The Mumbai Railway Vikas Corporation (MRVC) has achieved a monumental breakthrough with the completion of the 2,625-meter Wavarle tunnel, marking the longest tunnel in Mumbai’s suburban railway network.
Part of the Panvel-Karjat railway project under the Mumbai Urban Transport Project-3 (MUTP-3), the construction of this tunnel commenced on February 22 last year. MRVC’s Chief Public Relations Officer, Sunil Udasi, lauded the accomplishment, highlighting that the project also includes the construction of two other tunnels—Nadhamuni (219m) and Kirawali (320m)—totaling 3,164 meters. With 50% of the Rs 2,782-crore project completed, MRVC aims to inaugurate the line by December 2025.
Employing the innovative Austrian tunnelling method, the construction of the Wavarle tunnel encountered various challenges, including fractured rock masses and water seepage, compounded by minimal cover depths as low as 12 meters. Despite these hurdles, meticulous planning facilitated an average excavation output of 175 meters per month, showcasing the project’s resilience and efficiency. The Wavarle tunnel boasts state-of-the-art features, including a ballastless track, public refuge areas, advanced tunnel control systems, and internationally compliant lighting, firefighting, and ventilation systems. Standing at 7.32 meters tall and 13.28 meters wide, it sets a new standard for railway infrastructure in India.
Upon completion, the double-line corridor will significantly enhance connectivity, facilitating local train services between Mumbai and Karjat via Panvel. This development is poised to catalyze economic growth and urban development in regions spanning Navi Mumbai, Raigad district, and the proposed Navi Mumbai Airport Influence Notified Area. Amidst land acquisition challenges and regulatory approvals, MRVC has made substantial progress, initiating station building works at key locations along the route. As Mumbai’s suburban rail network evolves, the completion of the Wavarle tunnel marks a pivotal milestone in the city’s journey towards enhanced transportation infrastructure and connectivity.
