January 23, 2026The proposed Avadi–Sriperumbudur–Guduvancheri new railway line project in Tamil Nadu aims to connect Chennai's western and southern suburbs, significantly improving regional connectivity. A detailed project report (DPR) for this line has been prepared, with the project gaining traction as of late 2025 to enhance transport options.
Key details of the proposed Avadi–Sriperumbudur–Guduvancheri new railway line project include:
Route: Connects Avadi with Guduvancheri, passing through industrial hubs like Sriperumbudur.

Status: As of September 2025, the DPR was prepared, indicating progress in planning.
Impact: Expected to boost economic growth in the corridor and facilitate easier commutes for residents and workers in the suburban areas.
