TBM Makes 2nd Breakthrough at Delhi Metro’s RKP Mid-Shaft
I tweeted about this development right after it happened, but waited to post until snaps were available because who doesn’t love pictures?
On this past Saturday afternoon, the THI-2 Tunnel Boring Machine deployed by the L&T-SUCG JV for package CC-27 of Delhi Metro’s Phase 3 project made a successful breakthrough at the 38.235 km Magenta Line’s RK Puram mid-shaft! This TBM was commissioned from the Vasant Vihar station in September 2015 and traveled roughly 950 meters (built 659 rings) to reach the mid-shaft which has been constructed exclusively for the line’s up-line tunnel.
The mid-shaft is located on the edge of RK Puram’s Sector-5 adjacent to the Outer Ring Road and the 1st breakthrough here took place from the opposite end (Munirka side) on December 29, 2015 by its sister machine THI-1 – see details & images here.
Recent satellite imagery of the mid-shaft:
With this breakthrough out of the way, now only 1 more TBM breakthrough is left on the entire line. This last one will take some time and might drag the tunneling phase up until November.

The DMRC’s MD, Mangu Singh, recently admitted to delays in both the Pink & Magenta lines’ construction which took everyone in Delhi and outside by surprise, but if you’ve been following the Delhi section of the site, then this revelation is nothing new. A new official deadline is yet to be announced by them, so stay tuned for that.

So when can we expect final commissioning of full route.
Full route: Q1-Q2 2018
The Botanical Garden – Kalkaji elevated section should open up in Q2-Q3 2017.
Isn’t Delhi metro keeping a target to open the section between Jasola Vihar to Kalkaji Mandir as soon as possible probably by the end of this year?
I think the same they will open the link between Kalindi kunj-kalakaji by end of the year.
Extensive trial runs are yet to begin. Keep in mind that this time around, they will have to test new components which’ll take more time – CBTC signalling and platform screen doors.
Is the work has started on redesigned pillars over nh 24 between vinod nagar and vinod nagar east metro stations.
Yes, a pillar has started to take shape on one of NH24’s lanes.
What is the update on that partly demolished building after ip extension metro station.
DMRC is negotiating with the owner right now.
When it is expected to be solved. Will it be solved in two months till October.
