INDIA AffairsTrendingCab-Cam Audio Exposes Brake Failure: Inside the Digaru Derailment of Kolkata-Sairang Express and India's Kavach Modernization Race
In the early morning hours of November 11, 2026, the Kolkata-Sairang Express (Train No. 13125) suffered a high-speed overshoot and derailment at Digaru railway station in the Kamrup Metropolitan district of Assam. While all 1,200 passengers were confirmed safe thanks to mechanical sand hump barriers, leaked cabin voice recordings revealed the locomotive crew shouting 'Red Signal' as emergency brake applications failed to decelerate the train. The incident has thrust the Ministry of Railways' ₹45,000-crore Kavach 4.0 automated collision-prevention rollout into acute national focus.
