A key milestone was achieved on the Purple Line of Kolkata Metro when tunnel workers completed a breakthrough between Khidderpore and Victoria. The breakthrough signifies that the tunnel boring machines have successfully passed through the designated stretch, allowing a continuous tunnel to be formed.
The achievement is a critical step in advancing the Purple Line’s construction schedule. It paves the way for the installation of track infrastructure, signalling systems, and station facilities in the coming months.
City authorities have highlighted that the tunnel breakthrough brings the project closer to completion and reaffirms the commitment to expanding Kolkata’s metro network. The next phases will involve detailed engineering work and quality inspections before the line can be opened for public use.
