Chennai Rail Network to Expand with New Fourth Line Between Tambaram and Chengalpattu

CHENNAI, INDIA – October 23, 2025 – Commuters in Chennai can expect improved railway services following the approval of a new fourth railway line between Tambaram and Chengalpattu. Union Railway Minister Ashwini Vaishnaw sanctioned the project, estimated to cost ₹713.56 crore, with an escalation cost projected at ₹757.18 crore.

The move comes as the Tambaram railway station is being developed as the third major railway terminal in Chennai, after Dr. MGR Chennai Central and Egmore. The existing Tambaram-Chengalpattu section, a crucial mainline connecting Chennai to Villupuram, Tiruchi, and Kanniyakumari, is currently operating at a high 87% track utilization with only three tracks handling both suburban and mail/express trains.

“This project is vital for easing congestion and providing dedicated suburban train services,” stated a press release from the Southern Railway. “We anticipate a significant modal shift from road to rail as a result, greatly benefiting thousands of passengers daily.”

The Southern Railway will execute the project, which was greenlit after a detailed project report was submitted to the Railway Board and subsequently approved by the Chairman and other members. The addition of the fourth line is expected to improve punctuality and reduce delays, enhancing the overall commuting experience for residents of Chennai and those travelling further south. Construction is expected to begin in the near future, with a timeline for completion yet to be announced.
