A senior official of Kolkata Metro said that the entire E-W metro corridor between Howrah Maidan to Salt Lake Sector V is expected to be operational soon. This will connect Sealdah and Howrah stations, the two busiest railway stations in India.
“The interior of the tunnels has been specially illuminated with blue lights in a bid to give passengers an impression of an underwater world. At least 40 figures of illuminated fishes have been set up on the interior walls. Plans are also afoot to give some special sound effects in this under-water section,” said an official.
Kolkata Metro is the first metro system in India which became operational on October 24, 1984.
