Mumbai's metro system expanded with the simultaneous opening of two new lines, but their receptions were starkly different. Metro Line 9, connecting Kashigaon to Dahisar, was a hit, attracting significant ridership on its first day as commuters from Mira Road and Bhayander celebrated the reduced travel times of 15–20 minutes. Many praised the line's integration with existing services, enhancing convenience. In contrast, Metro Line 2B, running from Mandale to Diamond Garden, struggled to gain traction, recording only 250 passengers by mid-afternoon. Commuters noted that the line lacks essential connectivity to the monorail and major commercial districts, limiting its usefulness. Experts believe that Line 2B's potential will only be realized once it extends to key areas like Kurla, Bandra, and Andheri. The Mumbai Metropolitan Region Development Authority (MMRDA) did not release official ridership figures for Day 1, breaking from their usual practice.
