Here is the translation:
The key reasons for the approval of the fourth railway line between Tambaram and Chengalpattu are as follows:
🚆 Ease Congestion
The Tambaram - Chengalpattu section is a crucial part of the main railway line (Chennai Beach - Villupuram - Kanyakumari). The current three lines experience severe traffic congestion.
Track Utilization: The utilization of the existing three-line stretch is about 87%. It is projected to increase to 136% in the future if this project is not implemented.
Delays: Since Suburban, Express, Mail, and Freight trains all use the same lines, there are frequent delays. This affects the punctuality and the overall speed of the trains and the Time Table.
🚄 Separate Suburban & Express Trains
The construction of the fourth line will significantly improve operational efficiency.
Dedicated Line: The new line will be used exclusively for suburban electric trains. This means suburban trains will no longer have to wait for long-distance Express trains to pass.
Speed Increase: According to some reports, this fourth line is designed to accommodate trains running at a speed of up to 160 kmph. This will reduce travel time.
🏙️ Catering to Growth
The project takes into account the rapid development occurring in Chennai and its surrounding areas.
Passenger Volume: Due to residential and industrial development in and around Tambaram, Guduvancheri, Chengalpattu, and Sriperumbudur, daily passenger traffic is very high. This new line will be a great boon for daily commuters, including office-goers.
Kilambakkam Connectivity: With the new Kilambakkam bus terminus becoming operational, this fourth line will help in the smooth operation of suburban train services passing through Kilambakkam.
Freight Traffic: The project will aid the increasing freight movement to industrial clusters and SIPCOTs in areas like Oragadam and Padappai. It is expected to generate an additional 1.344 million tonnes of annual freight traffic.
Terminal Development: As Tambaram is being developed as a major Coaching Terminal, this new line will help meet future traffic requirements.
In summary, the project has been approved to reduce traffic congestion, enhance train operational efficiency, strengthen connectivity to the Southern districts, and fulfill the growing passenger and freight traffic demands of the region.
