Pink Line becomes Delhi Metro’s longest line with 12 interchanges

Post by : Shivani

Delhi’s Pink Line is on the verge of taking a landmark position in the Delhi Metro network. Once the Majlis Park–Maujpur extension opens later this month, the Pink Line will stretch to 71.6 kilometres and include 12 interchange stations, making it the longest corridor in the system. 

This expansion is part of Phase IV of DMRC’s (Delhi Metro Rail Corporation’s) expansion plan, and will allow the Pink Line not only to serve a larger geographic area but also to function as a circular route. 

At present, there are 29 interchange stations across the entire Delhi Metro network. The Pink Line, which currently has 10 interchange stations, will add Maujpur and Majlis Park as new interchanges when the upcoming stretch becomes operational. 
 

Some of its existing interchange stations are Azadpur, Punjabi Bagh West, Netaji Subhas Place, Rajouri Garden, Lajpat Nagar, Dilli Haat‑INA, Mayur Vihar I, Anand Vihar ISBT, Karkardooma, and Welcome. With the new stretch, passengers will be able to switch lines even more flexibly. 

The Pink Line was originally inaugurated in several segments. The first section—Majlis Park to Durgabai Deshmukh South Campus—opened in March 2018. Subsequently, other parts followed, including two disconnected segments (Majlis Park‑Mayur Vihar Pocket 1, and Shiv Vihar‑Trilokpuri) due to land acquisition issues in Trilokpuri. The final gap‑filling 0.85 km stretch (Trilokpuri‑Sanjay Lake to Mayur Vihar Pocket 1) was inaugurated in August 2021.

With the new Majlis Park–Maujpur segment, the Pink Line will become the first DMRC line to create a circular route, enhancing connectivity across Delhi significantly. 

In comparison:

• The Blue Line has 10 interchange stations.

• The Yellow Line has 8 interchange stations. 

• The Red Line, which runs from Rithala to Shaheed Sthal, has 4 interchange stations.

• The shortest line, the Grey Line (Dwarka to Dhansa Bus Stand, about 5.5 km), has just one interchange station.

Under Phase IV, DMRC plans to add even more interchange stations through new corridors and extensions. For instance:

• The Golden Line (Tughlaqabad–Aerocity) will have 7 interchange stations.

• The Magenta Line extension from Janakpuri West to RK Ashram will add 3 new interchanges.

• Other extensions, such as Lajpat Nagar‑Saket G Block, Inderlok‑Indraprastha, and Rithala‑Narela‑Kundli are also in the works. 

All of these will substantially grow the network, both in reach and in ease of travel for commuters.

For Delhi’s commuters, the Pink Line’s 12 interchange stations mean greater flexibility. Passengers will be able to move across different metro lines without needing to exit stations, reducing travel times and simplifying transfers. Interchange stations are especially useful for people whose journeys cross from one side of the city to another and need to switch lines. DMRC’s own analysis for October 2023‑March 2024 showed that a large share of metro users are transferring between lines rather than staying on a single line. 

This expansion doesn’t just represent physical distance—it marks a shift in connectivity and metro network design. The Pink Line’s transformation into the longest and the first circular corridor is a step change in how metro transit integrates across Delhi. More areas will be linked, more commuters will benefit, and the transit network as a whole becomes more efficient.
