TBM S496 Makes a Breakthrough at Delhi Metro’s Gurdwara Shaft

Last week, TBM S496 – the 3rd tunnel boring machine operated by the CEC-CICI JV made a breakthrough at the Delhi Metro’s Gurdwara Emergency Shaft in north Delhi’s Rameshwar Nagar for package CC-04 of the 160 km Phase 3 project. This TBM was commissioned from the Majlis Park Ramp in April 2016 and is the 2nd of 2 ‘rescue’ TBMs to be leased from the HCC-Samsung JV (CC-34 on Magenta Line) and deployed for constructing the pending 600m down-line tunnel of the 58.596 km Pink Line‘s Majlis Park – Azadpur section.

For further reading on the Gurdwara Shaft and why this shaft became necessary to be constructed for commercial operations to begin on the Pink Line, see the following posts:

The up-line tunnel of this section was constructed by TBMs S495 (rescue) and S781 (original) which made breakthroughs in November-December 2016. Here’s a post-cleanup image shot from S781’s tunnel looking into the Gurdwara Shaft and further into the tunnel built by S495. There are still no signs of track-work here, so it it’s unlikely that we’ll anytime soon even see the new Hyundai Rotem trains being pushed through the tunnels for testing the Azadpur – west Delhi section of the line.

With this breakthrough out of the way, now only TBM S780 – one of the original TBMs deployed from Azadpur needs to make a breakthrough and have its parts retrieved. As per one source, the contractor plans to leave the TBM’s shell behind & only retrieve its internal parts. Its back-up gantry was removed from its rear-end and out of the Azadpur Station’s TBM shaft in late 2015.

      All tunnels have been built and currently interior finishing works + sub-system (tracks, signalling, telecommunications etc) installation is going on. And no, trial runs on IGD-Kalkaji have not started.

    What about trial runs on pink line now ?????

      Give it another 3-4 more months? Looks like they’re waiting for the 4th TBM to come out before even sending a train down through the ‘freed up’ tunnel shown above. As per some Twitter followers, electrification on the Mukundpur and Shakurpur ramps has not been completed yet.

        Hii TMRG the OHE work is started at Sakarpur ramp and the texture paint working n FOB work also started at Rajouri Garden metro station of pink line so now when the trial run starts on pink line ????

        • TMRG says:

          Like I said, give it 3+ months. The start of testing on the north-west-south Delhi section of the line is primarily dependent on the construction & freeing up of the tunnels between Azadpur – Majlis Park.

    How much time last TBM takes to retrieved on pink line ?????

    Reply
    • TMRG says:

      S780 should be out within the next 1 month after they’re done dismantling S496 and retrieving its parts. That TBM is one of the original TBMs deployed for CC-04 and has been sitting at the same spot for about 2 years now.

    Hey TMRG, Do You have any information regarding the progress of Metro Extension in Ghaziabad ?

      Hi, I haven’t heard of any plans to extend the Red Line beyond the New Bus Adda Station. There are however plans to extend the Blue Line’s branches from both Vaishali and Noida Sec-62 to Mohan Nagar. Both are in the ‘proposal’ stage right now.

      • Shobhit says:

        Thanks for the information. It will be of great help if you can provide any updates regarding the completion status of Red Line extension.

        Will it be added in phase 4 plan? Are there any chances?

        Reply
        • TMRG says:

          It could be added at a later stage if the GDA shows interest, releases funds for its DPR and then releases funds for its construction.

      No, the demolitions have not yet taken place. Alternative accommodation is being built opposite to the area in concern. What I got to know is that perhaps the line will be kept ready till the mayur vihar pocket 1 station for the trials to start and therefore line reversal facilities have been added there. TMRG, can you confirm this development?

      • TMRG says:

        Hi, I don’t have an update on Trilokpuri. The good news is that demolition at Hasanpur has commenced! With this, the DMRC will be able to launch operations from IP extension to Maujpur in 2018 when the gaps at Hasanpur and Anand Vihar are filled.
