NATM Tunneling Works Completed at Delhi Metro’s Kashmere Gate

On November 24, a crew from the ERA-Mosmetrostroy JV team for package CC-07 of Delhi Metro’s Phase 3 project successfully completed tunneling works on a pair of 220 meter long tunnels for the Violet Line from the Kashmere Gate Station to a shaft located adjacent to the Haryana Canal Guest House. These pair of tunnels, as part of the line’s 5.37 km extension from ITO to Kashmere Gate, were built using the New Austrian Tunneling Method (NATM) that was also recently used to build a small 176m section of the Magenta Line at Kalkaji Mandir.

These tunnels are located north of the station’s platform and will allow trains to be reversed . If the Violet Line gets extended northward in the future, then the TBMs to build its extension will commissioned from this shaft.

Tunneling works on the rest of the 5.37 km ITO-Kashmere Gate line were wrapped up using Tunnel Boring Machines in March 2016. The DMRC, on their website, has been targetting a December 2016 opening and recently blamed the fall-out from the government’s demonitization initiative for causing further delay, but it’s quite evident why the line’s commissioning has been delayed. As per my estimate, the line will only be able to open up for commercial operations in the 2nd half of 2017.

    This project just got a lot more interesting. I thought all work was complete and trial runs were being conducted throughout. I wonder what else DMRC is hiding?

    The DMRC website got updated yesterday and it is written there about the time for commissioning of this small stretch as December last week. DMRC seems to be fooling people or something is going wrong with their publicity team.

    Atleast DMRC can extend double line to ITO/Delhi Gate, so that waiting time for/from ITO can be reduced from 10-12 min to 4-5 minutes.

    DMRC should also consider increasing the speed of Red Line trains, so that time can be reduced to Rithala by atleast 5 minutes.
