Indian metro route length by August 2025: where cities stand

India’s metro rail buildout has shifted from a handful of legacy systems to a nationwide network exceeding 1,000 route kilometres, with fresh data for August 2025 highlighting how Delhi, Mumbai, Bengaluru and a growing roster of tier‑two cities now share the map. Publicly available figures show not only what is running today, but also how much track is under construction or in advanced planning across the country’s largest urban centres.

National snapshot: India’s metro footprint crosses 1,000 km

Recent figures from government press releases and sector analyses indicate that India’s operational metro network has expanded from about 248 km in 2014 to more than 1,000 km by mid‑2025, spanning over 20 cities with full metro or metro‑lite systems. An update issued in 2025 places the operational total at roughly 1,095 km when suburban rapid transit such as the Delhi–Meerut Regional Rapid Transit System is included, underlining how quickly urban rail has moved from experiment to backbone of city transport.

Independent compilations that draw on Ministry of Housing and Urban Affairs data, metro operator reports and state submissions suggest that, as of August 2025, India has around 1,050 to 1,100 km of conventional metro lines in service. Alongside this, approximately 500 to 600 km of additional corridors are under construction, and several hundred more kilometres are at the detailed project report or approval stage. The numbers vary slightly by source, but they consistently show that India is closing in on the world’s second‑largest urban rail footprint.

Sector trackers note that the growth is also spreading beyond the original five systems of Delhi, Kolkata, Bengaluru, Mumbai and Chennai. Cities such as Ahmedabad, Kochi, Nagpur, Lucknow, Kanpur, Agra and the twin projects in Bhopal and Indore together now account for well over 200 km of operational lines, while multiple second‑phase buildouts are underway. In effect, most major state capitals either have a metro in service or have secured approvals for one.

Delhi NCR and northern metros: dense networks and new phases

Delhi and its surrounding National Capital Region remain India’s largest single metro market. Publicly available information from Delhi Metro Rail Corporation and government press material indicates that the core Delhi Metro network is operating at well above 390 km of route length in August 2025 when all lines and extensions are counted, complemented by the 82 km Delhi–Ghaziabad–Meerut rapid rail corridor that is being opened in stages. Phase IV of the Delhi network alone covers more than 110 km of approved lines, much of which is under active construction, with additional corridors cleared as part of a subsequent Phase V programme.

In Uttar Pradesh, state‑level data presented in Parliament and summarised by national media show that by mid‑2025 the state had roughly 147 km of operational metro across Lucknow, Noida–Greater Noida, Ghaziabad, Kanpur and Agra. Lucknow’s first phase of just under 23 km is fully in service, while an 11 km Phase 1B extension received central approval in 2025. Kanpur and Agra continue to add stations on partially opened corridors, and further stretches of the Delhi–Meerut rapid rail are extending high‑speed connectivity into the state.

Other northern cities are in earlier stages but moving into construction. Jaipur’s roughly 12 km of operational metro remains unchanged, yet updated project databases list additional kilometres of elevated track under planning to reach growing suburbs. Chandigarh and surrounding towns have light metro or metro‑lite proposals that appear in national project monitoring dashboards, though these remain in the planning column rather than under construction as of August 2025.

Mumbai, Ahmedabad and western corridors: complex buildouts

Mumbai’s metro programme is among India’s most complicated, combining older elevated lines with long new underground sections. Route‑length tallies from operator updates and specialised transport publications indicate that by August 2025 the Mumbai Metropolitan Region has more than 80 km of metro in operation across several lines, led by Line 1, the Line 2/7 east‑west and north‑south pair, and the newer Line 9 sections. A further 150 km or more is under construction, dominated by the 33.5 km fully underground Line 3, which is in advanced stages of civil and systems work and is being prepared for phased opening around late 2025 to 2026.

The wider Mumbai region also features upcoming systems such as the 29 km Thane ring metro, which received cabinet approval with a completion horizon toward the end of the decade. Together with Navi Mumbai’s developing corridors, these schemes will lift the western region’s total urban rail route length substantially beyond today’s figures, pushing combined operational and under‑construction kilometres above 200 km.

In Gujarat, project summaries from the state‑owned Gujarat Metro Rail Corporation show that the Ahmedabad Metro Phase I network reached just over 40 km in operational length after a short extension opened in late 2024. Phase II adds new routes towards Gandhinagar and GIFT City, with more than 20 km under construction and further branches planned. When the currently sanctioned sections are completed, Ahmedabad and Gandhinagar together are expected to field a metro network approaching 70 km.

Other western systems such as Nagpur are also growing. Nagpur’s first two lines provide over 35 km of operational metro in the city, with approved extensions and a third line adding observable kilometres in the under‑construction category. Combined western‑India data indicate that, by August 2025, Maharashtra and Gujarat alone host well over 150 km of operational metro and a similar scale of projects under execution.

Bengaluru, Chennai and southern India: long corridors and new approvals

The southern metro clusters are led by Bengaluru and Chennai, both of which have embarked on second‑generation expansion plans. Bengaluru’s Namma Metro, according to recent operator reports and state budget documents, operates roughly 73 km of lines across the Purple and Green corridors and their extensions, with the new Yellow Line adding further reach to the southern and eastern suburbs. Approved and under‑construction sections across Phases II, II‑A and II‑B bring the total network length of operational, in‑progress and sanctioned corridors close to 190 km.

Construction in Bengaluru is particularly concentrated along the Outer Ring Road and the airport corridor, where elevated viaducts are now a dominant feature of the skyline. State‑level audit reports note that an additional 40 km of metro is expected to open in the 2026–27 window, pointing to a sustained pipeline of work beyond the August 2025 snapshot. This positions Bengaluru among the fastest‑expanding single‑city metro programmes in India.

Chennai, which opened its first lines in 2015, has meanwhile stabilised an operational network in the range of 54 to 60 km on its Phase I corridors. Phase II, divided into multiple corridors weaving across the metropolitan area, adds well over 100 km of new track and is firmly in the under‑construction column for August 2025. Public dashboards and media coverage describe large construction fronts across the city’s radial roads and central business areas.

Other southern metros, including Kochi and Hyderabad, also contribute significantly to the national totals. Kochi’s single‑line system has grown to around 27 km, with a metro‑lite extension and integration with the city’s water metro raising its profile. Hyderabad, though formally a separate state‑entity network, fielded about 69 km of metro lines by the mid‑2020s, and proposals for additional corridors and airport connections are in various planning and approval stages, keeping a sizeable share of southern expansion in the “planned” category.

Tier‑two cities and future pipeline: under construction and planned km

Beyond the major metros, a distinctive feature of the August 2025 picture is the rise of tier‑two systems. In central India, the Bhopal (Bhoj) Metro brought its first stretch of roughly 6 km into service in late 2025, while keeping more than 20 km of additional route length under construction as part of its initial phase. Indore’s Yellow Line, planned to reach more than 33 km, has an operational pilot section and about 16 km categorised as under construction on recent project summaries.

Pune, another fast‑growing western city, continues to advance its Phase I scheme of around 31 km, with several sections already open and the remaining kilometres under construction. Project maps and local transit analyses show that, once fully commissioned, Pune’s initial buildout will rival older metros in scale, with further extensions and a potential metro‑lite line forming part of the city’s planned network.

In eastern India, Kolkata is reshaping its long‑standing network into a multi‑line grid. The original North–South Line has been joined by the East–West corridor passing under the Hooghly River, while new Orange and Yellow lines add capacity to the eastern and northern suburbs. As of August 2025, publicly available route‑length tables list several tens of kilometres of new Kolkata lines as under construction, with total operational length in the city nearing the 50 km mark and a similar magnitude of track either being built or planned.

Looking across all metros, compilations that aggregate operator data suggest that India’s tier‑two and emerging systems together provide more than 250 km of operational track by August 2025, with around 200 km under construction and a large reserve of planned length awaiting clearances and funding. When combined with the big four of Delhi, Mumbai, Bengaluru and Chennai, this pipeline indicates that India’s urban rail network is on course to more than double its operational route kilometres over the coming decade if projects under construction and formally approved are delivered to schedule.
