Maidan is an underground metro station on the North-South corridor of the Blue Line of Kolkata Metro in Kolkata, West Bengal, India.[1] [2] [3] The station is located on Jawaharlal Nehru Road at Middleton Street. It is named after the Maidan, the largest urban park in Kolkata, which lies on the west side of Jawaharlal Nehru Road.
In 2024, Kolkata Metro began replacing the steel third rail on the Blue Line with a highly conductive aluminum rail. This upgrade, the first in 38 years, aims to cut energy loss by 84%, saving approximately ₹1 crore per kilometer annually. The initial shipment from Germany covers about 5 kilometers, with a total of 35 kilometers planned over two years. The aluminum rail will reduce voltage drops, leading to faster travel times, more frequent services, and lower operational costs, while also cutting carbon emissions by 50,000 tons over its lifetime.[4]
