For tunnelling the first stretch from Khidderpore to Victoria station, TBM will start working from inside the premises of St. Thomas School at Khidderpore. For this, a launching shaft is required whose construction work at St. Thomas School is going o­n at present. Once this work is completed, TBM will start functioning to burrow the underground tunnels.
