Phase II Extension of Kolkata Metro's Blue Line

There are plans to replace the steel third rail on the Blue Line with an aluminum third rail. This change will reduce the time interval between trains from 5 minutes to just 90 seconds. The main objective of this upgrade is to save energy and reduce operating costs. Indian Railways has approved this proposal. After the construction of the third rail, work will begin on installing communication-based train control signals, which is expected to be completed within the next 2 years. The entire project is planned to be completed in 2-3 years.
