Pink Line or Line 7 was the first line to be inaugurated as part of Delhi Metro Phase III development. At 58.5 km, it is the longest line on the system; however, the entire line is not yet operational. The viaduct between Trilokpuri–Sanjay Lake and Mayur Vihar Pocket 1 has not been constructed, so the line works as two separate sections — Shiv Vihar to Trilokpuri–Sanjay Lake and Majlis Park to Mayur Vihar Pocket 1 — with a total of 38 stations. It is one of the only three lines on the system to have platform screen doors at all stations, communication-based train control (CBTC) technology as well as facilities for driverless train operation. The line has six-coach trains that run at a maximum sped of 80 km/h on 1435 mm (standard gauge) tracks and 25 kV AC via overhead wires. Pink Line runs through the city in a circle, mostly along the Inner Ring Road.

Further Extension of Pink Line
Under Phase IV, Pink Line is to be extended from Maujpur–Babarpur to Majlis Park. This way, those who have to commute between the two stations, will not have to travel on the entire line and Delhi in a virtual circle; they can simply take the train across the Yamuna River to reach their destination.
