The Kolkata Metro network is undergoing significant expansion through various corridor projects. In August 2026, the Kolkata Municipal Corporation (KMC) issued a No Objection Certificate (NOC) for the Baranagar-Barrackpore Metro Corridor, known as the Pink Line. This clearance resolved a major obstacle involving a 48-inch drinking water pipeline located beneath B T Road, allowing Rail Vikas Nigam Ltd to proceed with construction plans for a 12.40 km stretch.

By September 2026, progress was reported on the Orange Line, specifically the 32-kilometer Kavi Subhash-Jai Hind Vimanbandar corridor. Metro Railway completed a push trolley inspection on the Beleghata-IT Center section, confirming the completion of viaduct and ballastless track work. The project is transitioning into electrical and signaling installation phases. Authorities intend to expand the existing 73-kilometer network to at least 130 kilometers.
