Kolkata Metro Map 2026: Lines, Tickets & Prices

Kolkata Metro Map 2026: key facts at a glance

• Five colour-coded lines are open to passengers, and their commissioned corridors total 73.0 km. On the Blue Line you currently travel only between Dakshineswar and Shahid Khudiram, because services on to Kavi Subhash have been suspended since 28 July 2025.
• The airport sits on the Yellow Line at Jai Hind Bimanbandar, served on weekdays from about 07:20 until just after 21:00 roughly every twelve minutes. Change at Noapara for the Blue Line into central Kolkata.
• You pay by distance, starting at ₹5.00. The published brackets of 22 May 2024 go up to ₹25.00 on Blue, ₹30.00 on Green and Orange, and ₹20.00 on the open Purple section.
• Blue Line trains work to an interval of about five minutes, though that is not an all-day guarantee. Intervals, first trains and last trains differ on the other lines and from day to day.
• Green takes you right across the city from Howrah Maidan to Salt Lake Sector V. Purple currently ends at Majerhat, Orange at Beleghata and Yellow at the airport.

Current Kolkata Metro service updates

Service patterns can change by corridor, day and special event. Check the line-specific timetable before an evening, weekend or airport trip. In particular, Blue Line trains currently run only between Dakshineswar and Shahid Khudiram, because services to Kavi Subhash have been suspended since 28 July 2025.

The Kolkata Metro map puts the current passenger corridors, transfers and airport branch into one view. This guide explains which sections are in service, how the published fare brackets work and where an unfinished extension must not be mistaken for an open route.

Metro Railway’s operator portal labels its whole-system plan as updated on 25 August 2025 and presents it as an embedded image rather than a standalone PDF.

Kolkata opened India’s first metro in 1984, and its East-West corridor includes the country’s first underwater metro transportation tunnel beneath a major river. The March 2026 Ministry corridor table records commissioned passenger sections on five colour corridors, with lengths adding up to 73.0 km.

Services are run within Indian Railways by Metro Railway, Kolkata, which is a zonal railway. Kolkata Metro Rail Corporation Limited, or KMRCL, implemented the Green Line East-West corridor as a Government of India enterprise. It should not be presented as a separate citywide passenger operator.

Howrah connects the Green corridor with the railway complex. Treat it as an interchange point and use the relevant railway information for the onward journey.

The 73.0 km figure is a commissioned-corridor total. It should not be read as a promise that every platform or terminus is available on a particular day. That distinction matters on Blue, where the corridor is officially commissioned to Kavi Subhash but commercial services between Shahid Khudiram and Kavi Subhash have been suspended since 28 July 2025, so trains currently run only to Shahid Khudiram.

Kolkata Metro lines currently in service

• Blue Line: The commissioned north-south corridor covers 32.1 km from Dakshineswar to Kavi Subhash through central stations such as Esplanade, Park Street and Maidan. However, commercial services between Shahid Khudiram and Kavi Subhash have been suspended since 28 July 2025, so trains currently run only between Dakshineswar and Shahid Khudiram.
• Green Line: The 16.6 km East-West corridor is fully operational from Howrah Maidan to Salt Lake Sector V. Esplanade provides the connection with Blue, while Howrah connects with the railway complex.
• Purple Line: Passenger service covers 7.7 km from Joka to Majerhat. The continuation toward Esplanade is construction work and is not part of the open passenger section.
• Orange Line: The commissioned 9.8 km section runs from Kavi Subhash, also called New Garia, to Beleghata. Because Blue trains do not currently reach Kavi Subhash, the Blue-to-Orange interchange there is not available at present, even though Orange services still start from Kavi Subhash.
• Yellow Line: Passenger service covers 6.8 km from Noapara to Jai Hind Bimanbandar. Noapara is the supported transfer point with Blue, while the route beyond the airport remains unfinished.

The Kolkata Metro route map is most useful when read with the line status table below. Green is complete as an operating corridor, but Purple, Orange and Yellow all have extensions that belong in construction updates, not in a list of places passengers can already reach.

The status distinction is especially important at Kavi Subhash. Because Blue trains do not currently reach Kavi Subhash, the Blue-to-Orange interchange there is not available at present, even though Orange services still start from Kavi Subhash. Reaching Orange from the Blue Line requires an alternative route until Blue services to Kavi Subhash resume.

The network reaches central Kolkata, Howrah, Dakshineswar and Netaji Subhas Chandra Bose International Airport. The destinations table below uses officially named stations where possible. For Eden Gardens and Science City, it identifies suggested railheads and states where an onward local connection is required.

This Kolkata Metro map turns named stations and careful onward connections into practical trip planning. It also avoids a common error: a future station or geographically close railhead does not become a direct visitor connection until an official source and the final local transfer support that conclusion.

Yellow serves Jai Hind Bimanbandar, and a subway connects the station with the airport terminal. Ride to Noapara to transfer to Blue for central Kolkata. Allow extra time for the transfer and consult the current timetable, since no reliable official end-to-end airport journey time was found.

Fares are distance-based, with different published brackets by line. The operator’s published fare matrix is dated 22 May 2024, so the prices below are a dated reference rather than proof of a complete network-wide July 2026 tariff.

Passengers can use stored-value Smart Cards or mobile QR tickets. The official Aamar Kolkata Metro app is provided by the Centre for Railway Information Systems (CRIS) on Android and iPhone. An October 2025 Ministry release says app tickets are discounted but does not state a percentage.

USD conversions use the Reserve Bank of India reference rate of ₹96.2537 to US$1 at 1:00 pm on 21 July 2026. Rounded conversions are approximate.

For a Smart Card, touch the card at the automatic fare collection gates when entering and leaving so the journey fare can be deducted. Confirm current card deposits, bonuses and maximum balances at the station before paying.

For a QR ticket, select the journey in Aamar Kolkata Metro and use the generated code at the entry and exit gates. The store listings also support linking and topping up a stored-value Smart Card. Both app stores identify CRIS as the provider.

The official app is available for Android and iPhone.

Operating hours differ by corridor. On the Blue Line, first trains run from about 06:00 and last trains leave the terminals around 22:30, at roughly six to seven minute intervals during the day. The Green Line runs from about 06:40 until around 22:05 on weekdays and Saturdays, but only from 09:00 on Sundays. The Purple Line runs on weekdays from about 06:40 to 21:05, provides only an afternoon service from 13:25 on Saturdays, and does not run on Sundays. The Orange Line runs on weekdays only, from about 07:40 to 20:45, with no service on Saturdays or Sundays. The Yellow Line airport branch runs on weekdays from about 07:20 until just after 21:00, roughly every twelve minutes during the day. Because these patterns change with each revision, confirm the line-specific official timetable before an early, late, weekend or airport trip.

A May 2026 Ministry release described Blue’s existing operating basis as about five minutes while presenting 2.5 minutes as an upgrade target. This does not guarantee a five-minute interval all day, and it must not be applied to Green, Purple, Orange or Yellow.

Current information does not support a single network-wide closing time or an all-line night-service rule. Plan around the final train shown for the chosen corridor and date rather than assuming that a late Blue service also exists on another line.

The Kolkata Metro began on 24 October 1984 with a 3.4 km service from Esplanade to Bhowanipore, now Netaji Bhavan. It remains India’s oldest metro network, while the Green corridor added a modern cross-river connection between Howrah and the eastern side of the city.

The completed Green route now runs from Howrah Maidan to Salt Lake Sector V. Its former central gap closed when passenger service began between Sealdah and Esplanade in August 2025, so that missing link must not appear as a future project on an updated Kolkata Metro map.

Kolkata Metro expansion plans

The Purple extension from Majerhat toward Esplanade remains under construction. A tunnel breakthrough at Victoria on 10 July 2026 was a construction milestone, not the opening of a station for Victoria Memorial visitors.

Orange is open only as far as Beleghata. The remaining 22.2 km toward Dum Dum Airport is not open, and the closure of a 62 m viaduct gap at Chingrighata in May 2026 marked engineering progress rather than a passenger-service launch.

Yellow runs to Jai Hind Bimanbandar, but it does not yet continue through the full planned northern corridor. Work toward Michael Nagar is in progress, while the New Barrackpore to Barasat section is held up by land acquisition and encroachment issues.

Green requires no future-gap caveat between Howrah Maidan and Salt Lake Sector V. Its full operation since August 2025 is one of the most important corrections when comparing a current plan with older diagrams.

Fun Fact: A January 2024 Ministry project note states that the Green Line spends about 45 seconds beneath the Hooghly River. Its twin bored tunnels include a 520-metre section directly below the river, about 350 metres downstream of Howrah Bridge. This is India’s first underwater metro transportation tunnel beneath a major river.

Use the Kolkata Metro route map with the open-line status table above so unfinished extensions are not mistaken for passenger routes.
