Kolkata Metro Purple Line gets tunnel breakthrough between Khidderpore and Victoria
On Tuesday, the Kolkata Metro's Purple Line made significant progress with the successful breakthrough of Tunnel Boring Machine Divya between Khidderpore and Victoria stations. This marks the completion of the second underground tunnel on the Joka-Esplanade Metro Corridor, following the earlier breakthrough by TBM Durga on July 10.
The 1.72-km tunnel drive was completed by Divya, which operates in Kolkata's soft soil and high groundwater conditions. The 6.60-metre-diameter TBM, 95 metres long, and weighing nearly 600 tonnes, is designed to withstand the challenging ground conditions. The successful breakthrough underscores the engineering excellence, meticulous planning, and teamwork involved in the project.
General Manager of Metro Railway, Kolkata, Prem Sagar Gupta emphasized that the team maintained strict quality and safety standards, ensuring that surface traffic and daily activities in the densely populated area remained unaffected. Upon completion, the Joka-Esplanade Metro Corridor will enhance Kolkata's Metro network, providing faster, safer, and more reliable connectivity for commuters.
