The MRT Sungai Buloh-Kajang Line is the ninth rail transit line and the second fully automated and driverless rail system in the Klang Valley area, Malaysia after the LRT Kelana Jaya Line. It is a part of Greater KL/Klang Valley Integrated Transit System under the Land Public Transport Commission of Malaysia (SPAD). The line is numbered 9 and coloured green on the official transit map.
It is one of three planned rail lines under Klang Valley Mass Rapid Transit Project by MRT Corp. The Phase 1 between Sungai Buloh and Semantan commenced service in 16 December 2016. Phase 2 of the line is slated to begin in July 2017.
Background
The MRT Sungai Buloh-Kajang Line is the first of the three planned Klang Valley Mass Rapid Transit lines to be constructed, with estimated contract value of MYR36 billion.
The line starts from Sungai Buloh which is located to the north-west of Kuala Lumpur, runs through the city centre of Kuala Lumpur, and ends in Kajang, a fast developing town located to the south-east of Kuala Lumpur. The line serves a corridor with an estimated population of 1.2 million people.
Phase One of the MRT Sungai Buloh-Kajang Line from Sungai Buloh to Semantan had become operational at the end of 2016 while Phase Two from Semantan to Kajang will become operational by July 2017, allowing trains to serve the entire line. Part of Phase one, between Sungai Buloh and Semantan, commenced service in December 2016.
Announced in 2006, the line was initially planned as a LRT at 43 km in length, linking the densely populated areas of Damansara in the northwest and Cheras in the southeast, through the central business district of Kuala Lumpur city.The government then decided to extend the alignment at both ends to Sungai Buloh and Kajang respectively, adding 8 km to the line for a total of 51 km. In addition, the line was changed to an MRT system, with higher capacity trains.
The line operated by a subsidiary of Prasarana Malaysia Berhad, Rapid Rail Sdn Bhd.
Alignment
The first MRT Line covers a span of 51 kilometres from Sungai Buloh to the Kajang, passing the Kuala Lumpur city centre where the alignment goes underground. The line will be serving a corridor with 1.2 million residents within the Klang Valley region from north-west to the south-east of Kuala Lumpur. According to MRT Corp, the four-car train sets with the capacity of 1,200 passengers will be in place to serve some 400,000 passengers per day, with a headway of 3.5 minutes.
Amendments after public display
After the MRT project was formally launched on 8 July 2011, the following amendments have been made to the original proposed alignment following the public display exercise between March and May 2011:-
31 stations instead of 35 stations will be built and provisions have been made for 3 more stations
Future station 1 (RRI) located between Kampung Selamat and Kwasa Damansara stations
Future station 2 (Teknologi) located between Kwasa Sentral and Kota Damansara stations
Future station 3 (Bukit Kiara) located between Phileo Damansara and Pusat Bandar Damansara stations
The proposed Section 17 was dropped
The location of the proposed TTDI station was moved around 300m southwards to the former Caltex petrol stations. This was due to complaints from Taman Tun Dr Ismail and Damansara Kim residents.
Bukit Bintang East and West stations have been combined into one, moved and integrated with KL Monorail station. The station was named Bukit Bintang Central Station and subsequently Bukit Bintang Station.
Park and Ride facilities has been increased to 16 from 13 previously.
Taman Mesra station has been removed.
Adjustments to the alignment:
Shifting alignment into the former Rubber Research Institute of Malaysia land in Sungai Buloh to cater for future development
Adjusting the alignment adjacent to Bandar Kajang station to avoid going through the town centre and through Kajang Stadium.
Stations
Sungai Buloh-Kajang Line comprises 31 stations, with 7 stations located along a 9.5 kilometre underground railway system.
The stations announced by MRT Corp on its official website are listed as below in order. All the station names are interim and subject to change.
Rolling stock
The rolling stock is manufactured by Siemens/CSR Nanjing Puzhen with a partnership with SMH Rail Consortium Sdn Bhd.

Chronology
August 2006 – The LRT Kota Damansara-Cheras Line proposal was first made known public by the then deputy Prime Minister, Datuk Seri Najib Tun Razak, under a RM10 billion government allocation for the improvement and expansion of the public transportation network in Klang Valley. It was then reported that the line would stretch "some 30 km" through Kuala Lumpur. The combined cost of the new line and the proposed extensions of two existing LRT Kelana Jaya Line and LRT Ampang Line were estimated at RM7 bn back then.
July 2007 – The Ministry of Transport had approved the alignment of the new line, which would then be tabled to the Cabinet for approval. The Government was then saying the line would be completed by 2012. With an average construction period taking three to four years, work should have started by end-2008 to meet the deadline, although that did not happen.
June 2008 – It was reported that the line would comprise 30 stations and stretch 40 km in length through the densely populated areas of Damansara and Cheras, as well as the central business district of Kuala Lumpur city. Cost estimates for the line were then reported at RM4-5 billion, with the majority of the stations elevated.
September 2008 – It was reported that a distance of 5.9 km stretching from Brickfields to Bukit Bintang will be underground, although the number of such underground stations was not announced. It was during this time that the line was said to be 42 km with 32 stations in total, and is being considered for as a mass rapid transit (MRT) system, taking into consideration the suitability of this system based on a population catchment area 878,000. It was also reported that the detailed design stage for the line would commence in 2Q2009.
December 2008 – The Edge Daily reported that the line was set for completion in 2014. The Transport minister of Malaysia, Datuk Seri Ong Tee Keat, declined comment when probed for further details on the cost and timeline.
May 2009 – The Edge Daily reported that the government would be calling for tenders for the LRT Kelana Jaya Line and LRT Ampang Line extension projects but there was no indication on the implementation of the new Kota Damansara-Cheras Line.
September 2009 – Prasarana group managing director Datuk Idrose Mohamed said that the new line could end up longer than the earlier announced Kota Damansara alignment, although he did not offer any further details. It is believed that the line terminus could stretch out further north from Kota Damansara to Sungai Buloh.
April 2010 – The Edge Daily reported that a proposal to extend the line by 16 km is being studied by the government. The proposal calls for the line to be extended from Kota Damansara to Sungai Buloh (additional 3 km) and from Cheras to Kajang (additional 9 km). An additional line from Damansara Utama to Kelana Jaya (additional 4 km) is also being studied. This will bring the total length of the line to 59 km.
June 2010 – During the tabling of the 10th Malaysia Plan, Prime Minister Najib Tun Razak announced that the government is now considering a RM36 billion Klang Valley MRT proposal from Gamuda Berhad and MMC Corporation Berhad. Although the specific details of the alignment have not been revealed, it is reported to consist of 3 lines, one of which has the same general alignment as that of the Kota Damansara-Cheras line. It is not known if this new MRT plan will replace, or be in addition to the original Kota Damansara-Cheras line proposal. While the MRT plan is generally welcomed, observers of public transportation development and the public have become increasingly frustrated and disillusioned with the lack of any real progress in the development of the Klang Valley mass rail system, resulting from the incessant announcements by the government but without any work done.
December 2010 – Prime Minister Najib Tun Razak announced that the MRT Project had been approved by the cabinet and the construction of the first line from Sungai Buloh to Kajang would begin in July 2011. The government had appointed MMC-Gamuda JV Sdn Bhd as Project Delivery Partner where it would play the role project manager. The whole project would be divided into nine parcels in which will be done on open tender basis. 10 km of the line would be underground and 50 km above ground. MMC-Gamuda would be barred from bidding for any tender except for the tunnelling works (the most expensive portion). The project would introduce 60 km of rail tracks plus 35 new stations.
14 February 2011 – SPAD began a 3-month mandatory public display of the alignment at participating municipals and the operator's Prasarana headquarters to obtain objections, complaints and suggestions from the public.
8 July 2011 – Prime Minister Najib Tun Razak officially launched the project in a ceremony. The alignment was adjusted following the public display with the final alignment having a length of 51 km with 31 stations and 16 Park and Ride facilities.
17 August 2011 – The government announced that a new company under the Finance Ministry had been formed to take control of the project from Prasarana. The new company, MRT Corp, would be the asset owner of the project. The company would officially take over from Pasarana on 1 September 2011. Motivation for creating this company was to ensure timely execution and focused vision on the project.
21 October 2011 – MRT Corp shortlisted 5 companies to carry out underground works. They were MMC Gamuda Joint Venture, Sinohydro Group, Hyundai-Gadang-Chengal Jaya Joint Venture, Taisei Corp, and the China Railway Group Ltd.

30 May 2013 – Tunnel excavation works for the MRT Sungai Buloh-Kajang Line began with the world's first Variable Density Tunnel Boring Machine. Commencement of tunnelling works was launched by Malaysian Prime Minister Najib Razak at the Cochrane Launch Shaft. Subsequently, another seven tunnel boring machines were launched to construct the tunnels for the line.
29 June 2014 - The first two train car bodies arrived in Westport, Port Klang, Selangor. The train will be assembled in the country’s first train assembly plant in Rasa, Hulu Selangor. The purpose built plant for the KVMRT project is solely owned and operated by SMH Rail Sdn Bhd. SMH Rail had a consortium partnership with Siemens AG and Siemens Malaysia. Work to assemble the trains began immediately after the first two train car bodies arrived in Westport. The time taken to assemble one train set is about 30 days.
