History of the MRT System

The construction of the Singapore Mass Rapid Transit (MRT) System was the largest infrastructure project undertaken by the Republic during the early days of independence. The only choices of public transport available in Singapore in the early 60s were buses, taxis and trishaws and the lack of seamless connectivity of the public transport system resulted in long and inconvenient journeys.

"This is going to be the most expensive single project to be undertaken in Singapore. The last thing that we want to do is to squander away our hard-earned reserves and leave behind enormous debt for our children and our grandchildren. Now since we are sure that this is not going to be the case, we'll proceed with the MRT, and the MRT will usher in a new phase in Singapore's development and bring about a better life for all of us."

-- Minister for Communications Ong Teng Cheong, Early 1980s

Studies and Debates 1967-1982

State and City Planning Study

To cope up with Singapore's rapid social and economic growth in the early 1960s, a comprehensive land use and transport plan was needed. Therefore, the government sought the help of the United Nations (UN) to devise a long-term framework for urban development in Singapore. UN representatives visited Singapore in 1962 and 1963 and gave their recommendations to the Planning Department of Singapore. This formulated the launch of the State and City Planning Project in 1967, assessing land use and transportation needs.

The findings of the 4 year study, conducted by the United Nations Development Programme and the Singapore State and City Planning Department, outlined Singapore's first concept plan - a long-term plan to guide the country's physical development for the next 20 years - and forecasted a need for a rail system by 1992.

Mass Transit Study

In 1972, a team of consultants and professional officers seconded from the government conducted the Singapore Mass Transit Study, which carried out in 3 phases from 1972 and 1980.

Under Phase I of the study, the cost and benefits of five alternate mass transit concepts, including an all-bus system, was analysed and the team recommended a rail mass transit as the best option for meeting the anticipated travel demands of Singapore.

Phase II of the study was conducted in 1975 to examine the technical, economic and financial feasibility of the mass transit system. Through the findings of the study, a proposed rail system operating through most densely populated areas was economically and technically feasible. A basic route recommended with two separate lines, one running east-west and the other line running north-south. Despite the recommendation for the development of an MRT system, the possible impact on patterns of land use and economic activities as well as the high costs involved prevented the government from making an immediate decision. It was also complicated by a review of the phase two study by a team from the World Bank, in which issues where brought up with the costing and assessment of the relative benefits of the bus-rail plan compared to an all-bus system.

Phase III of the study, conducted between 1979 and 1980, provided a preliminary engineering design for the recommended MRT system. In this study, the station locations were identified, budget estimates were made and the construction and operational details were established.

Rail vs Bus

The government was hesitant to commit to an MRT system despite the findings of the Mass Transit Studies. Then Minister for Communications, Mr Ong Teng Cheong, favoured a mass rail transit system ever since he was a part of the planning team that proposed it in 1967. Dr Goh Keng Swee, then Finance Minister, opposed an MRT system because of its high cost and preferred a much cheaper all-bus system.

Thereby, a team of foreign consultants led by project director Kenneth Hansen with Professor John Meyer, both from Harvard University, was engaged to review the mass transit and other transportation studies that had been conducted.

In the report, they argued that the earlier studies were based on an incorrect assumption and therefore failed to consider other means to solve Singapore's transport problems. Instead of an MRT system, the team recommended a high performance all-bus system coupled with feeder routes and motorcar restraint. Even if an MRT system is developed, the team suggested that only one line will be built as they believed that it would be sufficient to relieve traffic congestion and allow the bus system to function.

Comprehensive Traffic Study

In 1980, a provisional Mass Rapid Transit Authority was appointed to conduct preparatory work for the construction of a possible MRT system.

A Comprehensive Traffic Study was then conducted in 1981 by the provisional Mass Rapid Transit Authority, and it confirmed that a rail system was crucial to the Republic's anticipated transportation needs. It concluded that an all-bus system would impose severe restrictions on other road users while not providing a comparable service.

MRT System Designs Option Study

An MRT System Designs Option Study was also conducted to refine the technical details and the recommended measures for the MRT system, such as having Platform Screen Doors at underground stations and utilising the third rail for power transmission.

Green Light

In May 1982, the government gave the go-ahead to build and completely finance the proposed $5 billion MRT system with the completion deadline set for 1992.

"The Government has now taken a firm decision to build the MRT. The MRT is much more than a transport investment, and must be viewed in its wider economic perspective. The boost it'll provide to long term investors' confidence, the multiplier effect and how MRT will lead to the enhancement of the intrinsic value of Singapore's real estate are spin-offs that cannot be ignored."

-- Minister for Communications Ong Teng Cheong, May 1982

Proposed Initial System

The proposed initial system was announced during the announcement for the go-ahead to build the MRT system in May 1982. The system consists of 42 stations along two lines - running north to south and east to west - to cover all four corners of the island. The finalised station locations that were built were largely similar to the proposed station locations.

Construction of the MRT 1983-1988

In September 1983, the Provisional MRT Authority awarded the first major tunnelling contract to Japanese contractors Tobishima/Takenaka Komuten and Doboku joint-venture for the construction of tunnels from Toa Payoh station to Newton Circus, as well as Toa Payoh and Novena stations. In the following month, the Mass Rapid Transit Corporation (MRTC) was incorporated before the ground breaking ceremony on 22 October 1983 at Shan Road.

The route of the initial system was finalised with 42 stations at a total length of 67km across the island, with 48km above-ground and 19km through tunnels. There will be two lines running north-south from Yishun to Marina Bay, and east-west from Pasir Ris to Boon Lay. A spur line to Choa Chu Kang will be branched from Jurong East station of the east-west line.

In December 1984, Minister for Communications and Information Dr Yeo Ning Hong announced that the entire system will be opened by 1990, 2 years ahead of schedule. The first tunnel breakthrough was at Outram Park station with a ceremony held on 27 May 1985. Several months later, the first station to be completed and topped out was Toa Payoh station on 5 August 1985.

The first two Kawasaki Heavy Industries C151 (KHI) trains arrived Bishan Depot on 8 July 1986, with a ceremony held to commemorate the occasion. The grey brushed aluminium train cars are designed for comfort and convenience. The train cars are well insulated against sound and heat and have tinted, double-glazed windows; with air-conditioning to cool the interior. A KHI train car can hold 62 seated and 238 standing, and can carry up to 1800 passengers per train during peak hours.

The last viaduct beam on Phase 1/1A was launched on 27 November 1986 and by the early 1987s, all 20 stations from the first phase are structurally completed.

Nine of the underground MRT stations are self-sufficient as part of Singapore's Civil Defence network - all services, including electricity and water supply, climate control, even toilet facilities, are enclosed and protected by special blast doors, filters and sliding walls which can seal the station in an emergency.
The nine Civil Defence Shelter stations are: Braddell, Newton, Somerset, Raffles Place, City Hall, Tiong Bahru, Bugis, Lavender and Marina Bay

Opening of the MRT 1987-1990

Incorporation of Singapore MRT Limited

On 6 August 1987, in line with the government's policy of allowing the private sector to operate in areas where the government's direct participation is not essential, Singapore MRT Limited (SMRT) was incorporated. SMRT will take over the operations and responsibilities of the system from the MRTC. An initial 10-year licence to operate the MRT was granted to SMRT.

Phase 1/1A

On 7 November 1987, the first 5 stations of the North-South Line from Yio Chu Kang to Toa Payoh opened for passenger service. The line was extended from Toa Payoh to Outram Park the following month on 12 December 1987.

Guest of honour Prime Minister Lee Kuan Yew graced the official opening of the MRT system on 12 March 1988 to mark the completion of Phases 1 and 1A of the initial system, from Yio Chu Kang to Clementi. Passenger service from Outram Park to Clementi commenced the following day on 13 March 1988.

By April 1988, ridership on the MRT rose to more than 200,000 passengers per day.

Phase 2

As part of Phase 2B of the initial system, the single-running line of the MRT was extended westwards to Lakeside on 5 November 1988, and northwards to Yishun on 20 December 1988. Phase 2A was completed on 4 November 1989, connecting Raffles Place to Marina Bay, and City Hall to Tanah Merah. This starts the separation of the North-South Line and the East-West Line of the MRT system. A further extension of Phase 2A from Tanah Merah to Pasir Ris opened on 16 December 1989.

As part of Phase 2B, a branch line that extended off Jurong East station commenced service on 10 March 1990, serving commuters between Jurong East and Choa Chu Kang. The last section of Phase 2B between Lakeside and Boon Lay opened on 6 July 1990, marking the completion of the initial system of the MRT comprising 42 stations over a route length of 67km.

"It is worth restating the rationale behind our decision to build the MRT. We have only a limited amount of land on which to house our people, build factories, hospitals, roads and schools, and train the SAF. Therefore, we decided to give top priority to investments in public transport, and to put private transport in second place.

We do not have the land to allow an unlimited growth of private cars. This means that we must put the MRT to optimal use, and the bus services must dovetail and complement the MRT. We must also keep improving the bus and taxi services and keep the growth of cars to moderate levels."
