Tunneling work on the last section of the Delhi Metro’s 38.235 km Magenta line has begun! On Sunday, the Pratibha-FEMC JV team for contract CC-23 of the Phase 3 project started tunneling work for the up-line tunnel from the Chirag Delhi station towards the Greater Kailash (GK) station. At the time of publishing this, 2 temporary rings have been placed.
Parts of this TBM were lowered into the launch shaft in November & December 2015. Here are a couple of images from a post from last month:
The distance between the Chirag Delhi and Greater Kailash stations is only 545m – one of the shortest on the line, so a breakthrough at Greater Kailash can be expected to take place in April this year. But wait..I have more news! A week prior to this TBM commencing work, the Pratibha-FEMC team started to lower parts for another TBM at the same shaft to bore the parallel down-line tunnel. That TBM will be the last on the entire line to start & complete work.
Over the next few weeks, the team will continue to lower more parts and assemble them to make the down-line TBM launch ready for its initial drive in mid-February.
