Mass Rapid Transit (Singapore)

The **Mass Rapid Transit** system, commonly known as the **MRT**, is a rapid transit system that makes up the railways in Singapore, covering most of the city-state. 

Following two decades of planning, the system began operations in November 1987 with 5 stations spread over  of track. The network has since grown quickly in accordance with Singapore's aim of developing a complex rail network as the core of the country's public transportation system, averaging a daily ridership of 3.384 million in 2019. The MRT is known as one of the best rapid transit system in the world.

It is a rapid transit system which links the different places of Singapore together using a network, or different connections of trains. When a person travels from one place to another, he or she boards a train in a train station and then the train moves until the train reaches the place he or she wants to come out, or alight from. Sometimes he or she has to change trains.

## Overview 
About 3.4 million passengers use the MRT everyday. The plans allow for the long-term replacement of the bus network by rail-based transportation as the main way of public transportation. It called for the expansion of the 67&nbsp;kilometres of track in 1995 to over 360 in the year 2030. It was originally planned to be completed by 2024 but this plan was changed due to the Covid-19 pandemic. It will connect to the North South Line at Woodlands station, Orchard and Marina Bay, to the Circle Line at Thomson, Caldecott and Marina Bay, to the Downtown Line at Stevens and Sungei Bedok, and to the East West and North East lines at Outram Park. The first part, or stage, opened in 2019.

The Thomson-East Coast Line was a result of joining two separate lines, the Thomson Line and the Eastern Region Line, which was announced on 15 August 2014. The Thomson Line consisted of the part from Woodlands North to Marina Bay, while the Eastern Region Line consisted of the rest of the joined line.

A new extension to the line was announced on 25 May 2019. The new extension will connect the line to Singapore Changi Airport, allowing people arriving from the airport to go to the city without changing to another train. The tracks of the East West MRT line that currently go to the airport will also be used by this extension, which means that trains on the line will go all the way to Tanah Merah station, and there will be no more East West line trains using these tracks. This extension is expected to open by/before 2040.

### North East Line Extension
To be opened by 2024, the 2-kilometre extension will run from Punggol through Punggol North including the new Punggol Downtown. The extension is for future residents in Punggol North to have access by train to the city centre as well as other parts of Singapore.

### Downtown Line 
The Downtown Line was built in three stages, with the first opening in 2013, the second in 2015, and the third in 2017. An extension to the third stage, known as Stage 3e, will open in 2025, being 2.2&nbsp;kilometres long and with two more stations. When Hume opens, the line will be 42&nbsp;kilometres long and have 37 stations.

On 25 May 2019, the Land Transport Authority announced another extension to the second stage of the line to a new station, Sungei Kadut MRT station. This extension will open in the mid-2030s.

### Jurong Region Line
First proposed as a LRT line when originally announced in 2001, the Jurong Region Line is now going to be a medium capacity line. The new plan will serve West Coast, Tengah and Choa Chu Kang and Jurong. The line will open in stages from 2026.

### Cross Island Line
The 50-kilometre Cross Island Line will go across the island of Singapore, passing through Tuas, Jurong, Sin Ming, Ang Mo Kio, Hougang, Punggol, Pasir Ris and Changi. The addition of the new line brings commuters with another way for east–west travel to the current East West Line. It will also connect to all the other major lines to serve as a key transfer line, adding to the role currently fulfilled by the orbital Circle Line; the Cross Island Line will also become the first line to have interchange stations with all existing lines as of 2023. (Under construction lines **included**). The first stage will open by 2029, and other stages are expected to open by 2031.

### Brickland and Sungei Kadut MRT stations 
On 25 May 2019, the LTA announced two new stations to be built on the North South line. Brickland station will be built between Bukit Gombak and Choa Chu Kang, while Sungei Kadut will be built between Yew Tee and Kranji. Both stations will open in the mid-2030s. The newest rolling stock, the R151, began operations on 4 June 2023 on the East West Line. With 106 trains ordered, it plans to replace the C151, C651 and the C751B.

### North East Line 
On the North East Line, 25 six-car trainsets of the C751A were built from 1999 to 2002 by Alstom. A further 18 trainsets, the C751C, were built by Alstom and Shanghai Electric and entered operation on 1 October 2015. A new model, the C851E, entered service in 2023, with 6 trainsets.

### Circle Line 
For the fourth MRT line, the Circle Line, 40 three-car trainsets of C830s were built from 2005 to 2008 and began operations in 2009. Together with the C751Cs, the same companies made 24 C830C trainsets which began operations on 26 June 2015.

### Downtown Line 
For the fifth MRT line, the Downtown Line, 73 three car C951s were built by Bombardier Transportation and began operations in 2013. An additional 15 trains and a final 4 trains were ordered, bringing the total number of C951s to 92 trainsets.

### Thomson-East Coast Line 
For the sixth MRT line, the Thomson-East Coast Line, 91 four-car trainsets of CT251 rolling stock are built and were delivered between 2018 and 2021, and it began operations in 2020.

## Fares and ticketing 
Stations are divided into two areas, *paid* and *unpaid*, which allow the rail operators to collect fares by controlling entry only through the fare gates, also known as *access control gates*. These gates, connected to a computer system, are able to read and change electronic tickets that can store data, and can store information such as the initial and destination stations and the duration for each trip. General Ticketing Machines sell tickets for single trips or allow the customer to purchase more value for stored-value tickets. Standard tickets can be used up to 6 times within 30 days from the day of purchase. The machines also allow the customer to buy more credit for stored-value tickets. Such tickets require a minimum amount of stored credit.

As the fare system has been connected together by TransitLink, commuters need to pay only one fare and pass through two fare gates (once on entry, once on exit) for an entire journey, even when transferring between lines operated by different companies. The EZ-Link card was introduced on 13 April 2002 as a replacement to the original TransitLink farecard while its competitor the NETS FlashPay card entered the smart card market on 9 October 2009. The adult EZ-link card is at S$15 while the NETS FlashPay card is at S$13.

## Safety and performance 
Assurance has been given by both operators and authorities, that many actions have been taken in an effort to ensure the safety of passengers, with SBS Transit having to make greater efforts in actively publicising its safety considerations on the driverless North East Line before and after its opening. Safety campaign posters are highly visible in trains and stations, and the operators frequently play safety announcements to passengers and to commuters waiting for trains. Fire safety standards are about the same as the strict guidelines of the US National Fire Protection Association. Platform screen doors are installed at all underground stations,

Safety concerns were raised among the public after several accidents on the system during the 1980s and 1990s, but most problems have been fixed. On 5 August 1993, two trains collided at Clementi MRT Station because of an oil spillage on the track, which resulted in 132 injuries. There were calls for platform screen doors to be installed at above-ground stations after several incidents in which passengers were killed by oncoming trains when they fell onto the railway tracks at above-ground stations. The people in charge initially rejected such proposals as they felt that the functional purposes were not worth the high cost of installation, but changed their minds when the government announced plans to install half-height automatic platform gates in a speech on 25 January 2008, reasoning that worldwide installations of these gates reduced the market price for them.

On 16 December 2011, the MRT network suffered what is likely to be the worst breakdown in its 24-year operating history. 'A power rail problem' made North-South Line trains suddenly lose power and stopped in darkness and without air conditioning for up to an hour accompanied only by light from mobile phones.

On 25 September 2024, a serious train problem happened on Singapore’s East–West Line (EWL). A train derailed near Clementi station while it was going back to Ulu Pandan Depot after passengers had left the train. A broken axle box fell onto the railway tracks. This caused part of the train, called the bogie frame, to come loose. Because of this, about 2.55 kilometres of tracks and trackside equipment were badly damaged. Due to the damage, all train services between Boon Lay and Queenstown were stopped. The disruption lasted for six days, and train services only fully resumed on 1 October. This incident became the longest train service disruption in Singapore's history.

In 2025, between 15 July and 17 September, there were 15 major train disruptions across different MRT lines. These problems caused delays and inconvenience for many commuters. Because of these incidents, MRT reliability between July 2024 and June 2025 fell to its lowest level since 2020. This raised concerns among the public about train safety and service quality. Acting Minister for Transport Jeffrey Siow said that the government and transport operators were looking closely into the causes of the disruptions. He said steps would be taken to improve maintenance, upgrade old equipment, and strengthen reliability so that train services would be safer and more dependable in the future.

## Security 
Security concerns related to crime and terrorism were not the biggest priority of the system's planners at its original creation. However, after the Madrid train bombings in 2004 and the failed plan to bomb the Yishun MRT Station, the operators deployed private, unarmed guards to patrol station platforms and check the belongings of commuters.

Recorded announcements are frequently made to remind passengers to report suspicious activity and not to leave their belongings unattended. Digital closed-circuit cameras (CCTVs) have been upgraded with recording software at all stations and trains operated by SMRT Corporation. Trash bins and mail boxes have been removed from station platforms and concourse levels to station entrances, to remove the risk that bombs will be placed in them. Photography without prior allowance was also banned in all MRT stations since.

On 14 April 2005, the Singapore Police Force announced plans to improve rail security by creating a specialised Police MRT Unit, now known as Public Transport Security Command (Transcom). These armed officers began patrols on the MRT and LRT systems on 15 August 2005, conducting random patrols in pairs in and around rail stations and within trains. They are trained and allowed to use their firearms if they need to, including killing if necessary.

## Rules 
### Priority Seating 
Usually, each MRT carriage has a number of seats designated as 'priority seats' near the train doors for the use of the elderly, pregnant women, parents with babies and those with mobility issues. The use of these seats by those who do not fall into the above categories or do not need seats on the MRT has been a topic of repeated public debate in Singapore.

In 2019, LTA launched the "Can I request a seat?" initiative. Under this initiative, LTA will provide passengers with a non-visible health or disability condition or a short-term or temporary condition (such as being on holiday) with a corresponding lanyard or sticker that reads "Can I sit?" upon request.

### Eating or Drinking 
According to Regulation 14 of the Rapid Transport System Regulations, it is prohibited to consume food or drink on MRT carriages or at MRT stations. Offenders can be fined up to S$500. SMRT has stated that this ban also applies to the consumption of snacks (such as sweets) and drinking plain water. Some commentators have argued that SMRT's strict enforcement of this ban, especially in hot weather or for those with legitimate needs (e.g. consuming food or drinks for medical reasons), is disproportionate and unnecessary.

### Photography 
Photography and videography at all MRT stations requires a permit between 10am and 4pm on weekdays. Any photos or videos taken inside the premises without a permit are requested to be removed.
