Delhi Metro’s Green – Pink Line Interchange Takes Shape

Workers from Som Projects Pvt. Ltd. have started erecting the first few steel piers near Punjabi Bagh West Station to form the Delhi Metro’s missing Green Line (Line-5) – Pink Line (Line-7) interchange as part of package CC-136 of the Delhi Metro’s 162 km Phase 3 project.

This project to build an interchange aims to rectify a major design oversight during the 124 km Phase 2 project’s construction between 2006-2010 as the Delhi Metro Rail Corporation (DMRC), for unknown reasons, did not construct a station on the Green Line abutting the Ring Road. During Phase 3’s construction, when the Pink Line was being built along this road, the DMRC initially planned to build a 820m foot overbridge to connect the new Pink Line’s Punjabi Bagh West Station with the Green Line’s Shivaji Park Station, but dropped it for a better long-term solution.

To fix this, Som Projects is now constructing or retrofitting an entirely new ‘halt’ station with platforms on the operational viaduct of the Green Line, without a concourse area, to allow passengers to board and de-board. From there, riders will then need to go down one level and take a 230m elevated walkway to the reach the concourse area of the Punjabi Bagh West Station of the Pink Line.

LKT Engineering was awarded this project’s Detailed Design Consultant (DDC) in October 2019 and Bridgecon Infa Consultants was awarded its Proof Consultant contract in January 2020.

Here are some snaps sent by a follower shot next to the Pink Line’s Punjabi Bagh West Station shown in the bottom right corner of the above graphic –

Earlier this week, I tweeted an image showing the other side of Rohtak Road (NH9) where a pile cage, to support the new halt station’s platform level, was spotted getting lowered into the ground. Looking at it again, this possibly could also be a rebar cage, that still needs to be properly tied up, for the first pier.

Som Projects was awarded this project’s Rs. 46.77 crore 13-month contract in August 2019, so in the ideal world civil work should have been completed by now, but clearly hasn’t. I’m unaware of the new deadline they’re chasing but am glad to see things moving along.

    Apparently isn’t such poor planning more evident also in Mumbai Metro, particularly when all new lines are being built simultaneously? Cannot fathom WHY??

    • Sayed says:

      Yess, even i believe they could have planned a better layout than what we are seeing at the intersections in Mumbai

    • Himanshu Doria says:

      What poor planning ? Go there and you would find a Railway Yard, A Jhuggi Colony and several houses and structures that would had led DMRC stuck into the litigation limbo if they had tried to remove it. Phase 3 was one of the most challenging projects executed in Delhi with several land acquisition issues. Even now trilokpuri issue is not fully resolved with some of the affected families trying to stall it in hopes of fleecing more compensation. Half of land for Kalindi Kunj depot is still under illegal encroachment despite DMRC having won the case because somehow the encroachers have managed to obtain stay and DMRC was forced to construct Elevated stabling lines near Jasola vihar station.

      IMHO, this is much better resolution.

        DMRC is one of the best executed project. Lot of critical issues were dealt with good planning and engineering. If there are problems it’s due to litigation. Airport line was efficiently taken over by DMRC and well managed. When Reliance could not do it.

    Well, there had been huge mistakes. Eg: no inter connectivity between blue line and airport express line. They expect airport bound travelers of the blue line, having atleast 2 luggage units, to be getting off at Rajiv chowk and either walking all the way to Shivaji stadium (in the extreme weather of Delhi) or hiring another means of transport to reach there (if available for this small but significant distance)

    The construction work at trilok puri (Pink line) has been started. there are no images released yet. you are requested to put a image of this site.
