Bangalore (Namma) Metro is an urban Mass Rapid Transit System (MRTS) with 2 lines and 51 stations serving Bengaluru, Karnataka’s capital and largest city.
Construction for Bangalore Metro Phase 1 with 42.30 km of routes started in April 2007. Its first section, connecting Baiyyappanahalli – MG Road on the Purple Line, opened up in 2011. The 6th (and final) section was inaugurated by India’s President on June 17 2017 and commercial operations started on the next day.
Construction work on the 73.921 km Bangalore Metro Phase 2‘s first new section (Mysore Road – Pattanagere, Reach-2A of Purple Line) started in September 2015. The project faced funding issues due to which a majority of civil construction contracts were awarded only in the first half of 2017. While the Green Line’s extension to Silk Institute became operational in January 2021, the entire phase, including a 13.9 km underground section of the Pink Line, is expected to be ready no sooner than 2024 after which the metro network will become 116.25 km long.
Bangalore Metro’s Phase 3 project with routes totalling 105.55 km is currently on the drawing board. From that, 18 km (Central Silk Board – KR Puram) and 38 km (KR Puram – KIAL Airport) of lines have been expedited and will be built in parallel with Phase 2 under Phase 2A and Phase 2B respectively.

Details : Phase 2A
Bangalore (Namma) Metro’s Phase 2A project with one new 18.236 km elevated line, connecting KR Puram with Central Silkboard along the Outer Ring Road (ORR), was first announced at the Invest Karnataka Summit in February 2016 and is planned to be constructed along with the 73.92 km Phase 2 project. Bangalore Metro Rail Corporation Ltd. invited bids for geotechnical investigation and DGPS, topographic, land & property surveys in June 2016. The line’s Detailed Project Report (DPR), prepared by BMRCL’s in-house team, was revealed in November 2016 and estimates the line’s construction & system procurement to cost Rs 4202 crores.
The Karnataka government’s cabinet approved the project’s DPR in March 2017. Back then, instead of relying on foreign lenders, the BMRCL had planned to fund this line through what it called an “innovative financing model” in which private entities would have been engaged to pitch in anywhere from 25% to 50% of the line’s construction cost (Rs. 1100-2100 crores) and in return be granted exclusive advertising and leasing rights within the stations to monetize on their investment. By February 2018, BMRCL had only signed only 2 MoUs worth approximately Rs 100 crore each.
In 2018-2019, the BMRCL invited bids for the line’s construction in 3 packages. During that time, BMRCL was unable to achieve financial closure and the lowest bidder for all 3 packages, IL&FS Engineering and Construction Company Limited, was hit by financial troubles. In December 2019, BMRCL re-invited tenders for its construction. Technical bids were opened in March 2020 to reveal 9 bidders, and financial bids were opened in October to reveal Afcons Infrastructure and Shankarnarayana Construction as the lowest bidders. Construction contracts were awarded in May 2021.
In April 2021, Phase 2A was approved by the Central Government’s cabinet. Phase 2A and Phase 2B (KR Puram – Yelahanka – Bangalore Airport) will be funded through a $500 million loan by the Asian Development Bank (ADB) which was approved by its board in December 2020. In addition, Japan International Cooperation Agency (JICA) will provide a $318 million loan as well. A formal agreement for it was signed in March 2021.
Funding (Phase 2a)
Estimated Cost : Rs. 5,227.35 crore
ADB : Rs. 1,479.46 crore
JICA : Rs. 893 crore (preliminary negotiation)
PPP Sources : Rs. 600 crore
State Govt : Rs. 1,690.46 crore
Central Govt : Rs. 734.22 crore
Line-5 (Blue Line) : KR Puram – Central Silkboard
- Length : 18.236 km
- Type : Elevated
- Number of Stations : 13
- Station Names : KR Puram (interchange with the under construction Purple Line), Mahadevpura, DRDO Sports Complex, Doddanakundi, ISRO, Marathahalli, Kodibisanahalli, Kadubeesanahalli, Bellandur, Ibbalur, Agara Lake, HSR Layout, Silk Board (interchange with the upcoming Yellow Line).
- Depot : Trains on the ORR line will be stabled and & maintained at the existing Baiyappanahalli Depot. Some of the Purple Line’s existing stabling lines will be re-purposed for this line and due to that, a new depot for the Purple Line will be built at Kadugodi near Hope Farm Junction (view suggested layout) where government land is available. At a later stage, the Baiyappanahalli Depot will exclusively be used by this new line’s trains while the Purple Line’s trains will be stabled & maintained at Kadugodi Depot and Challaghatta Depot.
- Rolling Stock : BMRCL plans to initially procure 120 coaches (20 train-sets x 6 coaches), and operate them in a DMC-TC-MC+MC-TC-DMC formation from the get-go.
Details : Phase 2B
37 km Bangalore (Namma) Metro Phase 2B project is an under construction “airport-link” section of Blue Line from Bengaluru city to Kempegowda International Airport (KIAL) in Devanahalli with 17 stations.
A metro line to the airport has been on the drawing board since 2005 when construction commenced on the city’s airport. It was first envisioned as a high-speed rail link connecting the city’s CBD (MG Road) to be executed by a special purpose vehicle independent of the Bangalore Metro Rail Corporation.
In October 2015, RITES suggested 2 routes to the Bangalore Metro Rail Corporation (BMRCL). In September 2016, BMRCL sought suggestions from the public on 9 routes; they went on to finalize 4 routes in late-April 2017. In May 2017, they picked the route extending Line-4 via Nagawara, RK Hegde Nagar, Jakkur & Yelahanka. In January 2019, the Karnataka Government announced the approval of the line’s 37 km route with 17 stations as an extension of Line-5 (ORR Line) via KR Puram, Nagawara, Hebbal & Yelahanka.
Phase 2A and Phase 2B (KR Puram – Yelahanka – Bangalore Airport) will be funded through a $500 million loan by the Asian Development Bank (ADB) which was approved by its board in December 2020. In addition, Japan International Cooperation Agency (JICA) will provide a $318 million loan as well. A formal agreement for it was signed in March 2021.
In April 2021, Phase 2B was approved by the Central Government’s cabinet. BMRCL has not published Phase 2B’s DPR (Detailed Project Report) online.

Bangalore Metro Rail Corporation Limited (BMRCL), a joint venture of Government of India and Government of Karnataka, is a Special Purpose Vehicle entrusted with the responsibility of implementation and operation of Bangalore Metro Rail Project.
Bangalore Metro, christened as “Namma Metro”, not only adds to the beauty of Bangalore city skyline, but more importantly provides a safe, quick, reliable and comfortable public transport system. Besides this, Namma Metro is a major environment friendly addition to the Bangalore City as it significantly contributes to the reduction of carbon emissions.
Metro services have been in operation on 56 KM on East-West corridor – 25.6 km long, starting from Baiyappanahalli in the East and terminating at Kengeri Terminal in the West and on 30.4 km North-South corridor commencing at Nagasandra in the North and terminating at Silk Institute in the South. This is the First Metro rail project in India commissioned with 750V DC Third Rail Traction on Standard Gauge. Bangalore Metro is developing fast and expected to help in decongesting the city traffic significantly. The city is popularly called the IT capital of India and is amongst one of the fastest growing cities of the world.
