Chennai Metro Purple Line Extension

The Chennai Metro's Purple Line is being developed under Corridor 3 of Phase 2. It will be approximately 45.8 km long from Madhavaram Milk Colony to Siruseri SIPCOT and has 50 planned stations. In September 2023, CMRL submitted a feasibility report for extending the corridor from Siruseri to Kilambakkam Bus Terminus. This study recommended improved bus services instead of metro services along that section due to low projected ridership. Therefore, this additional extension should not be shown as an approved metro line under construction.
