Mumbai Metro
Template:Short description Template:Use Indian English Template:Infobox Public transit
The Mumbai Metro is a rapid transit train system serving the city of Mumbai and the wider Mumbai Metropolitan Region in Maharashtra, India.
While the Maharashtra Metro Rail Corporation Limited is responsible for all metro rail projects being developed in Maharashtra, except for those in the Mumbai Metropolitan Area, the Mumbai Metropolitan Region Development Authority is the authority responsible for maintaining the metro system in the Greater Mumbai area.
The rapid transit metro system is designed to reduce traffic congestion in the city and supplement the overcrowded Mumbai Suburban Railway network. It is being built in three phases, over 15 years, with overall completion expected in October 2026. The Mumbai Metro is the third longest operational metro network in India with an operational length of Template:Cvt as of October 2025. When completed, the core system will comprise sixteen high-capacity metro railway lines, spanning a total of more than Template:Convert (25% underground, the rest elevated, with a minuscule portion built at-grade) and serviced by 350 stations.<ref>Template:Cite web</ref>
Blue Line 1 of the Mumbai Metro is operated by Mumbai Metro One Private Limited (MMOPL), a joint venture between Reliance Infrastructure (74%), Mumbai Metropolitan Region Development Authority, (26%) and formerly by RATP Dev Transdev Asia (5%).<ref name=ratp>Template:Cite web</ref> While lines 2, 4, 5, 6, 7 and their extensions will be built by the Mumbai Metropolitan Region Development Authority (MMRDA) and operated by the Maha Mumbai Metro Operations Corporation Limited (MMMOCL), the completely underground Aqua Line 3 and Green Line 11 will be built by Mumbai Metro Railway Corporation Ltd (MMRC).
In June 2006, Prime Minister Manmohan Singh laid the foundation stone for the first phase of the Mumbai Metro project, although construction work began in February 2008.<ref name="BS">Template:Cite news</ref><ref name="DNA-I2013">Template:Cite news</ref><ref>Template:Cite news</ref> A successful trial run was conducted in May 2013,<ref>Template:Cite news</ref><ref name="VersGhatTrial">Template:Cite news</ref><ref name="TrialRunNDTV2013">Template:Cite news</ref> and the system's first line commenced operations on 8 June 2014. Many metro projects were delayed because of late environmental clearances, land acquisition troubles and protests.
After nearly eight years, two new metro corridors, 2A and 7, were inaugurated on 2 April 2022, and are now operational. On 5 October 2024, the Template:Convert underground BKC to Aarey Jogeshwari-Vikhroli Link Road section of Aqua Line 3 was inaugurated. On 9 October 2025, Aqua Line further extension till Cuffe Parade was inaugurated and now its fully operational. Additionally, there are 8 other metro lines currently under construction in the city.
History
Being the capital of Maharashtra, Mumbai is among the largest cities in the world, with a total metropolitan area population of over 2 crore (20 million) as of 2011,<ref>United Nations Population Division - City Population Template:Webarchive. Retrieved 5 October 2011.</ref> and a population growth rate of around 2% per annum.<ref>Average Annual Rate of Change Template:Webarchive. United Nations Population Division. Retrieved 5 October 2011.</ref> Mumbai has the advantage of a high modal share of the public (88%) in favour of a public mass transport system.<ref>Template:Cite web</ref> The existing Mumbai Suburban Railway carries over 70 lakh (7 million) passengers per day,<ref>Mumbai Suburban Railway Network. Western Railway – Indian Railways. Updated 9 April 2012. Retrieved 26 April 2012.</ref> 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. Until 1980s, transport in Mumbai was not a big problem. The discontinuation of trams resulted in a direct increase of passenger pressure on the suburban railway network. By 2010, the population of Mumbai doubled. 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.<ref name = "mmrda1">Template:Cite web</ref> 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 Template:Convert, and to serve the areas not connected by the existing Suburban Rail network. The master plan unveiled by the MMRDA in 2004 encompassed a total of Template:Convert of track, of which Template:Convert would be underground.<ref name = "economictimes1">Template:Cite news</ref> The Mumbai Metro was proposed to be built in three phases, at an estimated cost of Template:INR19,525 crore.<ref name = "mmrda1"/> In September 2009, the proposed Hutatma Chowk – Ghatkopar was reduced to a line between Hutatma Chowk and Carnac Bunder.
In 2011, the MMRDA unveiled plans for an extended Colaba-Bandra-SEEPZ metro line. According to its earlier plans, a Template:Cvt Colaba-to-Bandra metro line was to be constructed, running underground for Template:Convert 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 Chhatrapati Shivaji Maharaj International Airport. The Template:Convert Colaba-Bandra-SEEPZ line will be built at a cost of Template:INRConvert,<ref name=CSIAtalks>"Development body in talks with CSIA". The Indian Express. 14 January 2012.

Retrieved 30 December 2011.</ref>
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.<ref>Template:Cite news</ref> 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.<ref>"Mumbai Metro likely to get autonomy status: MMRDA".

Retrieved 3 May 2012.</ref> 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 Template:Convert, 28-station Wadala–Kasarvadavali line, received in-principle approval from the state government in 2013.<ref>"Soon, take a metro from south Mumbai to Thane" Template:Webarchive.

The revised Mumbai Metro master plan had proposed a line along the Thane-Teen Haath Naka-Kapurbavadi-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 Template:Cvt line with 29 stations, to be built at an estimated cost of Template:INR22,000 crore.<ref>Template:Cite news</ref> 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.<ref>Template:Cite news</ref>
In May 2015, the MMRDA said 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.<ref>Template:Cite web</ref>
In a report on 14 November 2014 about the cancellation of the PPP agreement for Line 2, Mint quoted a senior MMRDA official: "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."<ref name="livemint.com">Template:Cite web</ref> 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, 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.<ref>Template:Cite web</ref> The Government plans to implement all future metro lines (except Line 3) as elevated corridors.<ref name="hindustantimes.com">Template:Cite web</ref> 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.<ref name="hindustantimes.com"/>
In June 2015, Fadnavis announced that he would request the Delhi Metro Rail Corporation (DMRC) to assist in the implementation of the Mumbai Metro. He said that he intends to expand the metro system by Template:Cvt before the state assembly elections in October 2019.<ref>Template:Cite web</ref><ref>Template:Cite news</ref><ref>Template:Cite web</ref> In July 2015, UPS Madan announced that the State Government formally appointed the DMRC to revise and update the Mumbai Metro master plan.

In 2018, the Mumbai Metro Rail Corporation chose Alstom to supply 31 eight car trains for Aqua line (line 3). These trains are capable of driverless operations and were built at Alstom's factory in Sri City, Andhra Pradesh.<ref>Template:Cite web</ref>
In 2018, Mumbai Metropolitan Region Development Authority which will operate all metro lines except Line 3, awarded a tender to Bharat Earth Movers Ltd. (BEML) to supply 63 trainsets (378 coaches) for Yellow Line (Line 2) and Red Line (Line 7) at a cost of ₹3,015 crores ($427.33 million). Capable of driverless operations, the trains are manufactured at BEML's factory in Bengaluru and the first train set for the Yellow Line arrived in Mumbai on 27 January 2021, and will continue to receive the rest of the sets until 2022.<ref name="beml3015">Template:Cite news</ref><ref name="beml427">Template:Cite news</ref> On 17 January 2021, Bombardier won the tender to supply 234 driverless coaches for the Green Line (Line 4) of six-car configuration for Mumbai metro. However, the contract was cancelled in March 2022 due to delays and uncertainties of the project.<ref>Template:Cite news</ref><ref>Template:Cite news</ref> In August 2025, the MMRDA awarded a contract to L&T to supply 39 trainsets of 6 cars each for the Green Line (Line 4), to be manufactured by Alstom as part of an integrated systems package.<ref>Template:Cite news</ref> In the absence of a depot and delay in procuring rolling stock, the MMRDA also decided to temporarily transport eight idle trains from the Mandale depot on the Yellow Line to the Green Line to commence trials on a section of the line.<ref>Template:Cite news</ref>
In 2025, the MMRDA awarded two contracts to Titagarh Rail Systems for 108 coaches and 132 coaches to be delivered for the Orange Line and Pink Line respectively.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
Power supply
Mumbai Metro runs on alternating current (AC) which is typically more labour and cost-intensive. MMRDA joint project director Dilip Kawathkar stated that AC power was chosen "after a proper study by a team of experts" which found that the AC model was "a better option". Bidders for Line 3 were reportedly in favour of the DC model. Experts believe that the decision to use AC will escalate the project cost of underground lines by 15%, since more digging is required for the rail to work on AC.<ref>Template:Cite web</ref>
Signalling and communications
The Mumbai Metro will feature an advanced signalling system, including an automatic train protection system (ATPS) and automated signalling to control train movements on the Template:Convert Line 1. A four-minute service interval is anticipated on the route.<ref name="Mummetro">Template:Cite web</ref>
Siemens will supply the signalling systems required for the project, while Thales Group will supply the Metro's communication systems. The network's signalling and train control systems will be based on LZB 700M technology.<ref name="Contracts">Template:Cite web</ref>
Ridership and Impact
In October 2025 after the Aqua line became fully operational the avg daily ridership on all Mumbai Metro lines is approximately 900,000 per day, with Blue line at about 460,000, followed by Yellow plus Red at 260,000 and Aqua at 160,000 daily avg ridership. On 21 October 2019, 1,960 days (approx. 5 years) after Mumbai Metro Line 1's inception, the system crossed 600 million passengers, with an average daily ridership of around 450,000 passengers.<ref>Template:Cite news</ref> Opening of subsequent lines has relieved pressure on the Mumbai Suburban Railway, which had become over congested and unsafe due to open doors, unlike the Metro which has closed door air-conditioned coaches.<ref>Template:Cite web</ref> Furthermore, the Metro has been credited for sustainability due to reduced carbon emissions by employing energy saving methods like regenerative braking systems and cutting down traffic congestion, besides eco-friendly construction methods.<ref>Template:Cite web</ref>
Furthermore, the Mumbai Metro has allowed bicycles with special racks for commuters at no extra charge on Red and Yellow lines.<ref>Template:Cite web</ref> However, on Aqua line, they are currently not allowed for crowd rush during peak hours, although officials plan to allow it on completion of the line, while on Blue line, foldable bicycles are allowed.<ref>Template:Cite web</ref>
