For train passengers traveling to the southern districts, Tambaram is a very important terminal. The railway department is periodically making updates to ensure that trains from Tambaram to Trichy, Madurai, Tirunelveli, and Kanyakumari travel faster. In this regard, the work on laying the 4th railway line between Tambaram and Chengalpattu, at a cost of Rs. 713 crore, will begin next month.
