== Background == The State Town Planning Department had recommended looking into a mass rapid transit project, i.e. a metro for Bengaluru city, back in 1977. A high-level Committee had also agreed that a metro study was warranted and a team from Southern Railway (SR) was commissioned to do this in 1981. The Southern Railway team recommended a two-corridor metro, {{Cvt|80|km|1}} in length, in addition to commuter rail lines and a circular railway.<ref name="RT">{{Cite web|url=http://documents.worldbank.org/curated/en/677581468043732290/pdf/626100WP0India00Box0361488B0PUBLIC0.pdf|title=Towards a discussion of support to Urban Transport development in India|website=documents.worldbank.org}}</ref>

In 1993, the State of Karnataka established another committee to look into mass rapid transit. This committee had again recommended the same metro project put forward by SR in 1983 along with the same circular railway.<ref name="RT" /> The state then created Bangalore Mass Rapid Transit Ltd (BMRTL) in 1994, with terms of reference to seek a public/private partnership for a mass rapid transit project. The government immediately introduced a special city cess dedicated to the anticipated mass rapid transit project. BMRTL commissioned a feasibility study which came up with an elevated, LRT-based, {{Cvt|300|km|1}} long network on six routes. A private consortium led by United Breweries Group undertook further development of the project on BOT basis. However, the project hadn't taken off.<ref name="RT" />

Later in 2003, the Government of Karnataka commissioned the Delhi Metro Rail Corporation (DMRC), which had successfully developed the Delhi Metro, to carry out a detailed preparation study for a metro in Bengaluru, to be done emulating the technical and financial aspects of the approach used in Delhi. The study recommended a 2-line cross shaped metro, {{Cvt|60|km|4=1}} and {{Cvt|50|km|1}} in length respectively. The intersection of the cross was to be at the Central Railway Station in Bengaluru, completely underground. The economic rate-of-return was forecast at 22.3%. The financial forecast assumes a government subsidy for interest payments and some depreciation, i.e. fare revenue would cover somewhat more than direct operating costs. The Government accepted this option. BMRTL ceased to exist and was replaced by Bengaluru Metro Rail Corporation Ltd (BMRCL).<ref name="RT" />

DMRC prepared and submitted the detailed project for the first phase of Namma Metro in May 2003.<ref>{{Cite web |title=Groundwork for 3 metro rail projects by year-end |url=https://update.im.rediff.com/money/2003/may/14metro.htm |archive-url=https://web.archive.org/web/20250909202654/https://update.im.rediff.com/money/2003/may/14metro.htm |archive-date=2025-09-09 |access-date=2025-09-09 |website=update.im.rediff.com}}</ref> The DPR was for a 2-lined cross shaped {{Cvt|33|km|2}} network with 32 stations for Phase-1 of the project, using standard gauge.

Detailed Project Reports (DPR) for a northern extension (from Yeshwanthapura to Nagasandra) and a southern extension (from Rashtreeya Vidyalaya Road to Yelachenahalli) of north–south corridor (named Green Line later) was submitted in October 2007 and June 2008 respectively. With these extensions, the total route length for Phase 1 became {{Cvt|42.3|km|2}}. The objective was to connect the metro to the Outer Ring Road at northern and southern ends, and also cover the industrial areas of Peenya in the north-west, thereby providing better connectivity and increasing ridership. In October 2008, the Government of Karnataka approved this extension, which would cost an additional ₹1,763 crore (US$250 million).<ref>{{Cite web|date=17 July 2008|title=Bangalore Metro seeks Rs 1,763 cr for extension work|url=https://www.financialexpress.com/archive/bangalore-metro-seeks-rs-1763-cr-for-extension-work/335990/|access-date=2 September 2020|website=The Financial Express|language=en-US}}</ref>

However, it was delayed and finally opened on 1 March 2014.<ref>{{cite news|date=28 February 2014|title=CM in a hurry, delays Namma Metro launch|newspaper=The Hindu|url=http://www.thehindu.com/news/cities/bangalore/cm-in-a-hurry-delays-namma-metro-launch/article5737303.ece|access-date=27 March 2014}}</ref> BMRCL MD Pradeep Singh Kharola stated that about 25,000 passengers travelled on the line on the opening day.<ref name="Deccan_Herald-2014-03-03"/> In the first month of operations, 7.62 lakh people used the line, at an average of 24,605 daily, generating revenues of ₹1.5 crore (US$210,000).

The first underground section (on the Purple line) commenced operations on 30 April 2016, providing connectivity between the east and west of the city. Subsequently, the second underground section, along with southern reaches (viz. Reach 4, 4A) was opened on 18 June 2017.<ref>{{cite news|title=Byappanahallimg road metro stretch more popular|newspaper=The Hindu|url=http://www.thehindu.com/news/cities/bangalore/byappanahallimg-road-metro-stretch-more-popular/article5876934.ece}}</ref>

Once the east and west reaches were inter-connected with opening of the underground section of the purple line, ridership surged significantly. After the north–south underground section was opened (simultaneously with the elevated reach 4,4A in the south), the network provided connectivity in all four directions with interchange between the lines and this further increased ridership. Ridership kept increasing and was around 4,50,000 daily (September 2019).<ref name="HR">{{Cite web|title=At 4.58 lakh passengers, Namma Metro records highest ridership on Friday|url=https://www.newindianexpress.com/cities/bengaluru/2019/sep/01/at-458-lakh-passengers-namma-metro-records-highest-ridership-on-friday-2027307.html|access-date=2 September 2020|website=The New Indian Express|date=31 August 2019 }}</ref>

Since Bengaluru International Airport Limited (BIAL) forbade underground construction from the southern side of the airport (due to security as it would have to pass beneath the airport's second runway), the shortest route options (i.e. extending the Pink line from Nagawara directly north) were eliminated. An alternate route proceeding north till RK Hegde nagar and then turning west to Jakkur was then explored. However, even this had an obstacle as a high-pressure petroleum pipeline was passing through the originally proposed route.<ref>{{Cite web|title=Bengaluru Metro airport line to now run through Hebbal|url=https://www.newindianexpress.com/cities/bengaluru/2018/oct/12/bengaluru-metro-airport-line-to-now-run-through-hebbal-1884445.html|access-date=2 September 2020|website=The New Indian Express|date=12 October 2018 }}</ref>

==== Phase 2, 2A, and 2B lines and sections ==== Phase 2 originally involved extending four reaches of the two lines in all directions and two new lines; Yellow and Pink. The ORR-East Line was later included as Phase 2A followed by the Airport Line (as a continuation of the ORR-East Line) as Phase 2B. The line was later named the Blue Line.

===Rolling stock=== BMRC procured 150 metro coaches for fifty three-car train sets in DMC-TC-DMC formation for Phase l of Namma Metro from BEML – Hyundai Rotem, at a cost of Rs 1,672.50 crore (Rs 16.72 billion). Coach specifications were as follows: length 20.8m, width 2.88m, and height 3.8m. Each coach had a seating capacity of about 50 and standing capacity of 306 (basis 8 per sqm). Thus, each train had a capacity of about 1000. Traction is through four 180 kW motors in each motor coach. The trains have a maximum speed of 80 kmph and axle load of 15 tonnes. The trains operate on 750V DC with third rail bottom power collector system. Features include stainless steel body fully air-conditioned coaches, longitudinal bank of wide seats, wide vestibules between coaches, non-skid and non-slip floor surfaces, wi-fi enabled, four wide passenger access doors on each side, wide windows, automatic voice announcement system and electronic information and destination display system.

Initial operations began with three-coach trains. Each train had a capacity of 1000 passengers. As ridership increased, all trains were converted to six coaches.

The first train set made a trial run in December 2010.<ref>{{cite web|url=http://www.railwaygazette.com/nc/news/single-view/view/bangalore-metro-trial.html|access-date=13 February 2011|title=Railway Gazette: Bangalore metro trial|archive-date=27 October 2011|archive-url=https://web.archive.org/web/20111027042834/http://www.railwaygazette.com/nc/news/single-view/view/bangalore-metro-trial.html|url-status=dead}}</ref> In early 2017, BMRC floated tenders for an additional 150 coaches to convert all trains to 6 coach trains on the two Phase 1 routes.<ref>{{cite web|author=Bengaluru, DHNS |url=http://www.deccanherald.com/content/594727/metro-phase-1-set-meet.html |title=Metro Phase 1 set to meet April deadline |work=Deccan Herald |date=4 February 2017 |access-date=11 February 2017}}</ref> On 27 March 2017, BEML announced that it had won an {{INR}}1,421 crore contract to supply the coaches.<ref>{{cite web|title=BEML wins Rs 1,421-cr contract from Bangalore Metro|url=http://www.thehindubusinessline.com/companies/beml-wins-rs-1421cr-contract-from-bangalore-metro/article9602947.ece|website=Business Line|access-date=28 March 2017|date=27 March 2017}}</ref> The first six car train was introduced on the Purple Line on 23 June 2018.<ref>{{cite news|title=Second six-coach Namma Metro train flagged off - Times of India|url=https://timesofindia.indiatimes.com/city/bengaluru/chief-minister-inaugurates-namma-metros-second-six-car-train-fob-at-majestic/articleshow/66066656.cms|access-date=24 January 2019|website=The Times of India|date=4 October 2018 }}</ref> By January 2020, all trains had been converted to six coaches.<ref>{{Cite web|author=Christin Mathew Philip|date=29 Jan 2020|title=All 42 metro trains now have 6 coaches, says BMRCL; passengers want better frequency |url=https://timesofindia.indiatimes.com/city/bengaluru/all-42-trains-now-have-6-coaches-says-bmrcl-passengers-want-better-frequency/articleshow/73744048.cms|access-date=6 September 2020|website=The Times of India|language=en}}</ref>

===Rainwater harvesting=== BMRCL, in a public-private partnership, harvests rainwater from the viaducts on the rail system. The private partner, Karnataka Rural Infrastructure Development (KRIDL), collects the water at multiple points, treats it, and sells it in bulk as potable water.<ref>{{cite news|url=http://www.thehindu.com/news/cities/bangalore/article2716713.ece|title='Liquid' cash from viaduct|work=The Hindu | location=Chennai, India|date=15 December 2011}}</ref> Pipes inside each metro viaduct pillar carry the rainwater from the viaduct down to underground tanks located beneath the median. When these tanks overflow, the water is diverted to 5 metres deep rainwater harvesting pits. Two rainwater harvesting pits are installed between each pillar. The average distance between the two pillars is 28 meters. As of March 2017, a {{convert|33.48|km|abbr=on}} of the elevated metro is covered by the rainwater harvesting system.

BMRCL also harvests rainwater from the 140 acres depot facility at Peenya. Water will be collected from the {{formatnum:190000}} sq foot roof and stored in two tanks with a capacity of 50,000 litres each. Rainwater harvesting is also planned in existing and under-construction stations. The water harvested will be supplied to places where needed, and any excess will be used for groundwater recharge.<ref name="waterwisedna"/>

BMRC has installed a water harvesting system along Reach 1 and will be doing the same for Reaches 3 and 4. Installation of flower beds was delayed due to garbage being dumped on the median by garbage collectors, BMRC will also set up flower beds on Reach 1 with assistance from the horticulture department. However, the work related to this has slowed down due to garbage contractors dumping garbage along the median, due to the lack of a waste management plan in the city.<ref>{{cite news| url=https://m.timesofindia.com/city/bangalore/Metro-medians-turn-garbage-dumps/articleshow/15369170.cms | archive-url=https://archive.today/20130126074840/http://articles.timesofindia.indiatimes.com/2012-08-06/bangalore/33064674_1_garbage-contractors-medians-dump-waste | archive-date=26 January 2013 | work=The Times of India | title=Metro medians turn garbage dumps | url-status=live | date=6 August 2012}}</ref> BMRC also planned to rejuvenate Kengeri and Veerasandra lakes using water collected from a nearby corridor.<ref>{{cite web|url=https://m.timesofindia.com/city/bangalore/Lakes-to-come-alive-along-Metro-path/articleshow/17083346.cms |archive-url=https://archive.today/20130103073341/http://articles.timesofindia.indiatimes.com/2012-11-04/bangalore/34908256_1_n-sivasailam-bmrc-metro-path |archive-date=3 January 2013 |title=Lakes to come alive along Metro path |date=4 November 2012 |work=The Times of India |url-status=live |access-date=4 March 2013}}</ref><ref>{{cite web|url=http://www.dnaindia.com/bangalore/report_bmrcl-plans-to-rejuvenate-lakes-starting-with-kengeri_1759957 |title=BMRCL plans to rejuvenate lakes, starting with Kengeri – Bangalore – DNA |work=Daily News and Analysis |date=4 November 2012 |access-date=4 March 2013}}</ref>

Metro system in Bengaluru charges full fare tickets for children above three years of age which is against the Indian government circular date 6 March 2020, No. TC-II/2910/2016/child fare/VIP. Circular number 12 states that "Children under five years of age shall be carried free and purchase of any ticket is not required". "In case of children of age 5 years to under 12 years of age (in case of no berth) only half of the applicable fare shall be charged and in this case, a minimum distance of charge shall not be applicable". (CC30 of 2017 dated 24 April 2017). Similarly Karnataka government public transport system does not collect fares from children under the age of 6 yrs and half fares from children under 12 yrs of age. Bengaluru metro decided to include 3 ft as a criterion to decide who is classified as a child. The average height of Indian babies at 3 yrs is much more than 90 cms. Since BMRCL is a joint venture of the Government of India and the Government of Karnataka, it should be expected to follow Government of India/ Karnataka rules.

On 26 March 2023, Prime Minister Narendra Modi symbolically launched the long-awaited National Common Mobility Card (NCMC) in Bengaluru while he traveled on the newly inaugurated Whitefield stretch of the Purple Line using the NCMC.

===Ridership=== The Purple Line's Reach-1 of 6.7 km was the first to open, in October 2011. On the first three days of operations of Reach-1, 169,019 people rode the metro.<ref name="HR"/> At the end of the fourth day, about 200,000 passengers had already commuted on Namma Metro. In the first month since opening of Reach-1, about 1,325,000 people had travelled by metro. Thus, on average, 41,390 people took the train each day during the first month. However, the average ridership in the first six months of operation dropped to 24,968.<ref name="FT"/>

The northern section of the Green Line (Reach 3, 3A - 9.9 km) opened in March 2014. About 25,000 passengers travelled on the northern section on the opening day.<ref name="Metro_Green_Line_Launch"/> In the first month of operations of the Green Line stretch, 762,000 people used the line, at a daily average of 24,605.

Reach-1, Reach-3/3A and Reach-2 (opened in November 2015) operated independently until the east–west underground section of Purple Line (connecting Reaches 1 and 2) was opened in April 2016. Once the east and west reaches were inter-connected with the intermediate underground section of the Purple Line, ridership surged hugely to nearly 100,000 a day on the line in the first few days.<ref>{{Cite web|last=Service|first=Indo-Asian News|date=2016-05-02|title=Record one lakh commuters travel in Bengaluru metro on Sunday|url=https://www.india.com/news/india/record-one-lakh-commuters-travel-in-bengaluru-metro-on-sunday-1152129/|access-date=2021-08-23|website= India.com|language=en}}</ref> After the north–south underground section was opened (simultaneously with the elevated reaches 4,4A in the south), the network provided connectivity in all four directions with interchange between the lines and this increased ridership further, reaching between 350,000 and 360,000 on average by December 2017.<ref>{{Cite web|title=17 crore passengers have boarded Bengaluru Metro since 2011|url=https://www.newindianexpress.com/cities/bengaluru/2017/dec/29/17-crore-passengers-have-boarded-bengaluru-metro-since-2011-1739328.html|access-date=2021-08-23|website=The New Indian Express|date=29 December 2017}}</ref>

As ridership kept growing, overcrowding became a serious concern. Hence, 3-coach trains began to be converted to 6 coaches. The first six car train was introduced on the Purple Line on 23 June 2018. By January 2020, all trains had been converted to six coaches.<ref name="TimesofIndia2016"/>

During 2019–20, the annual ridership was 174.22 million (average during the year was thus 477,315). The maximum daily ridership of 601,164 was on 25 October 2019 while the highest daily revenue of Rs.1.67 crore was on 2 March 2020. In January 2020, ridership averaged 518,074.<ref name="JN"/>

The BMRCL had not informed of the drill in advance.<ref>{{cite web|title=Mock drill at Metro stations takes passengers aback|url=http://www.deccanherald.com/content/603206/mock-drill-metro-stations-takes.html|website=Deccan Herald|access-date=26 March 2017|date=26 March 2017}}</ref>
