The metro interchange
Dum Dum metro station on the Blue Line, India's first metro line, connects to the railway station, giving commuters a direct route through central Kolkata. Many passengers use Dum Dum to transfer between suburban trains and the metro instead of continuing to Sealdah.
Close to the airport
Dum Dum Junction is only about 4 miles (around 6.5 km) from Netaji Subhas Chandra Bose International Airport. The nearby Dum Dum Cantonment station, opened in 1883, is even closer, about 3.9 km from the airport, and the two are often confused. For flights, check which of the two suits your onward connection.
Upgrades
Dum Dum has 5 platforms on 7 tracks, about 10 metres above sea level. In 2024 the Ministry of Railways allocated about ₹7.98 crore for its redevelopment under the Amrit Bharat Station Scheme.
