Delhi Metro Grey Line
Four stations and 4.98 km from Dwarka-Kakrola, on the Blue Line, to Nangli, Najafgarh and Dhansa Bus Stand.
About the Grey Line
On 20 October 2026 DMRC’s website showed the line as “Normal Service”. That is the only live information DMRC publishes; check it on the day you travel.
DMRC’s Line 9 has four stations, all in South West Delhi. It starts at Dwarka-Kakrola on the Blue Line, its only interchange, and runs through Nangli to Najafgarh and Dhansa Bus Stand. DMRC gives its length as 4.98 km. Dwarka-Kakrola and Nangli are elevated; Najafgarh and Dhansa Bus Stand are underground.
The Grey Line is built to standard gauge, while the Blue Line was built with wider track, and the two meet at no other point. Every journey beyond these four stations therefore involves a change at Dwarka-Kakrola, where the Grey Line platforms sit on the same level as the Blue Line ones.

| From the end of the line | First train (weekdays) | Last train (weekdays) |

Departure times from this station on a weekday, as DMRC’s journey planner gives them (checked on Tuesday 20 October 2026; the planner takes no date). DMRC does not publish separate Saturday, Sunday or holiday times for each station, and on special days it announces changes in advance. A last train after midnight belongs to the previous evening’s service. “Not published” means DMRC’s own answer was inconsistent (arrival before departure), so we leave it out.
Frequency by section
| Section | Weekday peak | Weekday off-peak | Saturday peak | Saturday off-peak | Sunday peak | Sunday off-peak |

Average interval between trains published by DMRC for each section (as on 31.08.2026). Peak hours are 08:00–12:00 and 17:00–21:00, the hours outside DMRC’s off-peak definition. Rapid Metro Gurugram figures come from its own page (peak 08:00–11:00 and 16:00–20:00 on weekdays; Sunday is one flat interval).
History
The first section, from Dwarka-Kakrola to Najafgarh with Nangli in between, opened to the public on 4 October 2019. The one-station extension to Dhansa Bus Stand was scheduled for December 2020, but the COVID-19 pandemic delayed construction and it was inaugurated on 18 September 2021.
At Dwarka-Kakrola the interchange was built with five platforms on one level: two for the Blue Line, two for the Grey Line and one that connects the Blue Line with Najafgarh depot. The Grey Line uses the same type of trains as the Pink and Magenta Lines, but its stations were built without platform screen doors.
Najafgarh station has an unusual plan. It was designed as a regular rectangle, but once work began on the ground some of the private land it needed could not be acquired, so DMRC built it on the land that was available. The result is a dumbbell-shaped station whose footprint narrows by a few metres in the middle.
How the service works
One service runs from end to end. DMRC gives an average interval of 7 min 30 s in the weekday peak and 12 minutes off-peak over the whole line. On weekdays the first trains leave Dwarka-Kakrola and Dhansa Bus Stand at 06:00 and the last at 23:00; counting the intermediate stations, trains run until 23:05. At Dwarka-Kakrola the connecting Blue Line trains are far more frequent, every 2 min 51 s in the weekday peak. Journey times between any two stations are on the route planner.
Frequently asked questions
No. The Grey Line is standard gauge and the Blue Line was built with wider track, so every journey between them means changing trains at Dwarka-Kakrola, where the platforms of the two lines are on the same level.
It was planned as a rectangle, but some private land could not be acquired once construction started. DMRC fitted the station into the land it had, so it narrows by a few metres in the middle.
The extension from Najafgarh was due in December 2020, but the COVID-19 pandemic delayed construction. It was inaugurated on 18 September 2021, almost two years after the Dwarka-Kakrola – Najafgarh section opened in October 2019.
