Urban metro rail expanded dramatically after 2014 — from about 248 km across five cities to over 1,000 km in more than 20 cities by 2025. What began as a handful of systems, led by the Delhi Metro, became one of the fastest metro-building programmes in the world, extending into cities like Pune, Nagpur, Kanpur and Kochi.
Metro Rail
Operational metro rail expanded from about 248 km in 2014 to over 1,000 km by 2025, and now runs in more than 20 cities. The counter shows total route length in operation.

| Year | Metro rail in operation |
|---|---|
| 2014 | 248 km |
| 2015 | 296 km |
| 2016 | 350 km |
| 2017 | 425 km |
| 2018 | 515 km |
| 2019 | 670 km |
| 2020 | 697 km |
| 2021 | 748 km |
| 2022 | 810 km |
| 2023 | 905 km |
| 2024 | 1,000 km |
| 2025 | 1,013 km |
Why it matters Metro systems move large numbers of people quickly with low emissions, easing road congestion in major cities.
- Operational metro: ~248 km (2014) → ~1,013 km (2025)

History
Notable projects
Landmark lines mark the era. Kolkata's East-West Metro runs India's first under-river tunnel beneath the Hooghly, while the Namo Bharat Regional Rapid Transit (Delhi–Meerut) introduced India's first semi-high-speed regional rail. Most rolling stock is now built in India under 'Make in India', and cities from Ahmedabad to Bengaluru have opened major new corridors.
How it works
Metros are usually built and run by a special-purpose company jointly owned by the central and state governments (like DMRC in Delhi), which keeps each project focused and professionally managed. Lines are planned around expected ridership and funded through a mix of government equity, cheap long-term loans (often Japanese JICA finance) and property development around stations. Fares alone rarely cover costs, so the model leans on transit-oriented development — dense housing and offices clustered near stations.
Outlook
Metro networks continue to grow across tier-1 and tier-2 cities, with new lines under construction in most major metros and the Namo Bharat RRTS expanding to more corridors around Delhi. The focus is shifting toward integrated urban mobility — linking metro, suburban rail, buses and last-mile services under common ticketing.
The road ahead
The next step is helping the newer systems pay their way — lifting ridership toward projections and pairing each line with dense, transit-oriented development around stations.
By the numbers
248 → 1,013 km operational metro (2014→2025). 5 → 20+ cities with metro. India's first under-river metro (Kolkata) and semi-high-speed RRTS (Namo Bharat). Sources: Ministry of Housing & Urban Affairs, PIB.
