The station from where the lines bypassing Sealdah emerge out only to meet the lines coming from Sealdah North section. Thus, the bypass line acts and serves as the connecting link between the North and South sections of Sealdah. The bypass line didn't have any platform earlier until it was decided by the railway authorities to add two seperate platforms to the existing double-discharge single platform of late. The area is dotted with leather factories. Park Circus also has a Tram Depot.
The super structure that stands tall just beyond the station premises is actually the longest flyover of Kolkata - the Park Circus-Parama Island Flyover which was rechristened as the 'MAA' Flyover, meaning mother. This main flyover spans 4.5 Km while its flanks and ramps stretch it to 9.1 Km.
