Bolaka --- It is the first ever single car tram which moves both way, introduced into the service by CTC (Calcutta Tramways Corporation Ltd)) especially for the festive seasons like Durga Puja, Bengali New Year, Christmas. Fare minmum is Rs 10/- per head. But it never really runs on conventional routes like other trams. The name 'Bolaka' was derived from a book written by the great nobel laureate Kaviguru Rabindranath Tagore. Framed by Roy while it was resting at Esplanade junction on a afternoon of 28th Dec 2015.
