The Story of My Mumbai Metro
Delayed Green Line 4 gets certification. Green Line 4 moves ahead! The Research Designs and Standards Organisation (RDSO) certificate, required for the first phase of the Green Line Mumbai Metro 4 project, was received on June 2, 2026. After a wait of approximately 209 days, this crucial certification marks a significant milestone in the direction of commencing metro operations.
Following the receipt of the RDSO certificate, MMRDA will now proceed to submit an application for inspection and approval by the Commissioner of Metro Rail Safety (CMRS), the next required step before metro services can be launched.
