DMRC Phase V: Magenta Line Set to Overtake Pink Line as Delhi’s Longest Corridor

Delhi Metro Magenta Line (Line 9) will become the longest line of the network with an approximate length of 89 kilometers (Noida Botanical Garden to Inderlok) after Phase V approvals. Having 65 stations and the largest number of interchanges and undergrounds, it will help to increase the connectivity on the Delhi-NCR. 

This was announced by the Delhi Metro Rail Corporation (DMRC) on February 11, 2026, as it entails complete driverless operation.

Which Extensions are the Longest at Magenta Line?

Phase V comprises an underground extension of Ramakrishna Ashram Marg (RKAM) to Indraprastha via Central Vista, which has nine new stations. 

Excluding a portion of 29-km Janakpuri West-RKAM that is part of Phase IV, the Inderlok-RKAM corridor will be fully integrated and the line will extend to 89 km, surpassing the 72 km of the Pink Line.

What is the Status of Magenta Line?

In service since 2018 (Botanical Garden-Janakpuri West, 37 km, 25 stations Phase IV extensions) (Phase IV extensions) such as Janakpuri West-RKAM (approaching a March 2026 opening) include underground tunnels up to 25.9m depth. 

It already crosses at Chirag Delhi ( Yellow ), Hauz Khas ( Yellow/Yel./Pink ) and others and it increases the number of ridership as a result of NCR expansion.

What are the Main Characteristics of the Widened Corridor?

The 89km line will have 65 stations (maximum interchange: 10+), and most of them will be underground at Central Vista to cause as little disturbance as possible. 

The CBTC signaling is fully driverless and therefore efficient. It is the first direct Metro to Central Vista (new parliament, offices) and thus there is less traffic congestion.

Influence on Delhi-NCR

It connects with Noida, South/Central Delhi, West Delhi (Pitampura), and North Delhi (Inderlok), and the Violet (to Ballabhgarh), Pink, Yellow, Blue lines. 

It has such benefits as shorter commutes (e.g., Botanical Garden-Inderlok in about 90 mins) and can support 40-lakh+ commutes daily, as well as reduce road congestion, such as the Ring Road. The prices of the property also increase around new stations.

Challenges and Timeline

The land acquisition delays (e.g. Keshopur) moved Janakpuri-RKAM by a year to 2026. The tunneling of TBM goes under old buildings, which is controlled digitally. 

Full Phase V work begins after sanction, with completion of 2027-28 during an investment of Rs 25,000+ crore.

The addition of 89 km to Magenta Line makes the Delhi Metro world-class, transforming the NCR mobility with the technology of driverless trains and Central Vista. 

It offers to generate low emissions, economic development, and urbanization, which is an example of an infra push of India.
