Kolkata East West Metro will ferry 1 million people a day by 2035: Railway official

The 16.6-km Kolkata East West Metro will ferry an estimated one million passengers per day by 2035, a senior Railway official said.

The project, to be completed by 2021, will also have the county's first underwater tunnel.

The 520-metre twin tunnel, one east-bound and the other west-bound, is built 30 metres below the riverbed. Commuters between Howrah and Mahakaran metro stations will be under the river for only about a minute when the train passes through the tunnel at a speed of 80 km per hour.

"According to our estimation, by 2035, one million passengers will be using this metro line every day," the official said.
