Namma Metro
Namma Metro (transl. Our Metro), also known as Bengaluru Metro, is a rapid transit system serving the city of Bengaluru, the capital city of the state of Karnataka, India. It is the second-largest metro network in India with an operational length of 96.1 km (51.7 mi), behind Delhi Metro. Upon its inauguration in 2011, it became the first metro system in South India, and subsequently in 2016, the first underground metro in South India as well. Namma Metro has a mix of underground, at grade, and elevated stations. Out of the 83 operational metro stations of Namma Metro as of August 2025, there are 74 elevated stations, eight underground stations and one at-grade station. The system runs on standard-gauge tracks.
Bangalore Metro Rail Corporation Limited (BMRCL), a joint venture of the Government of India and the State Government of Karnataka, is the agency for building, operating and expanding the Namma Metro network. Services operate daily between 05:00 and 24:00 running with a headway varying between 3–15 minutes. The trains initially began with three coaches but later, all rakes were converted to six coaches as ridership increased. Power is supplied by 750V direct current through third rail.
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, 80 km (49.7 mi) in length, in addition to commuter rail lines and a circular railway.
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. 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, 300 km (186.4 mi) 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.
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, 60 km (37.3 mi) and 50 km (31.1 mi) 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).
Delhi Metro Rail Corporation Limited (DMRC) prepared and submitted the detailed project for the first phase of Namma Metro in May 2003. The DPR was for a 2-lined cross shaped 33 km (20.51 mi) network with 32 stations for Phase-1 of the project, using standard gauge. The project was approved by the Union Cabinet on 25 April 2006.
The foundation stone for construction of Phase-1 was laid by then Prime Minister Dr. Manmohan Singh on 24 June 2006. Navayuga Engineering Company Limited was awarded the first contract to construct Reach-1 of the east–west corridor (named Purple Line later) in 2006. Civil construction on the first section (Reach-1) of the Purple Line between Baiyyappanahalli and Mahatma Gandhi Road, commenced on 15 April 2007.
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 42.3 km (26.28 mi). 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).
