place, and Jurong East, facilitating connectivity across the island. The network interfaces with the Light Rail Transit systems in Sengkang, Punggol, and Bukit Panjang, and is complemented by major bus interchanges.

Operations

Daily service runs from approximately 5:30 am to 1:00 am, with frequencies as high as 90 seconds during peak periods on core lines. SMRT Corporation's subsidiary SMRT Trains operates the North South, East West, Circle, and Thomson–East Coast Lines, while ComfortDelGro's SBS Transit operates the North East and Downtown Lines. The system uses a communications-based train control system for signaling. Safety and security are managed by the Singapore Police Force's Public Transport Security Command.

Infrastructure

The network utilizes a combination of elevated, at-grade, and underground sections, with significant tunnels constructed using tunnel boring machines. Trains are powered by a 1,500 V DC overhead catenary system and run on standard gauge track. Major depots include Bishan Depot, Ulu Pandan Depot, and Changi Depot. Stations are designed for accessibility, featuring half-height platform screen doors and integration with surrounding developments like Marina Bay Sands and Jewel Changi Airport.

Fares and ticketing

Fares are calculated based on distance using the EZ-Link card, a contactless stored-value card, or bank cards with contactless payment capabilities. The system is governed by the Public Transport Council, which reviews fare structures. Concessions are available for seniors, students, and persons with disabilities. Integration with the bus network is seamless under the unified fare system, and single-trip tickets are available for tourists.

Future developments

Several lines are under construction or planning, including the Jurong Region Line, Cross Island Line, and extensions to the Downtown Line and Thomson–East Coast Line. These projects aim to enhance connectivity to developing areas like Tengah and Paya Lebar. The Land Transport Authority's Land Transport Master Plan 2040 outlines long-term goals for a more extensive and resilient network, supporting Singapore's development as outlined in the URA's long-term plan.
