Kolkata Metro Overview
Kolkata Metro is India's oldest metro system, operated by Metro Railway Kolkata (part of Indian Railways) and Kolkata Metro Rail Corporation (KMRC). The network runs 52 Kolkata Metro stations across 4 colour-coded lines — Blue, Green, Orange, and Purple — spanning about 66 km of underground, elevated, and at-grade track, with trains running daily from about 6:40 AM to 10:30 PM.
The Blue Line (Dakshineswar–Kavi Subhash, 26 stations), India's original North-South Metro corridor, crosses the Green Line (Howrah Maidan–Salt Lake Sector-V, 12 stations) at Esplanade in the heart of the city, and meets the Orange Line (Kavi Subhash–Beleghata, 9 stations) at Kavi Subhash. The Purple Line (Joka–Majerhat, 7 stations) in the city's southwest is not yet connected to the rest of the network; its extension toward central Kolkata is under construction. Together the lines connect Howrah railway station, the Salt Lake IT corridor, and central Kolkata's business district around Esplanade and Park Street.
Kolkata Metro fare is calculated on a distance-slab basis, with the National Common Mobility Card (NCMC) and the Aamar Kolkata Metro app accepted for smart-card and QR-code ticketing. For travel assistance, the Kolkata Metro helpline is 900-704-1844. MetroYatra provides station-wise Kolkata Metro train timings, route map, fare calculator, and platform details for all 52 stations.

Kolkata Metro Purple Line: TBM Durga Completes Kidderpore-Victoria Tunnel Breakthrough, July 2026
Kolkata Metro's Purple Line reached a tunnelling milestone on 10 July 2026, when tunnel boring machine 'Durga' broke through at the proposed Victoria metro station. The drive from Kidderpore to Victoria took exactly one year, having started on 10 July 2025.
The Purple Line will eventually run 18.84 km from Joka to Esplanade; about 7.74 km between Joka and Majerhat is already operational. Durga and its twin machine 'Divya' will now tunnel beneath the Maidan towards Park Street.
Kolkata Metro Green Line Completes Full East-West Corridor: Sealdah-Esplanade Section Opens, August 2025
Kolkata Metro's Green Line became a single continuous corridor on 22 August 2025, when Prime Minister Narendra Modi inaugurated the final 2.63 km Sealdah-Esplanade stretch. This joined the Howrah Maidan-Esplanade underwater section, opened in March 2024, with the existing Salt Lake Sector V-Sealdah stretch.
The new stretch connects Sealdah, one of India's busiest railway terminals, directly to the Esplanade interchange, cutting the Howrah-to-Sealdah journey from around 50 minutes by road to about 11 minutes by metro.
Kolkata Metro Orange Line Extended to Beleghata: New 4.39 km Stretch Opens, August 2025
Kolkata Metro's Orange Line was extended to Beleghata on 22 August 2025, when Prime Minister Narendra Modi inaugurated the 4.39 km Hemanta Mukhopadhyay-Beleghata stretch. Commercial services began on 25 August 2025, taking the line to eight operational stations in total.
The extension connects Science City, hospitals, colleges and business areas along the route. Trains run from 8 am to 8:05 pm on weekdays with a 25-minute frequency.
Kolkata Metro Blue Line: Kavi Subhash Station Platform to Be Rebuilt After Cracks Found, July 2025
Kolkata Metro shut the Up-line platform at Kavi Subhash station, the Blue Line's southern terminus, on 28 July 2025 after cracks appeared in four columns supporting the platform shed. Metro Railway attributed the damage to uneven foundation settlement following heavy rainfall.
After inspection, Metro Railway found the columns too weak to repair and decided to demolish and rebuild the affected platform, targeting completion within nine months.
Kolkata Metro Rolls Out Multi-Ticket QR Purchase via UPI Across Blue, Green and Orange Lines
Kolkata Metro introduced a multi-ticket QR purchase facility on 28 February 2025, letting commuters buy up to seven paper QR-based tickets in a single UPI transaction. The system covers Blue, Green and Orange line stations.
Previously, passengers could buy only one QR ticket per transaction, leading to long queues at counters. The rollout follows Kolkata Metro's phase-out of paper tokens in January 2025.
Kolkata Metro Green Line Opens India's First Underwater Tunnel: Howrah Maidan-Esplanade Section, March 2024
Kolkata Metro's Green Line opened its Howrah Maidan-Esplanade section on 6 March 2024, when Prime Minister Narendra Modi inaugurated the 4.8 km stretch. It became the first metro line in India to run under a major river, with 520 metres of twin tunnels passing beneath the Hooghly River. Public services began on 15 March 2024.
The section has four stations: Esplanade, Mahakaran, Howrah and Howrah Maidan. Howrah station sits about 33 metres below ground, the deepest metro station in India.
Kolkata Metro Purple Line Extends to Majerhat: Taratala-Majerhat Section Opens, March 2024
Kolkata Metro's Purple Line extended to Majerhat on 6 March 2024, when Prime Minister Narendra Modi remotely inaugurated the 1.25 km Taratala-Majerhat stretch at a cost of around Rs 530 crore, joining the Joka-Taratala section opened in December 2022.
The Joka-Majerhat stretch now covers 7.75 km. Majerhat is an elevated station built directly over an existing Indian Railways line, the first such construction on the Kolkata Metro network.
Kolkata Metro Orange Line Begins Service: Kavi Subhash-Hemanta Mukhopadhyay Section Opens, March 2024
Kolkata Metro's Orange Line began operations on 6 March 2024, when Prime Minister Narendra Modi inaugurated the Kavi Subhash-Hemanta Mukhopadhyay section. The 5.4 km stretch, built at a cost of around Rs 1,440 crore, included five stations: Kavi Subhash, Satyajit Ray, Jyotirindra Nandi, Kavi Sukanta and Hemanta Mukhopadhyay.
