The Bengal Central Railway was formed in 1881 to construct and operate a line to Khulna. It was merged with Eastern Bengal Railway in 1903.
The 33.06 km (21 mi) long 1,676 mm (5 ft 6 in) wide broad gauge line from Barasat to Hasnabad was constructed between 1957 and 1962.
The Sealdah-Ranaghat sector and the Dum Dum-Barasat-Ashok Nagar-Bangaon sector were electrified in 1963–64. The Dum Dum-Dankuni sector was electrified in 1964-65
About Dum Dum :
Dum Dum is a populated municipality now corporation under Barrakpore Commissionaire April 2015 by Smt Mamata Banerjee Chief Minister West Bengal near north Kolkata. It comes under Barrackpore sub-division and North 24 Parganas district of the state of West Bengal. It is a part of the area covered by Kolkata Metropolitan Development Authority. It is one of the main entry points to the city of Kolkata, providing a number of transportation facilities into that city from the northwest, such as Netaji Subhas Chandra Bose International Airport, formerly Dum Dum Airport, which offers domestic and international flights. Dum Dum has developed into a modern commercial centre and also hosts the Ordnance Factory Dumdum (OFDC) and Gun & Shell Factory Cossipore(GSF) of the Ordnance Factories Board, which manufactures armaments and other equipment for the Indian Armed Forces, Navy & Air Force. Dum Dum region is about 10 km from the city centre, defined as the Esplanade, Kolkata. The nearby localities include Nager Bazar, Motijheel, Ghughu Danga, Private Road, Chatakal, Jawpur, Rajbari and Lal Bagan.
Dum Dum railway station is on the Sealdah–Ranaghat line. The railway station and the metro station are in the same complex. The Circular Railway also terminates at the same station. The other stations in Dum Dum are located at Dum Dum Cantonment and Patipukur (on the Circular Railway line) and Airport Gate No 1 (on the single Airport line). Travel to airport by rail is inconvenient, as there are only a few trains at odd hours.
The Kolkata Metro previously terminated at Dum Dum metro station on the boundary of Dum Dum, with Dum Dum Road leading to the city and areas beyond. Since 2013, the line has been extended northwards to include the newly constructed Noapara station, which serves as the terminal point (north). However, the majority of trains still terminate at Dum Dum station, as it is better connected to other regions than Noapara.
