The Grey Line (Line 9) is a line of the Delhi Metro that connects Dwarka to Najafgarh in the western part of Delhi, India. The line was opened to the public on 4 October 2019 at 5 PM in evening. A further extension to Dhansa Bus Stand is scheduled to open in December 2020.

The line has a single interchange to the rest of the Delhi Metro network at Dwarka station, connecting to the Blue Line. Grey Line uses standard gauge track, while the Blue Line was built with wider Indian gauge tracks.

The line uses the same rolling stock used on Pink and Magenta lines, although no Platform Screen Doors have been installed due to low ridership projections.

The Dwarka Station is the only station in the network to have five platforms on the same level (2 are for the Blue Line,2 for the grey line, and the third one connects the Blue Line with the Najafgarh Depot).

Najafgarh station was initially planned in the regular rectangle shape. However, when the construction work began on-ground, some of the private land could not be acquired for the project.

Due to this, Delhi metro had no other option but to plan the metro station with the land which was available to them. The dumbbell shaped station will be completed in such a way that the station area will shrink by a few metres in the middle.[2]

gollark: They have the same FP64 and FP32 performance.

gollark: We actually use MI250 GPUs anyway.
