TBM Makes 4th Breakthrough at Delhi Metro’s Panchsheel Park Station
And yet another breakthrough! This is the 2nd one for the month after the breakthrough at Mayapuri Shaft a couple days ago.
On the morning of March 7, the THI 15 Tunnel Boring Machine (TBM) deployed by the FEMC-Pratibha JV (CC-23) for Delhi Metro’s Phase 3 project made a breakthrough at the Panchsheel Park station! This TBM excavated and built a roughly 635m long tunnel for the new 38.235 km Magenta line’s down-line after being commissioned from the Chirag Delhi station in August 2015.

This is the 4th breakthrough to take place at the Panchsheel Park station. The first 2 took place from the Hauz Khas side. For details and images of the previous breakthroughs, see the following posts:

• October 21 2015 – Delhi Metro TBM Makes a 2nd Breakthrough at Panchsheel Park Station on Magenta Line
• December 10 2015 – Delhi Metro TBM Makes a Breakthrough at Magenta Line’s Panchsheel Park Station
With this breakthrough, all twin tunnels on the 6.1 km stretch between Munirka – RK Puram – IIT – Hauz Khas – Panchsheel Park – Chirag Delhi stations are now complete! Now only 7 more breakthroughs are left to be made on the Magenta line:
| Contract | Contractor | Origin | Destination | Tunnel |
| CC-23 | Pratibha – FEMC | Greater Kailash | Nehru Enclave | Down-line |
| CC-23 | Pratibha – FEMC | Chirag Delhi | Greater Kailash | Up-line & Down-line |
| CC-27 | L&T – SUCG | Shankar Vihar | Aravali Mid-Shaft | Down-line |
| CC-27 | L&T – SUCG | Vasant Vihar | Aravali Mid-Shaft | Down-line |
| CC-27 | L&T – SUCG | Vasant Vihar | RK Puram Mid-Shaft | Up-line |
| CC-27 | L&T – SUCG | Vasant Vihar | Munirka | Down-line |
For a comprehensive report with progress made on all lines’ tunnels, please see my March 2016 Tunneling Update.
The TBM operating from Vasant Vihar to the Aravali mid-shaft for the down-line tunnel reached the mid-shaft’s diaphragm wall last night, so expect good news in the next 1-2 days. 🙂

Also post the pics of finished tunnels
All tunnels look similar to this after being built, so there isn’t anything unique about them to share. Once all track-work and signalling/electrical systems are installed, I’ll share some images.
If possible, can you please post about the progress of the Magenta line’s elevated corridor?
Hi, I post random images of the completed viaduct through my Twitter account: @TheMetroRailGuy. I’ll share updates here when there’s something significant.
