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:

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:
|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. 🙂
