The proposed Airport - Kilambakkam metro extension of Blue Line will introduce Pallavaram Metro Station to serve Pallavaram and Pammal.

The Airport - Kilambakkam Metro Line was originally planned with a route via Pallavaram, Pammal, Thiruneermalai Service Road, and then Tambaram and straight along the GST road up to Vandalur Kilambakkam.

As part of the plan for the Chennai Mono Rail, there was a plan for a route between Vandalur and Puzhal via Pallavaram, Pammal, Kundrathur, Mangadu, Kumanan Chavadi, and Poonamallee High Road to reach Puzhal. Recently, CMRL announced feasibility for a Chennai Light Rail project between Tambaram and Velachery. After completion of the CMRL Phase I Extension from Airport to Kilambakkam and CMRL Phase II extension from Light House to Poonamallee, there will be a Chennai Light Rail connection between Pallavaram and Poonamallee via Pammal, Anakaputhur, and Kundrathur.
