This is my fifth post on a TBM breakthrough in Delhi in the last 7 days and I just can’t contain my joy! Posts on the previous breakthroughs can be read at the Delhi section of my website.
Unlike the previous breakthroughs on the Magenta line posted this week, this time the action has shifted to the 58.59 km Pink line that forms a ring around the city. The TBM deployed by the Delhi Metro’s contractor for the section between the RK Puram shaft and the Lajpat Nagar station, a joint venture of Pratibha & FEMC, made a breakthrough on September 14 at the Sarojini Nagar station after tunneling a distance of 1,105 meters from the Bhikaji Cama Place station.
This is the first breakthrough at Sarojini Nagar and the second one is expected within the next 2 months. Like earlier, the news media was not invited to cover the event, so there’s no mention of it in the papers or elsewhere.

While you’re here and reading this, you may want to check out a video of last month’s Lal Qila station breakthrough on the Violet line that Terratec, the TBM manufacturing company, just uploaded 2 days ago. I’ve posted it here: Delhi Metro completes Red Fort – Kashmere Gate tunnel.
