What is MRT?

Klang Valley Mass Rapid Transit (KVMRT) is a proposed three-line Mass Rapid Transit system in Klang Valley/ Kuala Lumpur. The project was announced in December 2010 by the Government of Malaysia, and was launched by Prime Minister Datuk Seri Najib Tun Razak on 8 July 2011.

The MRT will be integrated with the LRT, Monorail, KTM Komuter and intra/ inter-city buses and will help alleviate traffic congestion by increasing the number of people using public transport in the city centre. When operational, the system targets to carry 400,000 commuters daily.

The first line of this project is the Sungai Buloh - Kajang Line (SBK Line), which stretches 51km and have 31 stations.

Works on the MRT SBK line has begun in July 2011 and is expected to be completed by 2017.

Why we need MRT?

In 2020, it is estimated that the population in the Klang Valley will grow from the current 6 million to 10 million. This means that if every single trip is on private transport, the roads in Klang Valley will be in gridlock.

An effective public transport system is the only solution to this as it can move people in masses and it has optimal usage of space to carry the same number of people.

Rail-based public transport, such as the MRT, LRT or commuter train, always forms the backbone of a city's public transport system as it can carry large numbers of people and can move people quickly because it is not hindered by road traffic.

Klang Valley currently has a shortage of rail-based public transport coverage compared with most public transport-oriented cities. It has less than 20km per million population. Public transport-oriented cities such as Singapore, Hong Kong and London have more than 40km of rail per million population. With the MRT, it will boost the rail-based public transport coverage in Klang Valley significantly.

What benefits will the MRT provide?

Economic growth
The MRT project will create more than 130,000 employment during its construction period and will generate RM3 – 4 billion per annum worth of the Gross National Income (GNI), generated from construction and operations from 2011 to 2020.

Additionally, RM8-12 billion per year will be generated from the 2.5-3.5 x multiplier impact from the construction. With the increase in productivity from better mobility in total, an average of RM21 billion GNI per year will be generated over the next 10 years.

Boosting development and commercial activity
The MRT will push property value up. The improve connectivity provided by the MRT will result in property value appreciation and an estimated increase of RM 300 million in Gross development value.

The MRT will also spur developments in four new areas:

  • Rubber Research Institute development in Sungai Buloh
  • Warisan Merdeka
  • KL International Financial District
  • Cochrane Development

Furthermore, the MRT will boost commercial activity. With the improved connectivity in Klang Valley, it can bring more customers to city centre business districts and be integrated with commercial activities.

The underground stations will also have good linkages with shopping centres.

What facilities does MRT provide?

The MRT adopts the Universal Access Facilities. This means that the MRT stations will be universally accessible not only for people with disabilities (OKU) but also to the elderly, pregnant women, parents with children in strollers, as well as those with luggage.

The MRT stations and trains are holistically designed to support easy access, ensuring that OKUs can regularly and conveniently access public transportation.

All MRT stations are designed with the following features:

  • Entering the station
    • Step-free (no steps for easy mobility)
    • Covered walkways with tactile guide path to station entrance from station car park, nearest bus/ taxi stand and car drop-off area.
    • Chain and intercom connection with Customer Service Officer to communicate with station staff to unlock the parking bays and assist with parking.
    • Navigating inside the station
    • The following will be equipped in all MRT stations:
      • LCD displays and public announcement system on public information and operational messages.
      • OKU priority disabled-friendly lifts with intercom facilitiest
      • Braille markings on lift control buttons
      • Audible warming messages of escalators
      • Lower handrails to stairs and ramps in public areas
  • On the platform
    • Non slip tactile guide path and warning signs at station platform
    • Perch steels by the lift
    • Priority waiting areas at platform
    • Target gap between platform edge and train of 50mm
  • On the train
    • Wheelchair spaces in train next to doors
    • Dynamic route maps in trains
  • Other services
    • Helplines for passengers requiring assistance at lift lobbies and platforms
    • Induction loop at Customer Service Centre
    • Flashing lights in case of emergency for the hearing impaired

Will there be any Park n Ride facilities?

Out of the 31 stations, 16 stations will be equipped with Park n Ride facilities:

  • Sungai Buloh
  • Kota Damansara
  • Taman Industri Sungai Buloh
  • Taman Tun Dr Ismail
  • Seksyen 16
  • Pusat Bandar Damansara
  • Maluri
  • Taman Bukit Mewah
  • Plaza Phoenix

  • Taman Cuepacs
  • Bandar Tun Hussein Onn
  • Taman Koperasi
  • Saujana Impian
  • Kajang

What is the geology formation in the area?

The alignment of the MRT SBK Line traverses through different geological formations which are Karstic Limestone and Kenny Hills.

Large areas of the eastern Kuala Lumpur are underlain with Karstic Limestone that is riddled with cavities, caves and rock surface under a soft soil cover that is very uneven. In other areas, the Kenny Hills formation comprises granite, weathered sandstones and mudstones

Why tunneling is the best method?

Tunneling is the best method to build the MRT SBK line in the inner city of Kuala Lumpur. The tunnels will not obstruct the further development of surface transportation and will not have any visual impact to the existing city skyline. Tunnelling is also the least restrictive method for future land use.

What is the method used for the tunneling?

A good understanding of geology and experience in tunnelling associated with civil works in different geological formations is vital in constructing the MRT efficiently and safely. It is important to control ground loss that will have minimal impact to the buildings above.

The tunnels of the MRT will be built by Tunnel Boring Machine (TBM). These machines will excavate rocks and soil with special tools fixed on a rotating cutterhead while building permanent walls (concrete segment rings) at the same time. Different types of TBMs will be used to tunnel the MRT SBK Line.

Two types of TBM will be used for the tunnelling:

Slurry Tunnel Boring Machine
The Slurry TBM will be used in Karstic Limestone geology. The Slurry TBM supports the excavated tunnel face by pressurised bentonite slurry that ensures ground stability. The Slurry TBM technology was successfully used in the construction of the Stormwater Management and Road Tunnel (SMART) in Kuala Lumpur.

Earth Pressure Balance (EPB) Tunnel Boring Machine
EPB TBM will be used in Kenny Hills geology. The EPB TBM uses excavated soil paste pressure to support the tunnel face. It also supports excavation face by constantly regulating the amount of material excavated with its screw conveyor and its rate of advance.

What are safety features of the tunneling?

State of the art tunnelling methods will be deployed during the construction of the MRT. The use of modern Slurry and EPB tunnel boring machines (TBMs) will make tunneling in Kuala Lumpur safe. These pressurised face machines make tunnelling possible and in prevention of tunnel face collapse where geology is soft, waterlogged sandy or silty soils, in soft clays and in mixed face conditions where soft soils meet rocks in the same tunnel profile.

How MRT Corp will ensures the quality of the MRT project?

The construction methodologies, requirements and materials for the development of the MRT will conform to internationally-recognised best quality practices, standards and codes.

The MRT Project will conform to the following codes:

Environmental Management Plan (EMP)
Comprehensive mitigation and impact programmes such as Environmental Management Programme (EMP) and Safety, Health & Environment Programme (SHE) are implemented to control impacts such as noise, dust, vibration, hygiene and safety impacts among others during the construction of MRT.

Traffic Management Plan (TMP)
During the construction of the MRT, efficient Traffic Management Plan (TMP) will be deployed to minimize inconvenience and disruption to the public. Well-designed plans managed by traffic experts and based on local authorities' guidelines are in place to protect and guide road users and pedestrians in passing through a MRT construction area safely. There will be temporary traffic diversions to facilitate the construction of the MRT.

Emergency Response Team (ERT)
A dedicated 24-hour Emergency Response Team (ERT) with emergency response capabilities on standby to handle urgent solutions such as:

  • Accident response
  • Vehicle breakdown response
  • Minor road repairs
  • Bust pipes, fallen trees
  • Flash flood, ad-hoc detours and diversions
  • Emergency tools – cutting, towing, cones, blinkers
