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-longest operational metro network in India with an operational length of 76.95 kilometres (47.81 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 68 operational metro stations of Namma Metro as of November 2024, there are 59 elevated stations, eight underground stations and one at-grade station. The system runs on standard-gauge tracks.
Bengaluru 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 grew to six coaches as ridership increased. Power is supplied by 750V direct current through third rail. As of March 2024, the metro system had an average daily ridership of about 636,000 passengers. On 6 December 2024, the ridership was 9.2 lakh, the highest recorded so far in the history of Namma Metro.
On 9 February 2025, Namma Metro increased its fares, making it the costliest metro system in India. The fare hike resulted in an over 100% increase on certain routes, later capped at 71% following public backlash. This led to a decline in ridership and widespread criticism from commuters and civic groups. Concerns were raised that the fare increase would discourage public transport usage and encourage private vehicle dependency, exacerbating Bengaluru’s already severe traffic congestion.
