Mumbai's suburban railway network, which spans approximately 450 kilometers and serves over eight million daily commuters, remains a vital but increasingly hazardous mode of transport. While generally regarded as safe, certain locations along the network present significant risks, particularly due to overcrowding, track-side encroachments, and challenging track geometry.

One of the most perilous spots is the 1.3-kilometer Parsik tunnel beneath Parsik Hill, operational for nearly a century. The tunnel’s approaches are flanked by densely populated slum settlements, where residents frequently cross the railway tracks despite the dangers. Poor lighting and the proximity of informal settlements force trains to reduce speed when entering and exiting the tunnel, yet accidents involving pedestrians remain frequent.

Adjacent to the tunnel lies a sharply curved section of track between Diva and Mumbra stations that has become notorious for accidents involving passengers clinging to the trains’ exteriors. Trains navigating the curve tilt significantly, causing some commuters standing on footboards—often a measure taken during peak overcrowding—to lose their balance and fall. A recently circulated video shows a woman gripping precariously to the outside of a women’s compartment while the train negotiates the curve, her sari nearly brushing the nearby support pillars. Such scenes are common, with hundreds enduring this risky commute daily, particularly during rush hours when carriages are packed beyond capacity.

Commuter activists highlight that women traveling from distant suburbs including Kalyan, Dombivli, and Diva regularly find themselves compelled to stand on footboards due to insufficient space inside compartments. Lata Arghade, a prominent activist, commented that for many women on this route, traveling during peak times often means choosing between job security and personal safety. Another activist emphasized how passengers from Thane and beyond face life-threatening conditions where mere inches of footboard space can determine their survival.

Railway records indicate that about 180 passengers have fallen from trains on the Thane-Diva stretch so far this year, with approximately one-third of these incidents proving fatal. A tragic example occurred in June 2025, when two trains passed the Mumbra curve simultaneously at high speeds in opposite directions. Passengers clinging to the exteriors of both trains collided, resulting in six deaths and multiple injuries.

More broadly, official statistics from 2025 reveal daily average fatalities of around six commuters using Mumbai’s suburban trains or found near stations. That year, nearly 2,300 deaths and 2,500 injuries were reported, stemming from various causes including falls from trains, pedestrian accidents on tracks, suicides, electrocutions, and platform falls. Over a thousand fatalities involved individuals crossing tracks, often unaware of approaching trains, while over 500 deaths were attributed to falls from moving trains.

These figures underscore the urgent need for enhanced safety measures on the network, improved infrastructure, and effective crowd management to protect Mumbai's millions of daily rail travelers.
