Some of the coaches crumpled when they crashed into others, trapping hundreds of people inside. Rescue workers, soldiers and members of India’s disaster management force were on the scene using cutting torches to open the derailed train cars to try to reach those trapped inside. Cranes were deployed to lift the coaches from the tracks. The derailment occurred near Pukhrayan, outside of Kanpur, an industrial city about 250 miles southeast of New Delhi. The Patna-Indore Express train, linking the central Indian city of Indore to the city of Patna to its northeast, completes its 845-mile journey in 27 hours. The more seriously injured were moved to hospitals in Kanpur. It was not immediately clear what caused the coaches to derail.
