Chennai Metro Rail has issued bids to purchase 28 six-coach trains for the 54-kilometer Phase I and Phase I extension networks to meet the needs of growing passenger traffic.

The central government rejected Tamil Nadu's proposals for metro rail projects in Madurai and Coimbatore. The Ministry of Housing and Urban Affairs (MoHUA) cited population norms under the Metro Rail Policy 2017. Government sources said the policy allows metro systems only in cities with a population of over 2 million. According to the 2011 census, the Coimbatore Municipal Corporation had a population of 15.84 lakh, while the local planning authority area had a population of 23.5 lakh. In Madurai, the municipal corporation had a population of 10.20 lakh and the urban area had a population of 14.7 lakh.

While towering towers will be built at Chennai Central, Mandaveli, Thousand Lights, and Thirumangalam metro stations, CMRL will also construct additional floors for use as office space or for setting up retail shops at several stations, including Perungudi, Sholinganallur, Karapakkam, Thoraipakkam, Madhavaram High Road, Sembium, Ayanavaram, Otteri, Perambur Barrack Road, Purasawalkam, Chetpet, Sterling Road, Nungambakkam, Royapettah, Adyar Depot, and Thirumayilai.

Residents of Tiruvottiyur and Ernavoor staged a sit-in on Sunday, demanding extension of the Airport-Wimco Nagar Metro line to Ennore and Madhavaram, increasing the frequency of EMU services on the Chennai Central-Gummidipoondi suburban section and completion of the long-delayed Wimco Nagar Metro project. Addressing the protest organised by the CPM Tiruvottiyur North unit, CITU State vice-president A Soundararajan said many of the demands raised by the residents were nearly three decades old.
