Magenta Line (Delhi Metro)

The Magenta Line (Line 8) is a metro rail line of the Delhi Metro, a rapid transit system in Delhi, India and the first driverless metro in India. The line, which runs across North, West and South Delhi and is mostly underground, spans 50.18 kilometers (31.18 mi) and consists of 33 metro stations: 17 are elevated and the rest are underground. Unlike the Airport Metro Express, this line directly serves Terminal 1 of the Indira Gandhi International Airport. Currently trains on this line run on two separate sections, i.e., Majlis Park - Deepali Chowk and Krishna Park Extension - Janakpuri West - Botanical Garden. Initially there was no direct service on the latter section but as of April 2026 every second train terminates at Krishna Park Extension.

The Janakpuri West metro station on the line contains India's tallest escalator with a vertical height of 15.6 meters (51 ft). The highest point on the Delhi Metro network is near the Haiderpur Badli Mor Metro station, where the line reaches a record-breaking height of 28.362 metres at Pier No. 340. This location surpasses the previous record of 23.6 meters at Dhaula Kuan on the Pink Line. The Magenta Line has interchanges with the Yellow Line at Hauz Khas and Haiderpur Badli Mor, with the Blue Line at Janakpuri West and Botanical Garden, and with the Violet Line at Kalkaji Mandir, and with the Pink Line at Majlis Park of the Delhi Metro network.

Shankar Vihar metro station is unique within the network as it is the only station where civilian movement is restricted by the military. Located within the Delhi Cantonment, it primarily serves defence personnel due to its position in the heart of the defence zone. The Hauz Khas metro station on this line is the deepest metro station in the network at a depth of 29 meters (95 ft).

For the first time in India, the construction of two parallel tunnels was successfully completed concurrently at the Dabri Mor–Janakpuri South station.
