Before 1978, there was a tram terminus at Sealdah station. Trams departed from here towards Rajabazar, Howrah Station, Calcutta High Court, Dalhousie Square, Park Circus and Dharmatala. The first horse tram service of Kolkata was also started from Sealdah to Armenian Ghat, following the current route 14 & 16 between Lebutala & Dalhousie Square. The Sealdah–Lebutala & Dalhousie Square–Armenian Ghat (later extended to High Court) stretch is now closed. That terminus was demolished in 1978 also with the Sealdah–Lebutala tram track stretched through Boubazar Street for construction of the Sealdah flyover. Now tram services between Rajabazar–Esplanade, Park Circus–Burrabazar and other services pass through Sealdah. Currently, a car parking exists in place of the old tram terminus.
