Kolkata Metro Snag on Blue Line: On the morning of September 8, when thousands of students were hurrying to sit for their first day of the Higher Secondary (HS) examinations, the Kolkata Metro’s Blue Line—the city’s busiest and oldest underground transit corridor—suffered a sudden breakdown.
At approximately 8:20 a.m., a train developed a technical fault near Kavi Nazrul station, leading to chaos during the city’s busiest commuting window. Passengers were evacuated after another train was coupled to tow the faulty rake away. Services between Shahid Khudiram and Tollygunge were suspended for over an hour, forcing students, office-goers, and daily commuters into confusion and panic.
Partial services resumed around 9:25 a.m., and normal operations were restored by 9:54 a.m. But the damage had been done: students heading to examination centers faced uncertainty, and office schedules across the city were thrown off balance.
Stranded Commuters and Exam Anxiety
The timing of the disruption made the situation particularly critical. On an ordinary weekday, a Blue Line snag is enough to inconvenience tens of thousands. But this time, the stakes were higher:
- Students in school uniforms, clutching admit cards, were seen anxiously looking for autos, buses, or app-based cabs. Many feared they would miss their exams if they didn’t find alternatives quickly.
- Parents expressed their frustration, saying the city’s lifeline had collapsed on a day when punctuality mattered most. Some had to pay inflated fares to secure transport for their children.
- Office-goers found themselves in overcrowded buses, while the roads above the metro corridor were clogged with traffic as stranded passengers shifted to surface transport.
The disruption became a reminder of how dependent Kolkata has grown on its metro network, particularly the Blue Line, which ferries lakhs of passengers daily.
Why the Blue Line is Under Strain
The Blue Line, running from Dakshineswar to Kavi Subhash, is the backbone of Kolkata’s metro system. But in recent months, it has been operating under severe strain.
- Closure of Kavi Subhash station: Since late July, the terminal station has been closed after cracks were detected, forcing trains to terminate at Shahid Khudiram. This has overloaded Shahid Khudiram station, which was never designed to handle terminal-level crowds.
- Rising passenger numbers: With the opening of new corridors such as the Green Line (East–West) and Yellow Line (Airport extension), more passengers now interchange onto the Blue Line at busy junctions like Esplanade and Sealdah. Daily footfall on the Blue Line has spiked beyond expectations.
- Overcrowding and train frequency issues: Attempts to add more services have led to scheduling complications. Overcrowding has also triggered safety incidents, with train doors unable to close properly during rush hours.

Commuter Voices and Ground Reality
The snag caused visible distress across stations. Eyewitnesses reported:
- Long queues forming at ticket counters and security checkpoints, especially at Shahid Khudiram.
- Crowds spilling out onto the streets, where autos and taxis quickly hiked fares.
- Social media platforms filling up with videos of suffocatingly packed trains and angry commuters questioning the metro’s reliability.
For students, the timing was especially cruel. One anxious examinee was quoted by her parents as saying she feared her academic career would be jeopardized if she missed the exam due to transport failure.
Kolkata Metro Snag on Blue Line: The Technical and Operational Gaps
The breakdown highlighted deeper issues plaguing the Blue Line:
- Ageing infrastructure – The Blue Line, India’s oldest metro corridor, began operations in 1984. Decades of heavy usage have left many rakes outdated and prone to technical faults.
- Maintenance challenges – With Kavi Subhash station shut, the pressure has shifted to fewer depots and stabling facilities, making maintenance cycles harder to manage.
- Inadequate crowd control – Stations like Shahid Khudiram are overwhelmed during peak hours, with insufficient staffing and limited space to manage sudden surges.
Urban transport experts note that without better scheduling, modernization of rakes, and expansion of support infrastructure, such disruptions will likely recur.
Ripple Effects Beyond the Metro
The disruption also affected the surface transport network:
- Buses on routes parallel to the Blue Line saw a sudden surge in ridership, leading to overcrowding and delays.
- App-based taxis surged in price due to high demand, forcing many commuters to pay more than double the normal fare.
- Road congestion worsened in key areas like Garia, Tollygunge, and Rashbehari as thousands of passengers spilled onto the streets.
This incident demonstrated the city’s growing dependence on the metro as the backbone of its daily commute. When that backbone falters, the entire urban mobility system begins to collapse.
Authorities Respond, But Questions Remain
Metro authorities worked quickly to restore services, towing the faulty rake and resuming full operations within a couple of hours. However, the incident has raised serious questions:
- Could the technical fault have been avoided with better preventive maintenance?
- Should metro authorities have a stronger contingency plan for student exam days, when disruptions carry higher consequences?
- Are overcrowded Blue Line services reaching a breaking point where safety is at risk?
The answers lie in more investment, better planning, and timely communication with commuters.
Learning from Other Metro Systems
Other metro systems in India—such as Delhi Metro and Bengaluru Metro—have faced similar challenges but managed them through technology and planning. Features like:
- Real-time apps that alert commuters to breakdowns.
- Integrated feeder bus services to handle spillover traffic.
- Dedicated student helpdesks during exam season.
If Kolkata Metro adopts similar solutions, it could prevent exam-day fiascos and restore public confidence.
For a comparison, see Delhi Metro Rail Corporation which outlines its operational protocols.
The Way Forward
The Blue Line’s struggles highlight the urgent need for:
- Upgrading rolling stock – Replacing older rakes with modern, fault-resistant models.
- Strengthening alternative stations – Expanding Shahid Khudiram and other stations to manage terminal-level crowds.
- Crowd and safety management – More staff, better platform crowding controls, and digital ticketing to reduce delays.
- Contingency services – Tying up with bus operators and app-based cabs to ensure exam-day and emergency backups.
These steps could transform the Blue Line back into the dependable lifeline that commuters once trusted.
Conclusion: A Wake-Up Call for Kolkata Metro
The September 8 breakdown was not just a technical glitch—it was a warning sign. A city that depends so heavily on its metro cannot afford repeated failures, especially during high-stakes moments like student examinations.
The incident underscores the need for a holistic overhaul of Kolkata’s metro operations: modern infrastructure, robust contingency planning, and commuter-first thinking. Until then, commuters will continue to face uncertainty every time they step onto the Blue Line.
