The Mumbai Metro is a rapid transit system serving the city of Mumbai, Maharashtra, and the wider metropolitan region. The system is designed to reduce traffic congestion in the city, and supplement the overcrowded Mumbai Suburban Railway (colloquially called local trains) network. It is being built in three phases over a 15-year period, with overall completion expected in 2025. When completed, the core system will comprise eight high-capacity metro railway lines, spanning a total of 235 kilometres (146 mi) (24% underground, the rest elevated, with a minuscule portion built at-grade), and serviced by 200 stations.

As of August 2018, Mumbai metro consisted of 1 operational line (Line 1 - elevated metro from Versova to Ghatkopar), and 4 lines under various stages of construction.[4][5]

Line 1 of the Mumbai Metro system is operated by Metro One Operation Private Limited (MOOPL), a joint venture company formed between RATP Dev Transdev Asia (a 50:50 RATP Développement and Transdev joint venture) (70%) and Reliance Infrastructure (30%).[6] While lines 2, 4, 6, 7 (under construction), 5 and their extensions (bidding in progress) will be built by MMRDA, the completely underground line 3 (also under construction) will be built by Mumbai Metro Railway Corporation Limited (MMRCL). The total financial outlay for the expansion of the metro system beyond the currently operational Line 1 is 821.72 billion (equivalent to 860 billion, US$12.46 billion or €11.12 billion in 2018), to be funded through a mix of equity and bilateral, multilateral as well as syndicated debt.[7]

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.[8][9][10] A successful trial run was conducted in May 2013,[11][12][13] and the system's first line entered into operation on 8 June 2014. Many metro projects were being delayed because of late environmental clearances and land acquisition troubles. The earlier plan promised to public was to go live with about 83 km of metro but only 11km was constructed by 2015. The proposed 15 km line would link Kalyan and Shil Phata with 13 stations, bringing metro connectivity to Kalyan East, Dombivli, Ambernath and Diva.The Metro line-2 will run from Coloba to Bandra from 2023.


Mumbai is the capital of Maharashtra.It is among the largest cities in the world, with a total metropolitan area population of over 20 million as of 2011,[14] and a population growth rate of around 2% per annum.[15] Mumbai has the advantage of a high modal share of the public (88%) in favour of a public mass transport system.[citation needed] The existing Mumbai Suburban Railway carries over 7 million passengers per day,[16] 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.[17] 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 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. Meanwhilation[clarification needed] (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).[17] The master plan unveiled by the MMRDA in 2004 encompassed a total of 146.5 kilometres (91.0 mi) of track, of which 32 kilometres (20 mi) would be underground.[18] The Mumbai Metro was proposed to be built in three phases, at an estimated cost of 19,525 crore.[17] 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 20-km Colaba-to-Bandra metro line was to be constructed, running underground for 10 kilometres (6.2 mi) 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 33.5-kilometre (20.8 mi) Colaba-Bandra-SEEPZ line will be built at a cost of 21,000 crore (US$3.0 billion),[19] and will be the city's first underground metro line. It will have 27 stations.[20]

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.[21] 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.[22] 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 30-kilometre (19 mi), 28-station Wadala–Kasarvadvali line, received in-principle approval from the state government in 2013.[23] The MMRDA also intends to convert the proposed Lokhandwala–SEEPZ–Kanjurmarg monorail route into a metro line.[24]

A metro station under construction in Andheri in March 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.[25] In June 2015, two new lines were proposed. A line from Andheri West to Dahisar West, and a line from BKC to Mankhurd.[26] 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.[28][29][30][31]

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.[32] 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.[33]

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.[34] 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.[35]

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."[36] 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.[37] The Government plans to implement all future metro lines (except Line 3) as elevated corridors.[38] 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.[38]

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.[39][40][41] 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.[42] The Andheri-Dahisar line will have connectivity with the existing Line 1 and the proposed JVLR-Kanjurmarg line.[38] All four lines are proposed to be elevated and constructed as cash contracts. The lines are estimated to cost a total of 21,000 crore (US$3.0 billion), or about 350 crore (US$51 million) per km.[26] In addition, the planned Line 3 and Wadala-Ghatkopar-Thane-Kasarvadavli line of the metro would also be constructed.[42]

Fadnavis announced on 8 April 2017 that the government was considering a circular metro loop line along the Kalyan-Dombivli-Taloja route. The proposed 15 km line would link Kalyan and Shil Phata with 13 stations, bring metro connectivity to Kalyan East, Dombivli, Ambernath and Diva.[43][44]

The line 4 of Mumbai Metro is envisaged to be a 32.32 km (20.08 mi)[60] long elevated corridor, covering 32[60] stations from Kasarvadavali (near Thane) in the north to Wadala in the south. It is estimated to cost 145.49 billion (equivalent to 150 billion or US$2.21 billion in 2018). This project will help connect the city of Thane with Mumbai with an alternate mode of public transport.

The line was approved by the Maharashtra government on 27 September 2016,[61][61][62] and construction work on this line began in mid 2018.[54]

The construction of viaducts and stations is being executed by consortium of Reliance-Astaldi JV and Tata Projects-CHEC JV.

The Asian Infrastructure Investment Bank has extended a multilateral loan of 39.16 billion (equivalent to 41 billion or US$593.93 million in 2018)[63] for this project, and is expected to be completed by 2021-2022.[64]

This corridor is 16.475 km (10.237 mi)[70] long, and runs from Dahisar (East) in the north to Andheri (East) in the south, with a further extension till Bhayander[71] in the north, and Mumbai International Airport Terminal 2[72] in the south. The line is partially elevated (under construction, with completion slated for 2019), and partially underground (approved, with construction planned to begin in 2018).

The elevated section is expected to cost 62.08 billion (equivalent to 67 billion or US$964.99 million in 2018), while the outlay for the recently approved underground section is 6 billion (equivalent to 6.3 billion or US$91.00 million in 2018). Civil works, including viaduct and station works, is being executed by NCC, Simplex Infrastructure and J.Kumar Infraprojects.

The corridor is being funded through multilateral debt to the tune of 22.46 billion (equivalent to 24 billion or US$340.64 million in 2018)[63] by Asian Development Bank. The cost of the 13.5 km extension till Bhayander in the north is expected to be around 36 billion (equivalent to 38 billion or US$546.00 million in 2018).[71][73]

Expected Cost- 6,208 crore

Expected Daily Ridership- 6.7 Lakh

Line 8Edit

This is a proposed metro line extending the planned Line 4 from Wadala in the north to Mumbai GPO in the south.[74] • It will travel from Wadala (Metro Line 4) to GPO (connecting Metro Line3) • Metro-8 corridor will be of 8-km.

Expected Cost- 2,400 crore

Expected Daily Ridership- 3 Lakh[75]

Line 9Edit

Metro line 9 will ply between Dahisar-Mira Bhayander route. It will have 10 stations all elevated. The proposed Metro of Dahisar to Mira-Bhayandar will cut down approximately 30 km of travel distance between the Mira-Bhayandar and Mumbai suburbs. It will be completed by 2022-23.

Expected Daily Ridership – 4.4 Lakh

Line 10Edit

In February 2017, the MMRDA announced that the DMRC was preparing a detailed project report (DPR) on Metro 10, a proposed 9 km elevated extension of Metro 7 from Dahisar to Bhayander, via Mira Road.[76] Preliminary plans prepared jointly by MMRDA and DMRC, proposed a 9 km elevated extension of Metro 7 from Dahisar to Bhayander, via Mira Road.

The extension will be of 11 km and will have 10 stations, with an inter-station distance of 1 km. The line will run parallel to the Surat-Dahisar Highway, then turn left at Kashi Mira Junction, before passing through Mira Road-Bhayander, and terminating at Golden Nest Circle, Bhayander.

The project is estimated to cost 3,908 crore (US$570 million) with an estimated ridership of– 2.5 Lakh.[77][78][79][80]

Line 11Edit

In November 2018, the MMRDA cleared the Metro 11, which connects Wadala with CSMT. This would be considered to be an extension to Metro 4. The length of the line is 11.4 km, and it proposed to cost Rs. 8,739 crore (US$1.207 billion). The line will be partially underground, with 8 underground and 2 elevated stations.

In another boost to connectivity, the Mumbai Metropolitan Region Development Authority (MMRDA) has decided to connect Mumbai and Virar with a Metro line.

Rolling stockEdit

RIIL consulted a number of major international rolling stock builders to provide the train fleet for the Mumbai Metro. Bidders for the contract included established metro-vehicle manufacturers such as Kawasaki, Alstom, Siemens and Bombardier, but CSR Nanjing of China was ultimately chosen to supply rolling stock for Rs 6 billion.[81][82] In May 2008, CSR Nanjing completed the first 16 trains, each comprising four cars.[83] The first ten trains were reported to be ready for operation in January 2013.[84]

The coaches are fire retardant,[85] air-conditioned and designed to reduce noise and vibration, and will feature both high seating capacity and ample space for standing passengers. They will be outfitted with a number of features for safety and convenience, including LCD screens, 3D route maps, first-aid kits, wheelchair facilities, fire-fighting equipment and intercom systems permitting communication with the train driver. Each coach will furthermore feature a black box to assist in accident investigations.[86] The trains will be capable of carrying over 1,100 passengers in a four-car unit, with each carriage being approximately 2.9 metres (9.5 ft) wide.[87]

In 2018, the MMRCL chose Alstom to supply 31 six car trains for Line 3. The trains will be capable of driverless operations and will be built at Alstom's factory in Sri City, Andhra Pradesh.[88][89]

In 2018, MMRDA awarded a tender to Bharat Earth Movers (BEML) to supply 63 trainsets (378 coaches) for Lines 2 and 7 at a cost of ₹3,015 crores ($427.33 million). Capable of driverless operations, the trains will be manufactured at BEML's factory in Bengaluru and will be delivered between 2020 and 2022.[90][91]

Power supplyEdit

Unlike 97% of metro corridors worldwide which run on direct current (DC), the Mumbai Metro runs on alternating current (AC) which is 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.[92]

Signalling and communicationsEdit

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 11-kilometre (6.8 mi) Line 1. A four-minute service interval is anticipated on the route.[2]

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.[93]


In May 2018, just short of Line 1's fourth anniversary, MMOPL said that the line had carried 400 million (40 crore) passengers, with an average daily ridership of around 335,000 (3.35 lakh) passengers.[94]
