Girish Park is an underground metro station on the North-South corridor of the Blue Line of Kolkata Metro which is close to Girish Park in Jorasanko, Kolkata, West Bengal, India.

The aluminum rail’s superior conductivity is expected to reduce voltage drops, leading to faster train acceleration and shorter travel times.

The project began with preparatory work at night to avoid disrupting daily services and is part of a larger initiative to modernize the entire 35 km stretch of the Blue Line over the next two years.

The upgrade includes installing additional substations to support the enhanced train frequency, bringing Kolkata Metro in line with global standards.
