After a long 15 years gap, new tram route construction had started again in 1925. The Nonapukur line was extended to Park Circus via Park Street (now Mother Teresa Sarani) for serving residents and circus goers of that area. Park Circus tram depot was also constructed at that time. In the next year, the direct access of the Behala line via Orphanganjbazar was replaced by present alignment via Wattganj junction for smooth tram service. A new terminus near Racecourse was constructed in next year for race special trams towards Belgachhia, Bagbazar, Galiff Street, Rajabazar, High Court, Nimtala, Park Circus, Tollygunge, Behala & Khidirpur. In the next year, a new branch was constructed from Kalighat to Ballygunge, another then south suburb of Kolkata via Ballygunge Avenue (now Rasbihari Avenue).
