Bangalore Metro Phase 3, 3A & Suburban Rail: 2026 Status

Every figure on this page was checked against its source on 6 August 2026. Infrastructure dates in Bangalore move, so that date tells you how much to trust what follows.

Bangalore has 96.10 km of metro in passenger service across 83 stations. It has 148.17 km of suburban railway sanctioned, funded and under contract, on which the operator's most recent annual report records 16.5% physical progress by value and, of route kilometres delivered, "Physical Progress in km: Nil". Between those two numbers sits most of what a buyer is being sold, and almost none of it has a date you can rely on.

This is a status page, not a route map. It sets out what is running, what is sanctioned, what is only proposed, and how many times each promise has already moved. Which areas already have a station is a separate question, answered area by area in Best Areas to Live in Bangalore 2026.

What is running in Bangalore today

Three lines. Nothing has opened since the Yellow Line entered revenue service on 11 August 2025.

Two of those rows are better sourced than the others, and you should know which. The total is BMRCL's own, from its Annual Report 2024-25: the network "increased from 76.95 KMs to 96.10 KMs comprising of 83 Stations". The Yellow Line row is also BMRCL's, which "dedicated 19.15 KMs with 16 Stations". But BMRCL publishes no length or station count for the Purple or Green Line anywhere in that report. The 43.49 km / 37 and 33.46 km / 32 figures come from Wikipedia's line articles, retrieved 6 August 2026, and other trackers give 42.17 km and 33.03 km. We use the Wikipedia figures because they are the only ones that reconcile to BMRCL's own total: 37 + 32 + 16 = 85, less Majestic and RV Road counted twice as interchanges, gives 83.

Two dates worth separating, because most pages conflate them. The Yellow Line was dedicated on 10 August 2025 and, in BMRCL's words, "The Revenue Services commenced from 11th August, 2025". Its service is still thickening: the 15th trainset arrived by 28 July 2026 with 13 commissioned, running a seven-minute peak headway against the 25-minute headway and three trains it opened with.

On ridership, BMRCL's own newsletter records 2,74,93,833 passengers in April 2026, an average of about 9.16 lakh a day, with a single-day maximum of 10,36,073 on 30 April 2026. It publishes those figures system-wide and gives no split by line, so anyone quoting per-line ridership for the Purple or Green Line is inventing it.

Namma Metro Phase 3: what the Union Cabinet approved

The Union Cabinet approved Phase 3 on 16 August 2024: two elevated corridors, 44.65 km, 31 stations, ₹15,611 crore, with an operational target of 2029. Corridor 1 runs JP Nagar 4th Phase to Kempapura along the Outer Ring Road west, 32.15 km and 22 stations. Corridor 2 runs Hosahalli to Kadabagere along Magadi Road, 12.50 km and 9 stations. The Prime Minister laid the foundation stone on 10 August 2025, the same day he inaugurated the Yellow Line.

Financial closure came on 24 March 2026, when the Government of India and JICA signed a ₹6,775 crore loan.

Civil work has not started. Bids invited in January 2026 are on hold after the Centre objected to the state's proposal for a 37.12 km double-decker viaduct costing an additional ₹9,692.33 crore. As at 6 August 2026 that dispute is unresolved, and Deccan Herald reported on 5 August 2026 that BMRCL was still working to start civil work on the Orange Line.

Phase 3 touches JP Nagar, Hebbal, Rajajinagar and the west Bangalore belt toward Mysore Road.

Phase 3A: approved by the state, not sanctioned by the Centre

This is the line sold hardest along Sarjapur Road, and it is the one furthest from being built.

The Karnataka Cabinet cleared it in December 2024. BMRCL's Annual Report describes the original detailed project report as "36.59 KMs of metro line from Hebbal to Sarjapur along the Sarjapur road with twenty-eight (28) elevated/underground stations at an estimated completion cost of ₹28,405 Crore", approved by the state in January 2025 and then sent to Delhi.

Delhi sent it back. On 23 May 2025 the Ministry of Housing and Urban Affairs said Karnataka had submitted "about 37 Km at the estimated cost of about Rs 28,400 crore", that "the cost estimate of phase-3 A network needs to be examined by expert agency", and that the project "will be taken up for sanction by Central Government, once reply is received from Government of Karnataka".

BMRCL had the consultancy Systra review it for cost. A revised DPR went in during February 2026 and reached the Centre in April 2026: 37.8 km, 1.215 km longer overall with 160 m less underground, at ₹25,999 crore. Underground stations shrank from 200×27 m to 170×21.5 m. The line now needs 35 trains rather than 30. And the opening estimate moved to April 2033.

Read that last figure carefully. April 2033 is the revised report's own estimate for a line the Union government has not sanctioned. There is no PIB release after 23 May 2025.

Phase 3A would serve Sarjapur Road, Koramangala, HSR Layout and Hebbal.

Blue Line and Pink Line opening dates: every target Namma Metro has missed

The Pink Line and the Blue Line are being built now. Here is the commitment ledger: every publicly recorded target for each corridor, in order, with a name attached to it.

Five recorded targets for one 7.5 km stretch of the Pink Line, three more for the underground section behind it, and neither has opened. That is not a claim that the metro will not come. It is a measurement of how much to discount the date you are given.

The Pink Line's elevated section was held up by signalling validation: an RDSO speed certificate, then an Independent Safety Assessment, then the statutory CMRS inspection, in that order. Civil work was 98.07% complete in April 2026, with track laying at 92.55%. When it opens, the network goes from 96.10 km to about 103.6 km, on BMRCL's own total plus the 7.5 km of this stretch.

On the Blue Line, the first train reached Baiyappanahalli depot on 4 June 2026 and BMRCL officials said full trial runs were "many more months" away because the track was not ready. The line is 58.19 km and 30 stations, sanctioned on 20 April 2021 at ₹14,788.101 crore, later enhanced to ₹15,131.23 crore. Physical progress was 53.00% at 31 July 2025.

One more thing worth knowing when you read a target: BMRCL has had three managing directors since January 2024, the most recent appointed on 5 August 2026.

The Blue Line serves HSR Layout, Bellandur, Marathahalli, KR Puram, Hebbal, Thanisandra, Yelahanka and Devanahalli. The Pink Line serves Bannerghatta Road, JP Nagar, BTM Layout and Nagawara.

How to read a metro promise: the twelve rungs from proposal to platform

"Approved" is doing an enormous amount of work in Bangalore property copy, and it means at least four different things. Here is the actual ladder, and where each corridor stands on it.

The rungs, in order: feasibility study → detailed project report → state cabinet approval → Union government sanction → financial closure → tender award → foundation stone → civil works → rolling stock delivered → trial runs → CMRS safety clearance → revenue service.

That is the order the rungs are supposed to come in. Bangalore does not always take them in order, and the exception is instructive: a foundation stone is a political event rather than an engineering one, and it has twice been laid before the contract to build was awarded. Phase 3's stone went down on 10 August 2025, with civil bids still on hold a year later, and the suburban project's on 20 June 2022, with the Corridor 2 civil contract awarded on 26 August 2022. Treat a foundation stone as evidence of intent, not of work.

Dates below are as the source itself gives them. "FY2024-25" is the financial year April 2024 to March 2025, the period BMRCL's and K-RIDE's annual reports cover.

Two rungs matter more than the others. Union sanction is where a state announcement becomes a funded national project, and Phase 3A has not cleared it. CMRS clearance is the last thing between a finished line and a running one, and it is why the Pink Line has slipped five times while looking 98% built.

Bengaluru Suburban Railway: four corridors, and what has been built

The suburban project is sanctioned, funded by two European development banks, and has laid no track.

Lengths and the total are from K-RIDE's own 24th Annual Report. The corridor percentages are from the Karnataka Economic Survey 2025-26. Every one of them carries the date it was measured, because the project has no current figure.

The timeline is the story. Indian Railways sanctioned the project on 21 October 2020 at ₹15,767 crore. The Prime Minister laid the foundation stone on 20 June 2022, in K-RIDE's words, "with an assurance to complete the project in 40 months", which fell due in October 2025. K-RIDE's 24th Annual Report, for the year ended 31 March 2025 and signed on 20 December 2025, two months after that deadline fell, states in full: "Physical Progress in km: Nil." The report puts no date on that line itself; the companion figure in the same section is 16.5% physical progress as on 30 April 2025.

What has happened since: L&T terminated both civil contracts on 28 July 2025, claiming ₹505 crore, after being given only "12.83 km or 49.44% of the workfront… in 'unworkable fragmented stretches'". Replacement Corridor 2 packages were awarded in April 2026; one package went to tender for a third time in May 2026. The rolling-stock PPP tender failed and a work order went to Integral Coach Factory, Chennai, on 6 May 2026 for 153 coaches at ₹1,513.75 crore. The revised cost is ₹23,103 crore against ₹15,767 crore sanctioned.

Current targets, from K-RIDE's managing director Lakshman Singh in January 2026: first prototype train November 2027, Corridor 2 open December 2028, Corridor 4 in 2029, Corridors 1 and 3 by March 2030. The Union Cabinet had still not approved the rolling-stock cost-sharing as at June 2026.

Corridor 1 runs through Yelahanka, Devanahalli, Yeshwanthpur and Malleshwaram. Corridor 4 runs through Bommasandra, Bellandur, Panathur, Hennur, Thanisandra, Jakkur and Yelahanka.

The trains that already run: which Bangalore areas have a railway station today

The suburban project is years away. Indian Railways, meanwhile, already runs MEMU and passenger services through dozens of stations and halts across Bengaluru and the districts around it.

A station inside the area: Hoodi, Kengeri, Whitefield and Kadugodi, Panathur, Frazer Town, Yelahanka, Hebbal, Malleshwaram, Yeshwanthpur, Devanahalli, Rajarajeshwari Nagar.

A station on the edge, a short walk or auto away: Mysore Road, Tumkur Road, Chandapura, Sahakar Nagar, Vijayanagar, Rajajinagar.

A station within a short auto ride: Horamavu, Marathahalli, Indiranagar, KR Puram, Bommasandra, Bellandur, Vidyaranyapura.

And the finding that matters most: South Bengaluru inside the Outer Ring Road has no railway station at all, and none of the four suburban corridors gives it one. Not Jayanagar, not JP Nagar, not BTM Layout, not Bannerghatta Road, not Kanakapura Road, not Koramangala, not HSR Layout. For that whole belt, rail means metro or it means nothing.

Two caveats. A station existing is not a service existing: several of those are halts with sparse stopping patterns, and no official current station-by-station service list is published. And the service is thin enough that a single platform rebuild removes it. South Western Railway cancelled MEMU stoppages at Channasandra through 31 August 2026 for works on Platform 1. One more limit on the grouping above: we rank each area from a single geocoded centre point, in a straight line rather than by road, so for long road belts (Tumkur Road, Mysore Road, Bannerghatta Road, Kanakapura Road, Sarjapur Road) the answer depends on which end of the road you are standing at.

The genuine near-term unlock is not the suburban project but doubling on existing track. Baiyappanahalli to Hosur was "88% financially and 90% physically completed, with commissioning expected by February 2027", and Yeshwantpur to Channasandra was at 45% financial and 52% physical progress, targeted for March 2027, as on 31 December 2025.

How to check a metro promise against the project you are looking at

1. Find out which rung the line is actually on. "Approved" means at least four different things in Bangalore property copy. The ladder runs: feasibility study, detailed project report, state cabinet approval, Union government sanction, financial closure, tender award, foundation stone, civil works, rolling stock delivered, trial runs, CMRS safety clearance, revenue service. A corridor at state cabinet approval, like Phase 3A, is at rung three of twelve. A corridor at trial runs, like the Pink Line's elevated section, is at rung ten and can still slip for a year.
2. Ask who gave the date, and when they gave it. Every future date on a Bangalore metro corridor is somebody's target. The Pink Line's 7.5 km elevated stretch has had five recorded targets: March 2026, May 2026, 15 August 2026, late August or early September, and now September 2026. The Blue Line's Silk Board to KR Puram section was September 2026 in BMRCL's own annual report, December 2026 when the Deputy Chief Minister said so on 5 December 2025, and early 2027 by 5 August 2026. A date without a name and a date attached to it is not information.
3. Check whether the Union government has sanctioned it. State cabinet approval and Union sanction are different rungs and only one releases central funding. Phase 3 cleared the Union Cabinet on 16 August 2024 and reached financial closure with a JICA loan on 24 March 2026. Phase 3A cleared the Karnataka Cabinet in December 2024 and, as at the Housing and Urban Affairs Ministry's last public statement on 23 May 2025, had not been sanctioned by the Centre.
4. Separate an inauguration from a service start. The Yellow Line was dedicated on 10 August 2025 and, in BMRCL's own words, "The Revenue Services commenced from 11th August, 2025". Both dates are widely quoted as the opening. When a project page tells you a line is operational, check whether it means trains are carrying passengers or a ribbon has been cut.
5. Check what already runs, not only what is planned. Indian Railways runs MEMU and passenger services through dozens of stations and halts across Bengaluru and the districts around it today, and several localities have a working railway station while waiting for a metro. Equally, South Bengaluru inside the Outer Ring Road has no railway station at all and none of the four suburban corridors gives it one, so for that whole belt rail means metro or it means nothing.
6. Discount any price claim attached to a line. No research house publishes a metro price premium for Bangalore. The figures in circulation (15 to 25% within 1 to 2 km, 20 to 30%, "consistently high" within 1 to 4 km) come from builders' own marketing, carry no citation and do not agree on the radius. Treat a premium quoted alongside an unbuilt line as a sales argument, not a measurement.
7. Re-check before you sign, because this decays fast. Every corridor date in this post has moved at least once, and the Pink Line's elevated section five times. Before committing, re-check the three things most likely to have moved: whether the Pink Line's elevated section opened, whether the Centre sanctioned Phase 3A, and whether Phase 3 civil work started. BMRCL's annual report and monthly newsletter, and K-RIDE's annual report, are the primary sources and are all publicly downloadable.

Where the official sources disagree

Every page you will read on this subject picks one number. Here are the ones that are genuinely contested, and what we use.

What we could not verify

• There is no sourceable metro price premium for Bangalore. The figures in circulation (15 to 25% within 1 to 2 km, 20 to 30%, "consistently high" within 1 to 4 km) come from three builders' own marketing, carry no citation, and do not agree on the radius. We publish no premium, no appreciation figure and no yield for metro proximity, here or anywhere.
• Phase 3A's current station count is unknown. BMRCL gives 28 for the original DPR. The February 2026 revision removed a station without publishing a new total. We do not publish 27 by subtraction.
• No BMRCL operational data after May 2026. The audited report covers the 2024-25 financial year, April 2024 to March 2025; the newsletter runs to Issue 14, May 2026. The ridership API returns only the most recent single day, so no time series can be built.
• No current suburban progress percentage. 16.5% as on 30 April 2025, and 30% / 12% for two corridors as on 31 December 2025. Nothing for mid-2026.
• No Union Cabinet press release for the suburban sanction. The nearest primary is K-RIDE's own statement that it was "sanctioned by Govt of India through Ministry of Railways on 21.10.2020".
• The suburban station lists are 2019 planning documents, not the sanctioned scheme. Some names have since changed.
• No Phase 4 exists as an approved programme. Four feasibility studies, awarded 9 July 2024, and nothing sanctioned by either government.
• The railway-station grouping is our own working, from OpenStreetMap data retrieved on 6 August 2026, ranked from a single centre point per area in a straight line. It is not a published list, and we give no total because the answer depends entirely on where you draw the city boundary.

What could have changed since we published

Three things are most likely to have moved, in this order: whether the Pink Line's elevated section opened in September 2026; whether the Centre sanctioned Phase 3A; and whether Phase 3 civil work started once the double-decker dispute resolved. If you are reading this well after 6 August 2026, check those three first.

Every future date on this page is somebody's target, not a date. The commitment ledger above exists to show you how those have behaved.

If you want a specific project checked against what is built rather than what is on the brochure, tell us which line you are betting on and we will do that.
