Howrah metro station

Built underneath the Howrah railway station's new and old complex, the metro station allows interchanging with other zones of Indian Railways as part of the Howrah station transport hub. It is the deepest metro station in India. To the east, the station connects to Mahakaran station in Kolkata through India's biggest under-river metro tunnel beneath the Hooghly river; whilst to the west the adjacent station is Howrah Maidan.

History

The master plan had already identified the East-West corridor back in 1971. It was planned to connect Howrah Railway Station with the Salt Lake region. As per the feasibility investigation for the corridor conducted by Pacific Consultant International Group in January 2004; their plan report proposed the route and tubular structures to be beneath the Hooghly River.
The Kolkata Metro Rail Corporation Limited was formed, to execute the operations of this line.
After extensive work, the Esplanade–Howrah Maidan section of Green Line was inaugurated on 6 March 2024. This station solely serves as a tourist attraction due to the underwater tunnel segment under Hooghly River, indicative of dense blue LED lights encompassing the segment.
