Mumbai Metro Line 2B Trials Start between Mandale and Diamond Garden

25 Apr 2025 CW Team

This new phase of testing will focus on assessing key technical parameters such as braking performance, acceleration control, power consumption, signaling systems, and telecommunications reliability, all essential for ensuring the system's safety and smooth integration. Following the successful internal trials, the system will undergo a comprehensive evaluation by the Research Design and Standards Organisation (RDSO) under Indian Railways. The assessment will determine the project’s operational readiness. If the system passes, certification from the Independent Safety Assessor will follow, clearing the way for a public rollout.

While the full stretch of Metro Line 2B from DN Nagar to Mandale was originally scheduled for completion by December 2025, the timeline has now been extended to early 2026 for key sections like Diamond Garden to DN Nagar. This change is seen as a strategic decision by MMRDA, which prioritizes safety and infrastructure integrity over expedited timelines.

For urban mobility experts and sustainability advocates, Metro 2B represents more than just improved commuting. It highlights a commitment to low-emission public transport solutions in India’s most densely populated city. With Line 2A (Dahisar to DN Nagar) already operational and receiving positive public feedback, the integration of Metro 2B will offer a seamless connection between key residential and commercial areas such as Chembur, Kurla, Bandra East, and Andheri. These regions, which have long struggled with traffic congestion and limited last-mile connectivity, are now looking forward to reduced travel times and boosted economic activity. The corridor is also expected to foster micro-local real estate growth, especially near station zones, by improving access and alleviating congestion on traditional routes like the Eastern Express Highway and the Harbour Line.

Urban planners view the resumption of trials as a crucial milestone for the MMRDA, reflecting the agency’s renewed focus on creating equitable, climate-resilient transport infrastructure. With the Mandale depot now operational and infrastructure work accelerating, the city’s vision of an integrated metro network is gradually becoming a reality. For millions of daily commuters enduring long hours in traffic or crowded trains, the metro’s promise of accessibility, speed, and sustainability offers not just convenience but also a vision of what urban India must evolve into.

The Mumbai Metropolitan Region Development Authority (MMRDA) has begun trial runs on a crucial 5.3-kilometre section of the long-awaited Metro Line 2B, which connects Mandale to Diamond Garden. This operational trial, covering five key stations, including Mankhurd and Shivaji Chowk, is a significant milestone for commuters who have long relied on overcrowded roadways and suburban trains for cross-city travel. The 18.5-kilometre Metro 2B corridor, extending from DN Nagar in the west to Mandale in the east, has faced delays due to challenges related to land acquisition, funding, and the COVID-19 pandemic. However, with the completion of the Mandale depot—an expansive double-decked facility covering 31 acres and capable of housing up to 72 trains—the project now appears to be gaining momentum. This new phase of testing will focus on assessing key technical parameters such as braking performance, acceleration control, power consumption, signaling systems, and telecommunications reliability, all essential for ensuring the system's safety and smooth integration.
