Four express trains, including Bolpur Santiniketan-Howrah Express and Rampurhat-Sealdah Maa Tara Express, will be rescheduled on Sunday owing to a block for track maintenance work in Howrah division of Eastern Railway. Civic and transport authorities are coordinating field operations to improve commuter safety, reduce transit bottlenecks, and streamline daily travel across key urban corridors. Commuters have been advised to check updated schedules and route advisories.
