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).
There is a proposed extension which goes from Dhansa Bus Stand to Jhajjar City which would make the line around 43 kilometres.

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.[3]
