Chennai expands Metro Rail for better urban commuting

Chennai is expanding its Metro Rail system to improve urban commuting. New corridors will connect key areas, including a 6km line from Lighthouse to Madras High Court and a 21km route from Tambaram to Velachery. Additional corridors are planned to link the airport to Kilambakkam and Poonamallee to Sunguvarchathiram. A Regional Rapid Transit System (RRTS) will connect Chennai to Villupuram and Vellore, with stops every 10-15 km. Concerns have been raised about the affordability of the metro and RRTS for daily commuters. Some experts suggest that improving bus services could be a more cost-effective solution.
