Pink Line (Delhi Metro)

The Pink Line (Line 7) is a metro rail line of the Delhi Metro, a rapid transit system in Delhi, India.^[1] It consists of 38 metro stations from Majlis Park to Shiv Vihar, both in North Delhi.

At 59.24 kilometres (36.81 mi), the Pink Line is the longest individual line in the Delhi Metro and in India, exceeding the length of the operational Blue Line (excluding its branch line). It is mostly elevated and covers Delhi in a Circle. The Pink Line is also known as the Ring Road Line, as the line passes mostly alongside the Ring Road in Delhi.

The Pink Line has interchanges with most of the operational lines of the network, such as the Red Line at Netaji Subhash Place & Welcome, Yellow Line at Azadpur & Dilli Haat - INA, Green Line at Punjabi Bagh West, Blue Line at Rajouri Garden, Mayur Vihar Phase-I, Anand Vihar & Karkarduma, Dhaula Kuan of Airport Express (Orange Line) at Durgabai Deshmukh South Campus, Violet Line at Lajpat Nagar, as well as with Hazrat Nizamuddin and Anand Vihar Terminal (Indian Railways / Namo Bharat) and the ISBTs at Anand Vihar and Sarai Kale Khan.

The Pink Line has the highest point of the Delhi Metro at Dhaula Kuan with a height of 23.6 metres (77 ft), passing over the Dhaula Kuan grade separator flyovers and the Airport Express Line.^[2] It also possesses the country's smallest metro station, Ashram, with a size of just 151.6 metres (497 ft) against the usual 265 metres (869 ft).^[3]: 93 The usual platform length for a six-coach train on this route is 140 metres (459 ft) but it has been reduced to 135 metres (443 ft) in the Ashram station.

As of September 2025, main services run between Majlis Park and Maujpur-Babarpur. The further route towards Shiv Vihar acts as a feeder line with separate services, for which passengers have to change platforms. This is because the line will be extended from Maujpur - Babarpur to Majlis Park via areas in North Delhi, effectively creating a circular metro which would be one of the world's longest circular railway lines. Once it happens, trains will run in anti-clockwise and clockwise directions in the main loop. Construction is complete, although full service trials on the whole circular route are being done since August 2025.^[4]

The line was initially put on table as a metro route that would run almost along the Delhi's busy Ring Road, on the lines of the existing Delhi Circular Railway. A route length of 59.24 kilometres (36.81 mi)^[5] was proposed from Majlis Park to Shiv Vihar, that would cut through all the existing lines at various interchanges as part of Phase 3's expansion plans. There are 38 stations in the Pink Line, out of which 26 are elevated and 12 are underground.

The line was opened in stages from 2018 to 2021. The first section on the Pink Line become operational from 14 March 2018 between Majlis Park to Durgabai Deshmukh South Campus, it was then extended to Lajpat Nagar on 6 August 2018. A separate section between Shiv Vihar to Trilokpuri-Sanjay Lake was opened on 31 October 2018 and the initial section was extended to Mayur Vihar Pocket I on 31 December 2018.

The section between Trilokpuri Sanjay Lake and Mayur Vihar Pocket I was not completed as construction of a 1.5 km (0.93 mi) viaduct began late due to land acquisition issues at Trilokpuri.^[6] This had rendered the Pink Line into two independent lines and forced DMRC to convert the Mayur Vihar Pocket-1 station into a terminating station with reversal facilities so that trains from Majlis Park would terminate there. On the eastern section, trains would run in separate loops - Shiv Vihar to Maujpur-Babarpur, Maujpur-Babarpur to IP Extension/Trilokpuri-Sanjay Lake. Every third train from Maujpur-Babarpur would move beyond IP Extension to Trilokpuri-Sanjay Lake as the latter has no reversal facilities and single line movement took place in that section. Both disjoint sections were finally bridged on 6 August 2021.^[7]

In December 2024, trial runs were initiated on the Phase 4 extension from Majlis Park to Jagatpur Village stations which were gradually done till Sonia Vihar and finally Maujpur-Babarpur by August 2025.

The stations of the Pink Line are:^[8]

Gokulpuri-Hindon Airport-Arthala Pink Line Extension: In September 2024, the DMRC proposed a branch of 13 km from Trans-Yamuna North-East Delhi (existing Gokulpuri metro station of Pink Line) to the west Ghaziabad (existing Arthala metro station of Red Line) via Hindon Airport connecting 2 existing Red Line metro stations with 10 new Pink Line stations namely Gol Chakkar, DLF, Shalimar Garden, Hindon Airport, Bhopura, Tulsi Niketan, Rajendra Nagar, New Karhaira Colony, Karhaira, and Loni Road Industrial Area.^[9]
