India, August 2026 – The ₹2,184-crore Borivali–Virar fifth and sixth-line project is being implemented under the Mumbai Urban Transport Project-IIIA across a 26-kilometre section of the Western Railway suburban network. The project is targeted for completion in 2029 and is intended to address capacity constraints along one of Mumbai’s busiest rail corridors.
The additional tracks are designed to improve separation between suburban services and other train movements, creating greater flexibility for local operations. Construction is progressing across three major bridges, three minor bridges and a road overbridge, alongside substantial earthworks. Around 1.30 lakh cubic metres of earthwork has been completed across the Bridge 75–Naigaon and Panju Island stretches, with another package recording about 70,000 cubic metres.
Land acquisition and infrastructure relocation remain important components of delivery. About 11.929 hectares of salt-pan land at Umelman in Vasai has been handed over, while remaining acquisition is continuing. Forest and mangrove clearances have been secured, and railway structures at Dahisar, Mira Road, Bhayander, Naigaon, Nallasopara and Vasai Road are being relocated or have reached advanced stages of relocation.
The project is being delivered within an existing, densely used railway environment, requiring construction to proceed alongside active suburban operations and established urban settlements. New foot overbridges and platform works are also planned at Dahisar, Naigaon and Nallasopara, demonstrating that the capacity programme extends beyond track construction to supporting station infrastructure.
Once completed, the additional lines are expected to reduce conflicts between different categories of trains and provide greater capacity for suburban services. For Mumbai’s rail network, the project represents a key infrastructure intervention aimed at converting additional track capacity into more reliable operations and easing pressure on the Borivali–Virar corridor.

Capacity expansion is becoming increasingly important on Mumbai’s heavily used suburban rail corridors, where local and long-distance services compete for limited infrastructure. The Borivali–Virar fifth and sixth-line project has reached around 30% physical progress, advancing a major effort to increase capacity and improve operational reliability.
