India’s first metro

Welcome to the Kolkata Metro

The Kolkata Metro is the oldest metro system in India — the first line opened in 1984. Today it has grown into a five-line network of 55 stations covering around 73 km, operated by Metro Railway, Kolkata (a zone of Indian Railways). It carries the city beneath the Hooghly river, along the colonial core, out to the IT hubs and southern suburbs and direct to the airport.

Frequently asked questions

The Blue and Green lines run about 06:00 to 22:30 Monday to Saturday and from 09:00 on Sundays (timetable in force since 27 July 2026 on an experimental basis). The Yellow Line runs about 07:18–21:58 on weekdays (to 21:30 on Saturdays, 09:18–21:30 on Sundays); the Purple Line runs on weekdays (about 06:40–21:26) and on Saturday afternoons; the Orange Line runs Monday to Friday only (about 08:00–20:05). See the schedule page.
Fares are distance-based and among the lowest in India: ₹5–₹25 on the Blue Line and ₹5–₹30 on the other lines. A journey that changes lines is charged the sum of each line’s fare on one ticket. You can pay with a QR ticket (from the counter, a vending machine or the Aamar Kolkata Metro app) or the rechargeable Metro Smart Card.
Five: the Blue Line (Dakshineswar ↔ Kavi Subhash; trains currently terminate at Shahid Khudiram), the Green Line / East–West Metro (Howrah Maidan ↔ Salt Lake Sector V), the Purple Line (Joka ↔ Majerhat), the Orange Line (Kavi Subhash ↔ Beleghata) and the Yellow Line (Noapara ↔ the airport at Jai Hind). A sixth line, the Pink Line, is planned.
You can interchange between the Blue and Green lines at Esplanade, between the Blue and Orange lines at Kavi Subhash (suspended since 28 July 2025, while the Blue Line platforms there are closed), and between the Blue and Yellow lines at Noapara. The Purple Line is currently a standalone segment until its Esplanade extension opens.
Partly. The newer stations generally have lifts, but no step-free access to the platform is recorded at 12 stations of the original Blue Line tunnel. Check each station page before you travel; trains have priority seating.
