A Tunnel Boring Machine (TBM) breakthrough at the Delhi Gate from Jama Masjid is expected to take place very soon! Larsen & Toubro, the contractor for the section between the Jama Masjid TBM shaft – Delhi Gate – ITO – Mandi House TBM shaft, has brought in a crane with a lifting capacity of 500 tonnes to lift the TBM out of the Delhi Gate Station right after the breakthrough is made.

As a reminder, L&T has deployed 3 TBMs along the ITO-Jama Masjid section:
- Mitsubishi 1 TBM
- Mitsubishi 2 TBM
- STEC 3 TBM
The Violet line is being extended by 9.37 km from Central Secretariat to Kashmere Gate. Here’s a map I’ve made that shows the line between Mandi House and Kashmere Gate:
The entire section has been divided into 3 sections handled by different contractors:
• Contract CC01 – Central Secretariat – Janpath – Mandi House – by Pratibha – CRFG JV
• Contract CC05 – Mandi House – ITO – Delhi Gate – Jama Masjid – by L&T-SUCG JV
• Contract CC07 – Jama Masid – Lal Qila – Kashmere Gate – by Era Infra-Metrostroy O.S JV
Out of these, the metro is currently operational between Central Secretariat – Janpath – Mandi House & ITO. The rest of the section from ITO to Kashmere Gate is expected to be operational only towards the end of 2016.
