Metro Line 4, extending 32.32 kilometres with 30 stations, connects Wadala to Kasarvadavali, while the 2.7-kilometre Line 4A links Kasarvadavali to Gaimukh. Together, these lines are poised to alleviate traffic congestion, reduce travel time by 50-75%, and provide seamless integration with existing and future metro corridors. Despite ongoing work on the designated depot, MMRDA has implemented an interim plan, including inspection pits beyond the terminal station at Gaimukh, to facilitate early operations and ensure the timely commencement of trial runs.
The trial phase encompasses dynamic testing, including load evaluations, signalling and traction checks, as well as emergency preparedness drills. These comprehensive assessments are crucial to ensure the safety and reliability of the metro system before full-scale operations begin. The successful completion of these trials will pave the way for the commencement of services, offering commuters an efficient and sustainable alternative to road transport. The integration of Metro Lines 4 and 4A into Mumbai’s broader transportation network underscores the city’s commitment to enhancing urban mobility and reducing carbon emissions.
By providing a reliable and eco-friendly mode of transport, these metro lines contribute to the creation of a zero-net-carbon, sustainable, and equitable urban environment. As the trials progress, MMRDA remains focused on addressing any challenges promptly to ensure the seamless integration of these metro lines into Mumbai’s public transport system. The successful implementation of Metro Lines 4 and 4A is expected to significantly improve connectivity, reduce traffic congestion, and promote sustainable urban development across the eastern corridor.
