The Grey Line (Line 9) is a line of the Delhi Metro that connects Dwarka to Dhansa Bus Stand located in Najafgarh in the western part of Delhi, India. The total length of the line is 5.19 kilometers (3.22 mi).^[1] It is the shortest line on the entire network.

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 1,435 mm (4 ft 8+1⁄2 in) standard gauge tracks, while the Blue Line was built with wider bg

tracks.

The line uses the same rolling stock used on Pink and Magenta lines, although no Platform Screen Doors (PSDs) 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).^[2]
