👉 Construction work is expected to begin by the end of January.
🔑 Key Highlights (Simple & Clear)

⏱️ Benefits: Reduced crowding, faster journeys, more frequent services
🛤️ Why This Project Is Important
Railways are one of India’s most vital transport services, carrying lakhs of passengers daily.
From Chennai, thousands of trains operate every day, with suburban services playing a crucial role.
On the Chennai Beach – Tambaram – Chengalpattu route, over 500 electric trains run daily, serving thousands of commuters.
After the Kilambakkam Bus Terminus became operational, Tambaram and Chengalpattu stations gained even more importance, as many passengers prefer suburban trains for connectivity.
🚦 Current Challenge
Although many electric suburban and express trains operate on this corridor, only three tracks are currently available. This limits the ability to add more services and causes congestion during peak hours.
🚀 What the 4th Line Will Do
Enable 100 additional electric trains
Improve connectivity between Chennai city and its suburbs
Reduce overcrowding and delays
Support future population growth and transport demand
📢 Great news for commuters! A new path is being built for a rail revolution in Chennai’s suburbs.
