Namma Metro Network: Lines Open, Under Construction and Planned
Namma Metro is now part of almost every property advertisement in Bangalore, but the lines are at very different stages. Three are open, two are being built and two more are approved or proposed. This guide sets out each line in October 2026, the localities it serves and how much weight a home buyer should give it.
The Network at a Glance
Namma Metro has 96.1 km of track and 83 stations in service, run by Bangalore Metro Rail Corporation Limited (BMRCL). The table lists every line by stage, and the sections below add the detail.

|---|---|---|---|
| Purple | Challaghatta to Whitefield (Kadugodi) | 43.49 km | Open |
| Green | Madavara to Silk Institute | 33.46 km | Open |
| Yellow | RV Road to Bommasandra | 19.15 km | Open |

| Orange and Magadi Road corridor (Phase 3) | JP Nagar 4th Phase to Kempapura, Hosahalli to Kadabagere | 44.65 km | Approved, at tender stage |
| Red (Phase 3A) | Hebbal to Sarjapura | 37.8 km | Awaiting central approval |
Lines That Are Open
Three lines carry passengers today. A home near one of their stations has a benefit that the buyer is able to test before paying.
Purple Line
The Purple Line runs east to west across the city, with 37 stations. It links Kengeri and Mysore Road with Vijayanagar, Majestic, MG Road, Indiranagar, KR Pura and Whitefield. The eastern stretch from KR Pura to Whitefield opened in March 2023 and changed the commute to the ITPL belt.
Green Line
The Green Line runs north to south, with 32 stations. From Madavara on Tumkur Road it passes Peenya, Yeshwanthpur, Rajajinagar and Malleshwaram, and meets the Purple Line at Majestic. It continues through Basavanagudi, Jayanagar and Banashankari to Kanakapura Road. It serves the older, settled residential parts of the city.
Yellow Line
The Yellow Line opened in August 2025, with 16 stations. It connects RV Road with BTM Layout, Central Silk Board, Bommanahalli, Hosa Road, Electronic City and Bommasandra. Passengers change to the Green Line at RV Road.
Lines Under Construction
Two lines are being built. Both have changed their opening targets more than once, so a buyer should plan the commute on what runs today.
Pink Line
The Pink Line will have 18 stations from Kalena Agrahara on Bannerghatta Road to Nagawara in the north. Its elevated section of 7.5 km and six stations, up to Tavarekere, is built and has completed its trials. Services will begin once the Commissioner of Metro Railway Safety clears the section.
The rest of the line is underground, through Dairy Circle, MG Road, Shivajinagar and Cantonment, and will open at a later stage. The Pink Line will meet the Yellow Line at Jayadeva Hospital and the Purple Line at MG Road. Homes on Bannerghatta Road gain first, and those near the underground stations gain later.
Blue Line
The Blue Line has 30 stations in two parts. The first runs 19.75 km along the Outer Ring Road from Central Silk Board to KR Pura, past Bellandur and Marathahalli. The second runs 38.44 km from KR Pura to the airport through Nagawara, Hebbal and Yelahanka.
BMRCL has moved the start of services on the Silk Board to KR Pura part into 2027, and the airport part will follow. The line will connect with the Yellow Line at Central Silk Board and the Purple Line at KR Pura. Once the Pink and Blue lines are fully open, the network will reach about 175 km.
Lines Approved or Proposed
Two further phases exist on paper and in tenders. They belong in a long-term view of a locality and deserve little weight in the price paid today.
Phase 3: Orange Line and the Magadi Road Corridor
Phase 3 covers 44.65 km and 31 stations, and the Union Cabinet approved it on 16 August 2024. The Orange Line of 32.15 km follows the western Outer Ring Road from JP Nagar 4th Phase to Kempapura, past Mysore Road and Sumanahalli Cross. A second corridor of 12.50 km runs along Magadi Road from Hosahalli to Kadabagere.
The state has decided to build Phase 3 as a double-decker, with a road flyover below the metro track, at an added cost of Rs. 9,700 crore. BMRCL issued the first civil tenders in 2026, and the completion target has moved from 2030 to 2031. Major construction along the alignment will bring several years of road diversions before any train runs.
Phase 3A: Red Line
The Red Line is a proposed corridor from Hebbal to Sarjapura, 37.8 km long in the plan revised in February 2026. Its route passes through the city centre, Dairy Circle, Koramangala and Agara before following Sarjapur Road. The Karnataka cabinet approved it on 6 December 2024, and it is awaiting the approval of the central government.
Cost and design are still under review, so the opening year remains open. For Sarjapur Road, which has no metro station today, the Red Line is a plan and should be read as one.
How Buyers Should Weigh Each Stage
The stage of a line matters more than its length or cost. A simple rule keeps the metro in proportion when comparing two homes.
- Open line: count it fully, after walking from the home to the station at the hour of the commute
- Line under construction: count it as a later benefit, and expect dust, diversions and a possible delay until then
- Approved line at tender stage: treat it as a long-term plus that is many years away
- Proposed line: leave it out of the price
Distance decides the rest. A station within a ten-minute walk changes daily life, while one that needs an auto or a feeder bus helps far less. Interchange stations such as Majestic, RV Road and KR Pura give access to two lines, which widens the choice of workplaces.
Checks Before Paying for Metro Access
Advertisements often show a station close to the project without stating the line or its stage. Five checks settle the matter.
- Name the line and the exact station, and confirm both on the BMRCL route map.
- Confirm whether that station is open, under construction or only planned.
- Walk the route from the gate to the station entrance, and note the crossings and footpaths.
- Ask whether the road in front of the project is on a metro alignment where land is still to be acquired.
- Compare the price with a similar home further from the station, to see what the metro is adding.
The home should also work without the line that is still to come. We are glad to share which stations are open near any project on our pages.
