Mumbai has moved to the second position in India for operational metro network length after recent additions pushed its total beyond 100 km, overtaking Bengaluru. The advance followed the commissioning of new stretches on Line nine and Line two B, which have strengthened links across Thane and the eastern suburbs. The expansion reflects accelerated execution across multiple corridors as authorities seek to improve urban connectivity. The Dahisar Kashigaon stretch on Line nine extended metro access towards the Mira-Bhayandar region while the initial section of Line two B between Mandale and Diamond Garden reinforced connectivity in the eastern suburbs. Together these additions contributed close to 10 km to the network, enabling Mumbai to cross the 100 km milestone. The growth is intended to ease pressure on suburban rail and road traffic by offering additional rapid transit capacity. Bengaluru's Namma Metro has moved to third place, with an operational network of around 96 km served by 83 stations. Over the past year the city added nearly 19 km, largely through progress on the Yellow Line, but delays in execution and rolling stock availability have slowed the pace of openings. The Yellow Line in particular required nearly three years longer than expected to become operational, affecting service frequency and train availability during peak hours. The pressure on Bengaluru's transport system has increased as vehicle registrations crossed 12.5 million (12.5 mn), with thousands of new vehicles being added daily and making timely metro expansion more critical. Bengaluru Metro Rail Corporation Limited is working on several corridors, with a seven km stretch of the Pink Line expected by mid-2026 and a section of the Blue Line between Silk Board and KR Pura targeted by the end of 2026, while airport connectivity has been pushed to 2027. Once these phases are completed the network is expected to expand to around 175 km. Delhi remains the largest metro network in the country and continues to lead in operational length and coverage.
