Delhi Metro’s Lajpat Nagar – Saket & Inderlok – Indraprastha Lines Approved by Central Govt

The Central Government’s Cabinet today officially approved the Detailed Project Report (DPR) of two key lines of the Delhi Metro Phase 4 project at an estimated construction cost of Rs. 8,399 crore.

These lines totaling 20.76 km include 12.377 km Inderlok – Indraprastha extension of the operational Green Line (Mundka – Brigadier Hoshiyar Singh), and 8.385 km Lajpat Nagar – Saket G Block line which might operate as a spur of the under construction Golden Line (Aerocity – Tughlaklabad).

Both lines by the Delhi Metro Rail Corporation (DMRC) are located in the core of the city and will further densify the network.

Inderlok – Indraprastha

This 12.377 km mostly-underground extension of the Green Line (Line-5) with 10 stations will consist of a 11.349 km underground route and 1.028 km elevated route.

It involves part demolition and abandonment of the line’s viaduct and station box at Inderlok Station built in Delhi Metro’s Phase 2 project. It will be interesting to see how the DMRC navigates this and orchestrates its construction with minimal interruption to services.

The DMRC has mapped out Inderlok – Indraprashta’s exact alignment over here.

This extension will take the Green Line right into Old Delhi or Purani Dilli (Shahjahanabad) and provide an interchange with the Red Line (Inderlok Station), Magenta Line (under construction Nabi Karim Station) Yellow & Airport Express lines (New Delhi Railway Station), Violet Line (Delhi Gate Station), and Blue Line (Indraprastha Station).

Lajpat Nagar – Saket G Block

This 8.385 km elevated line with 8 stations might operate as a spur of the Golden Line. This extension’s alignment has changed multiple times over the years, and the most current alignment can be viewed over here.

It will consist of 8 elevated stations at Saket-G Block, Pushp Vihar, Saket District Court, Pushpa Bhawan, Chirag Dilli (interchange with Magenta Line) Greater Kailash-1, Andrews Ganj and Lajpat Nagar.

Detailed designs for both new lines’ construction have long been ready, so with this key approval received tender notices for construction of the elevated portions should be around the corner.

The DMRC had assigned the following consortia as the Detailed Design Consultant (DDC) for each line back in 2019:

  • Inderlok – Indraprastha: Ayesa Ingeniera y Arquitectura SAU – Fountainhead – Ayesa India Pvt. Ltd. (Contract DCDD-01-R)
  • Saket G Block – Lajpat Nagar: AECOM Singapore – Tandon Consultants – AECOM India Pvt Ltd. (Contract DCDD-02)

A list of all Delhi Metro Phase 4 packages, their contractors and status can be viewed here.

It remains to be seen if Japan International Cooperation Agency (JICA) will fund these lines’ development for underground tunneling and systems procurement like it signed and committed to do in 2021 for Phase 4’s 65.1 km Priority Corridors.

With this development, a total of 85.86 km of new lines have been approved under Delhi Metro’s Phase 4 of which 65.1 km are under construction (Pink, Magenta & Golden). The only line pending approval from the original list of 103 km of corridors finalized in 2015 is the Red Line’s 21.73 km north-west extension from Rithala to Narela.

    These lines were long awaited. Good to see the approval.

    But I think the Indralok- Indraprastha line should have been extended till Hazrat Nizamuddin. It would have multiple benefits.
    1- Metro connectivity between two major railway station of Delhi
    2- Connectivity to Sarai kale khan RRTS (which is going to be hub of RRTS corridor in future)
    3- Connection to Delhi spur of Delhi- Mumbai expressway.

    What is your opinion on this?

    • Roshan Raj Singh says:

      I totally agree, I envisioned the same in my fantasy map for the Delhi metro here-

      In-fact, I want Green line to be extended all the way to Lajpat Nagar and to subsume Lajpat Nagar – Saket G block corridor into it. Thus providing the one seat ride from Saket all the way till Bahadurgarh, if they can somehow directly connect that resulting Mega Green Line to with Yellow Line by providing interchange at Saket, then it will become ultimate city connector.

      This might finally push DMRC to allot 6 coach trains on the Green Line.

      • Kartik says:

        I have also been asking for extension of green line all the way to Sarai kale khan for years now. Hopefully someone higher up reads this and thinks about it.

      • Rambir says:

        Hi, I would like to have a detailed discussion over this map, as I also share the same imagination of future lines etc

    • Aditya says:

      Much needed. If it is extended to Hazrat Nizamuddin them three main railway stations of Delhi will get connected on a single line being Sarai Rohilla, NDLS and NZM.
      Also I want that airport express line be extended from NDLS to Kashmere Gate and Golden line be extended from Aerocity to T1.
      These small extensions will save so mcuh travel time.

    • NAVEEN BANSAL says:

      I want golden/silver line to be extended to kalindi kunj station.

    • Kartik says:

      Along with this, I would want the silver/golden line to be extended to connect both the terminals of the airport and then go on to get merged with the grey line. That way grey line can finally make some sense

    • Rahul says:

      This is an obvious observation that came to our mind, I wonder why they didn’t think about it, is it because of already so much construction there, new lines can’t be built there ? But I think it’s difficult, but not impossible, you just have to agree to build there.

    • Anish Sinha says:

      I also want Green Line to be extended from Kirti Nagar to Dwarka to improve connectivity in South Delhi

  2. Rishav says:

    What do you think the completion date will be for these? Heard it’s 2029 now.

  3. Shashi says:

    Any idea why Bangalore metro phase 3 is not approved y’day?

  4. Yash tyagi says:

    Expected Completion date for these new corridors?
    DMRC along with Delhi Govt. are already struggling to complete already started three phase 4 corridors. They cannot be completed before 2027 (especially the Golden Line).
    Now, these Entire New Streches.
    So, seeing the speed of construction of DMRC It’s obvious these new corridors will take another 4 years, that means around 2030-31 only, they will be functional.
    What do u say?

    • Uday says:

      You mean kejruddin chappal chap government right?

      • Rishav says:

        Since when central govt became kejri govt?

      • Yash tyagi says:

        Yes Of course.
        There’s a saying ‘one fish pollutes the whole pond’. Same happened with Dmrc as soon as Kejriwal came into power. All the projects delayed. Like Phase 3, which was scheduled to be completed in 2016, got completed in 2021.
        So, Expect the same this time also.
        In phase 4, PM has laid foundation to these 3 under construction corridors back in 2019. Even after 5 years, not even 50% work is done.
        Today PM laid foundation for another 2 corridors but Of no use until the present delhi Govt. Is in power.
        All he can do is introduce Buses and Buses and buses and make the roads more congested.

  5. Mridul Yadav says:

    What is the present status of all tunneling activities of delhi metro phase 4?

  6. Chinmay says:

    Any way for Delhi AAP govt. to stall this project?

  7. Anish Sinha says:

    But how will they gonna increase the Green Line of the Delhi Metro from Inderlok.Not possible at all.Since the Green Line of the Delhi Metro meets the Red Line of the Delhi Metro perpendicularly here, unlike all the other interchange stations of the Delhi Metro.Thus This design choice ended the possibility of extending the line in the future (in this direction).How is it possible???????
