Welcome to the Kolkata Metro
The Kolkata Metro is the oldest metro system in India — the first line opened in 1984. Today it has grown into a five-line network of 55 stations covering around 73 km, operated by Metro Railway, Kolkata (a zone of Indian Railways). It carries the city beneath the Hooghly river, along the colonial core, out to the IT hubs and southern suburbs and direct to the airport.
