In a significant milestone for Mumbai's metro network, the Chief Commissioner of Rail Safety (CCRS), New Delhi, has granted safety certification for the regular operation of Mumbai Metro Line 7 (Red Line) and Metro Line 2A (Yellow Line). This certification marks the successful compliance with all conditions set during the provisional authorization, enabling unrestricted operations at a full capacity speed of 80 kmph—an increase from the previous temporary speed limits of 50 to 60 kmph at certain locations.

Both lines, operated by the Mumbai Metropolitan Region Development Authority (MMRDA), play a crucial role in reducing congestion on Mumbai’s busiest routes. Metro Line 2A stretches 18.6 km from Dahisar to DN Nagar, with 17 stations, while Metro Line 7 spans 16.5 km from Andheri (East) to Dahisar (East), with 13 stations. Together, they cater to over 2.5 lakh daily passengers, with cumulative ridership exceeding 15 crore since the start of operations.
