Kolkata Metro has achieved a significant milestone as it became the first metro rail in India to complete an under-river journey. The metro rakes passed through an underwater tunnel beneath the Hooghly river, with the general manager, P Uday Kumar Reddy, traveling from Mahakaran to Howrah Maidan station in rake No. MR-612 at 11:55 am. Senior officers, including the Additional General Manager and MD of Kolkata Metro Rail Corporation Limited (KMRCL), H N Jaiswal, also accompanied him during the historic journey. After reaching the Howrah station, Reddy performed a puja, and rake No MR- 613 was also taken to the Howrah Maidan station. Flowers were sprinkled and coconuts were broken to celebrate this achievement.

The four stations on this stretch include Esplanade, Mahakaran, Howrah, and Howrah Maidan.
- Once operational, Howrah will become the deepest metro station in the country, situated 33 meters below the surface. Commercial services are expected to begin later this year. Currently, the East-West Metro Corridor (Green Line) is operational between Salt Lake Sector V and Sealdah stations over a stretch of 9.3 km. The Howrah Maidan to Esplanade stretch will provide an interchange point at Esplanade with the North-South Corridor (Blue Line).
