Kolkata Circular Railway is a railway line that encircles the entire city of Kolkata. It starts from Dum Dum Junction in the north and passes through Chitpur, Burrabazar, B.B.D.Bagh, Prinsep Ghat, Hastings, Kidderpore, Remount Road, Majherhat, Ballygunge, Sir Gurudas Banerjee Halt and finally back to Dum Dum Junction. With the increasing population of Calcutta metropolis, and road transport being unable to cope with the demand due to bottlenecks in roads, it was felt necessary to introduce some other source of transport which will ease off the problem particularly at peak hours.
