Indian Railways has approved a project to double the 68 km long rail line between Arakkonam and Chengalpattu. This project will cost approximately ₹993 crore and aims to improve travel for local train passengers and freight movement in Chennai. The decision follows an evaluation by the Network Planning Group under the PM GatiShakti National Master Plan.
What are the main benefits of this project?
Railway Minister Ashwini Vaishnaw stated that this project will reduce congestion on the busy suburban rail network of Chennai. It will improve the punctuality of trains and overall operational efficiency. The doubling of the line will significantly increase the capacity of daily trains from 13 to approximately 40. This will make commuting easier for thousands of daily passengers.
How will this impact goods and industrial transport?
The project will strengthen the movement of essential goods like cement, automobiles, food grains, and iron and steel. Since the line serves major industrial hubs, it will provide a boost to the local economy. The key areas benefiting from this include:
- Mahindra World City
- Sriperumbudur
- Oragadam
- Irungattukottai
Additionally, the line is strategically important due to its proximity to the proposed Parandur Airport near Kanchipuram.
