The Kolkata-Sairang Express derailed at Digaru station in Assam on 11 November after hitting barricades while entering the station. The incident led to the engine and at least five coaches going off the tracks. The train was entering Digaru station at around 6:54 am to allow another train to pass when the derailment occurred. Videos from the locomotive's cabin captured the moments before the incident, with a voice heard saying, “Nothing is working…” Northeast Frontier Railway said the loco pilot could not control the train's speed. However, footage from the cabin appeared to suggest a possible emergency brake failure. Whether a brake malfunction caused the derailment remained unconfirmed at the time of publishing. Several passengers reportedly sustained minor injuries. Railway officials launched rescue operations and arranged an alternative train for those affected. The incident has also brought attention to railway safety and locomotive braking systems. According to Railway Ministry data, derailments accounted for 24 of India's 31 major train accidents in 2024-25. Indian Railways requires regular checks of locomotive brakes, including emergency braking systems. The cause of the Kolkata-Sairang Express derailment remained under investigation at the time of publishing.
