The Calcutta (Sealdah)–Kusthia line of Eastern Bengal Railway was opened to run in the year of 1862. Eastern Bengal Railway worked on the eastern side of the Hooghly River. The British Government in India established the railway station in the then Roosvelt town named Chandmari Halt in 1883. In 1953 it was renamed into Kalyani. In 7 April 1979, the track was extended from Kalyani main to Kalyani Simanta station[3] and also established direct connectivity to Kolkata through Kalyani Simanta local EMU trains.[4] The distance between Sealdah and Kalyani main station is 48 km.[5][1] Services of Kalyani Local started on 1963 after completion of electrification of Sealdah–Kalyani section. Initially, 4 pairs ran, after that, 7 pairs started in 1970. EMUs of that age were push-pulled by WAM-2 due to shortage of rakes. From 1963 to 1970, all the EMUs were 4 car rakes, namely T-S-M-T ( trailer seating motor trailer ) combinations . From 1970, they were converted into 9 car rakes . The Motor car had the DC pantograph, not like today's driving cars which have AC pantographs. A single, industrial line was extended to present day Kalyani Simanta and electrified in the late 1977.
Electrification
The Sealdah–Ranaghat route was electrified in the period of 1963–64.[6] Subarban traffic first started as Naihati Local and Kalyani local for the first time .
