Kolkata on track for swifter travel with new Metro Railway East-West Corridor
Construction is currently underway on an immense infrastructure project in India. Lee Harris Pomeroy Architects composed the plans for the Kolkata Metro Railway East-West Corridor to formulate a complex design stretching a total route length of 14.67km – 8km of which are underground.
Costing €760m in total, the Metro Corridor is comprised of six underground stations, starting at Howrah Maidan, Howrah Station, Mahakaran, Central Station, Sealdah Station and ending with Phool Bagan, the last station before the alignment is elevated. Their work also included the design of entry pavilions, support structures, and development of adjacent properties. The design stuck rigidly to the brief, ‘conforming to the functioning of the operation of the trains’, featuring lightweight, airy and transparent pavilions suited to the Kolkata climate, maximising light and air to the underground entryways. All platforms will be air conditioned to ensure passenger comfort.
Depths vary throughout the 80,000 sq m of underground station construction, ranging from two floors below ground to five floors at the deepest point (45m), whilst station plans differ in size from 20m x 190m to 32m x 200m. The underground metro system will connect two of the largest long distance and commuter train stations in India (Howrah and Sealdah) each with a passenger load of approx. 1m per day. The Metro Corridor will also be the first train tunnel to be built under a river in India.
The project was worked on by an international consortium led by AECOM-Maunsell (UK), and including EGIS (France), YEC (Japan), CES (India), and Lee Harris Pomeroy Architects with SGI.
