Every working morning, roughly 93 lakh people squeeze into Mumbai's suburban trains, a number so staggering that the network is fast approaching one crore daily riders. On the city's busiest recorded day, January 5, 2026, Central Railway alone ferried 72.18 lakh commuters, and Western Railway moved 52.07 lakh. If you have ever taken a suburban train on a weekday in Mumbai, you know that it is the lifeline of India’s financial hub, and that it needs a plan to tackle this surge. The railways now have a detailed answer.
In a written reply to a Rajya Sabha question on Friday, Union Minister for Railways Ashwini Vaishnaw laid out the full scope of India's investment in Mumbai's suburban network, across three phases of the Mumbai Urban Transport Project (MUTP).
Big numbers for Mumbai suburban rail
Three successive phases of MUTP have together committed ₹52,724 crore to expand Mumbai's rail infrastructure. MUTP-II (₹8,087 crore), MUTP-III (₹10,947 crore) and the ongoing MUTP-IIIA (₹33,690 crore) together cover new rail corridors, additional platforms, pit lines and stabling yards across the city.
The push in capacity is headlined by the procurement of 238 new rakes, each with 12 cars fitted with doors, unlike older open-door rakes, sanctioned under MUTP-III and IIIA at a cost of ₹19,293 crore.
The procurement process has been initiated, informed the minister.
These will add thousands of seats daily to a network that, according to Central Railway's own data, already runs 1,820 suburban services per day, including 94 air-conditioned local services.
New lines and corridors
The infrastructure buildout includes 12 specific line additions and extensions. Among the most significant: a 26 km Borivali-Virar 5th and 6th Line (₹2,184 crore), a 64 km Virar-Dahanu Road 3rd and 4th Line (₹3,587 crore), a 7 km Goregaon-Borivali Harbour Line extension (₹826 crore) and a brand-new 29.6 km Panvel-Karjat suburban corridor (₹2,782 crore). A new elevated 3.3 km Airoli-Kalwa link (₹476 crore) will connect the Harbour Line to the trans-harbour zone, long demanded by commuters from Navi Mumbai.
Infrastructure works at stations are also underway, including additional platforms at Jogeshwari, Dadar and Kalyan, and new stabling lines at Virar, Dahanu Road and Mira Road to house the incoming fleet.
Safety on track, but gaps remain
The railway minister informed the Parliament that Consequential Train Accidents (CTA) have fallen 90 per cent from 135 in 2014-15 to just 14 so far in 2025-26. Moreover, the Accident Index improved 73 per cent from 0.11 in 2014-15 to 0.03 in 2024-25.
The anti-collision Kavach Version 4.0 has been commissioned on 1,452 route kilometres on the high-density Delhi-Mumbai and Delhi-Howrah corridors, with 4,154 locos equipped and 8,570 km of optical fibre cable laid.
In FY 2025-26 up to January, Central Railway's suburban network alone carried 120.19 crore passengers, up from 118.79 crore in the same period the previous year. With Mumbai's suburban population continuing to grow, and Metro lines carrying only around 9 lakh daily (nowhere near enough to absorb the overflow), the MUTP pipeline is the best hope for the city's commuting millions.
