The Kolkata Metro Railway will soon connect the city's airport to the city centre through operational and under-construction metro lines cutting the journey from the Esplanade to the airport to 30 minutes, providing a huge infrastructural boost to Kolkata's metro network. The metro station at the airport will have five platforms and also an underground yard and will be connected to the terminal through subways. It will be the largest underground metro facility in India. NDTV brings you this sneak peek into the underground metro station.
