Mumbai Metro is a rapid transit system serving the city of Mumbai, Maharashtra. The system is designed to reduce traffic congestion in the city, and supplement the overcrowded Mumbai Suburban Railway network. It will be built in three phases over a 15-year period, with overall completion expected in 2021. When complete, the core system will comprise three high-capacity metro railway lines, spanning a total of . Line 1 of the Mumbai Metro is operated by Mumbai Metro One Pvt Ltd (MOOPL), a joint venture company formed by RATP Développement, Transdev and Reliance Infrastructure, under a 35-year contract.〔 〕 MOOPL operates under the control of Mumbai Metro One Private Limited (MMOPL), formed by Reliance and the Mumbai Metropolitan Region Development Authority (MMRDA).〔 In June 2006, then-Prime Minister of India Manmohan Singh laid the foundation stone for the first phase of the Mumbai Metro project. Construction work began in February 2008.〔 A successful trial run was conducted in May 2013, and the system's first line entered operation on 8 June 2014, though some aspects of the project were afflicted by delays and cost issues. ==History== Mumbai is capital of Maharashtra, the most economically developed state of India. It is among the largest cities in the world, with a total metropolitan area population of over 20 million as of 2011,〔(United Nations Population Division - City Population ). Retrieved 5 October 2011.〕 and a population growth rate of around 2% per annum.〔(Average Annual Rate of Change ). United Nations Population Division. Retrieved 5 October 2011.〕 Mumbai has the advantage of a high modal share of the public (88%) in favour of a public mass transport system. The existing Mumbai Suburban Railway carries over 7 million passengers per day,〔(Mumbai Suburban Railway Network ). Western Railway – Indian Railways. Updated 9 April 2012. Retrieved 26 April 2012.〕 and is supplemented by the Brihanmumbai Electric Supply and Transport (BEST) bus system, which provides feeder services to station-going passengers to allow them to complete their journeys. However, due to the city's geographical constraints and rapid population growth, road and rail infrastructure development has not been able to keep pace with growing demand over the last 4-5 decades. Moreover, the Mumbai Suburban Railway, though extensive, is not built to rapid transit specifications. The main objective of the Mumbai Metro is to provide mass rapid transit services to people within an approach distance of between 1 and 2 kilometres, and to serve the areas not connected by the existing Suburban Rail network. The Government of Maharashtra through the MMRDA, in order to improve the traffic and transportation scenario in Mumbai and to cater to the future travel needs in the next 2-3 decades began exploring the viability of various alternative mass transit systems which are efficient, economically viable and environment friendly. In this context, a detailed feasibility study was carried out under Indo-German technical co-operation by entrusting the consultancy work to TEWET in association with DE-Consult and TCS, during 1997–2000. The study recommended a mass transit corridor from Andheri to Ghatkopar as potentially bankable and economically viable, after examining a number of alternative corridors and alignments. This study was updated by MMRDA in May 2004. Meanwhile, the Delhi Metro Rail Corporation (DMRC) prepared the master plan for Mumbai metro, wherein they recommended extending the Andheri-Ghatkopar section to Versova as part of the master plan and identified it as a priority corridor for implementation. The State Government declared the project as a "public vital infrastructure project" and designated the MMRDA as the Project Implementation Agency (PIA).〔 The master plan unveiled by the MMRDA in 2004 encompassed a total of of track, of which would be underground. The Mumbai Metro was proposed to be built in three phases, at an estimated cost of 19,525 crore.〔 In September 2009, the proposed Hutatma Chowk – Ghatkopar was reduced to a line between Hutatma Chowk and Carnac Bunder.〔http://www.dnaindia.com/mumbai/report-will-lay-foundation-stone-for-metro-4-this-year-cm-devendra-fadnavis-2075908〕 In 2010, the MMRDA revised the estimated cost of constructing the nine lines to .〔 In November 2010, it was decided to extend the Ghatkopar-Mulund route to Teen Haath Naka in Thane.〔 In 2011, the MMRDA unveiled plans for an extended Colaba-Bandra-SEEPZ metro line. According to its earlier plans, a 20-km Colaba-to-Bandra metro line was to be constructed, running underground for from Colaba to Mahalaxmi, and then on an elevated track from Mahalaxmi to Bandra. However, the MMRDA decided to increase ridership on the line by running it out past Bandra to Chatrapati Shivaji International Airport. The Colaba-Bandra-SEEPZ line will be built at a cost of ,〔("Development body in talks with CSIA" ). ''The Indian Express''. 14 January 2012. Retrieved 16 January 2012.〕 and will be the city's first underground metro line. It will have 27 stations.〔("Views on Colaba-Seepz underground metro sought" ). DNA India. 14 December 2011. Retrieved 30 December 2011.〕 On 27 February 2012, the Union Government gave in-principle approval to the plan for Line 3. Money for the project is being borrowed from Japanese International Cooperation Agency (50%), the state government (16%), the central government (14%), and others. In April 2012, the MMRDA announced plans to grant the Mumbai Metro Rail Company increased management autonomy, in an effort to enhance the project's operational efficiency.〔("Mumbai Metro likely to get autonomy status: MMRDA" ). DNA India. 27 April 2012. Retrieved 3 May 2012.〕 In July 2012, the MMRDA announced plans to add more metro lines to its existing plan, including a line parallel to the Western Express Highway from Bandra to Dahisar. This line is expected to reduce the passenger load on the Western Line and vehicle traffic on the highway. Another proposed route, the , 28-station Wadala–Kasarvadvali line, received in-principle approval from the state government in 2013.〔("Soon, take a metro from south Mumbai to Thane" ). ''Hindustan Times''. 23 April 2013. Retrieved 5 June 2013.〕 The MMRDA also intends to convert the proposed Lokhandwala–SEEPZ–Kanjurmarg monorail route into a metro line.〔("MMRDA to add more lines to Mumbai Metro railway project" ). DNA India. 8 July 2012. Retrieved 27 July 2012.〕 The Mumbai Metro master plan was revised by the MMRDA in 2012, increasing the total length of the proposed network to 160.90 km.〔http://www.thehindubusinessline.com/industry-and-economy/logistics/mumbai-metro3-launched-today/article6353788.ece〕 In June 2015, two new lines were proposed. A line from Andheri West to Dahisar West, and a line from BKC to Mankhurd.〔http://indianexpress.com/article/cities/mumbai/over-130-km-of-metro-lines-to-criss-cross-city-by-2020/99/〕 The following table shows the updated master plan unveiled by the MMRDA: On 18 February 2013, the MMRDA signed a memorandum of understanding with Transport for London, the transit authority in Greater London. The arrangement will facilitate the exchange of information, personnel and technology in the transportation sector.〔("Mumbai transport body, London counterpart ink MoU" ).

''Deccan Herald''. 18 February 2013. Retrieved 5 June 2013.〕 The revised Mumbai Metro master plan had proposed a line along the Thane-Teen Haath Naka-Kaapurbavdi-Ghodbunder Road route. The feasibility report concluded that the line was not feasible as most residents of Thane and its neighbouring areas travelled to Mumbai for work daily. On 14 June 2014, Chavan announced that the MMRDA was instead examining a proposal for a metro line along the new proposed route of Wadala-Ghatkopar-Teen Haat Naka route. RITES will prepare the detailed project report and is expected to submit it by August 2014. The preliminary report proposed a 32 km line with 29 stations, to be built at an estimated cost of 22,000 crore.〔http://economictimes.indiatimes.com/industry/transportation/railways/mumbai-metro-services-to-be-extended-till-thane-prithviraj-chavan/articleshow/36547492.cms〕 This would be the fourth line of the metro, after the previously proposed Charkop-Dahisar route was merged with the Charkop-Bandra-Mankhurd route to form Line 2.〔http://timesofindia.indiatimes.com/City/Mumbai/First-Metro-line-to-be-extended-to-Wadala-and-Thane/articleshow/36565838.cms〕 Following the opening of Line 1, MMRDA metropolitan commissioner UPS Madan stated that the authority would focus on constructing the Colaba-Bandra-SEEPZ, Dahisar-Bandra-Mankhurd, and Wadala-Thane-Kasarvadavali lines. He also stated that the other proposed lines had not been cancelled and that they may be implemented in the future.〔 In May 2015, the MMRDA stated that it had begun planning for the Andheri-Dahisar line and Seepz-Kanjurmarg. Both lines are expected to be elevated, although the latter could be constructed underground if a proposal to extend Line 3 to Kanjurmarg is undertaken. DPRs for both lines had been prepared in 2004, along with the master plan, and the MMRDA would now update the DPRs. The agency also intends to construct Line 9 of the metro as an underground corridor from Sewri to Worli. However, planning for the project will only begun after the construction of the proposed Mumbai Trans Harbour Link commences.〔http://www.hindustantimes.com/mumbai/mmrda-plans-two-new-metro-lines-for-mumbai/article1-1349401.aspx〕 In a report on 14 November 2014 about the cancellation of the PPP agreement for Line 2, ''Mint'' quoted a senior MMRDA official as stating, "as decided earlier, all future lines of Mumbai Metro will be constructed by the Mumbai Metro Railway Corp. Ltd (MMRCL), a joint venture between the state government and the Union government."〔http://www.livemint.com/Companies/bKzM6yXoPKaxW1YelH9FBL/Reliance-Infra-pulls-out-of-Mumbai-Metro-Line-2.html〕 On 20 May 2015, Chief Minister Devendra Fadnavis requested officials to consider constructing the Charkop-Bandra-Dahisar and the Wadala-Thane-Kasarvadavali lines as elevated corridors. Although, both corridors had been planned as elevated lines in the Mumbai Metro master plan, the previous Congress-NCP had decided to construct all metro lines underground, after delays and difficulties caused by acquiring land for Line 1. However, Chief Minister Fadnavis believes that the two proposed lines can be constructed quicker and cheaper if they were elevated due to the proposed route of the alignment.〔http://indianexpress.com/article/cities/mumbai/mumbai-metro-rail-state-considers-elevated-metro-route/〕 The Government plans to implement all future metro lines (except Line 3) as elevated corridors.〔http://www.hindustantimes.com/mumbai/metro-2-to-be-built-in-three-phases-2-other-routes-also-on-cards/article1-1359054.aspx〕 On 15 June 2015, the MMRDA announced that it would implement Line 2 of the metro in three parts. The Andheri-Dahisar line will have connectivity with the existing Line 1 and the proposed JVLR-Kanjurmarg line.〔http://www.hindustantimes.com/mumbai/metro-2-to-be-built-in-three-phases-2-other-routes-also-on-cards/article1-1359054.aspx〕 In June 2015, Fadnavis announced that he would request the DMRC to assist in the implementation of the Mumbai Metro. He stated that he intends to expand the metro system by 109 km before the state assembly elections in October 2019.〔http://www.financialexpress.com/article/economy/devendra-fadnavis-plans-to-ask-dmrc-team-to-assist-in-metro-expansion/82971/〕〔http://www.business-standard.com/article/economy-policy/mumbai-metro-seeks-delhi-counterpart-s-help-to-expedite-project-115061500504_1.html〕〔http://indianexpress.com/article/business/business-others/pan-mumbai-metro-network-by-2019-targets-maharashtra/〕 In July 2015, UPS Madan announced that the State Government formally appointed the DMRC to revise and update the Mumbai Metro master plan. The DMRC will prepare DPRs for the Andheri East to Dahisar East, Jogeshwari to Kanjurmarg, Andheri West to Dahisar West and Bandra Kurla Complex to Mankhurd lines.〔http://www.dnaindia.com/mumbai/report-mumbai-metro-master-plan-maharashtra-government-nod-for-delhi-body-revise-and-update-blueprint-2100949〕 The Andheri-Dahisar line will have connectivity with the existing Line 1 and the proposed JVLR-Kanjurmarg line.〔http://www.hindustantimes.com/mumbai/metro-2-to-be-built-in-three-phases-2-other-routes-also-on-cards/article1-1359054.aspx〕 All four lines are proposed to be elevated and constructed as cash contracts.
