    Hey TMRG, did you go through the above link? Did you see anything surprising? Phase 1D of Jaipur Metro which you haven’t updated on your Jaipur Metro page in your website. Please update your website accordingly.

    Hi TMRG
    Can the lnt tbm’s of bangalore metro cab be used by ITD cem for tunneling nagavara to venkateshpura station as this could save the time.

    • Kartik says:

      It depends on ITD. If they want to buy that TBM from L&T then maybe they can. But they already have tunneling plans so it is unlikely they will deploy any new tbm.

    Small correction it is from Nagavara to KG Halli.
