Indian Railways has approved the Arakkonam-Chengalpattu Doubling Project (68 km) of Southern Railway at a cost of ₹993 crore, reinforcing its commitment towards safer, faster and more efficient rail transportation across the country.

The section forms part of the important Chennai suburban circular rail network connecting Chennai Beach, Tambaram, Chengalpattu and Arakkonam.

The Union Minister for Railways, Shri Ashwini Vaishnaw stated that the Arakkonam-Chengalpattu Doubling Project will play a significant role in easing congestion on the busy Chennai suburban rail network while improving punctuality and operational efficiency.

He said the project will strengthen both passenger and freight movement across the corridor, benefiting transportation of key commodities including cement, automobiles, food grains, iron and steel.

At present, the existing single line section is operating at a high level of capacity utilisation, and traffic is expected to increase further in the coming years, necessitating additional infrastructure augmentation.

The doubling work will help reduce detention time of trains, improve punctuality and increase the frequency of suburban services.

The route serves several major economic and industrial hubs including Mahindra World City, Sriperumbudur, Oragadam and Irungattukottai, along with important automobile, cement and manufacturing industries.

The proposed Parandur Airport project near Kancheepuram is also located close to the alignment, further increasing the strategic importance of the route.
