District Magistrate Rajeev Roshan said another 10 people were injured in the accident in Bihar state. The cause of the accident is being investigated. The Press Trust of India news agency said a rail fracture appeared to have caused the derailment about 30 kilometers (20 miles) north of Patna, the Bihar state capital. Rescue workers and members of India’s disaster management force were working to pull out people trapped in the twisted metal and overturned coaches. Three of the derailed coaches had been cleared of passengers, said Bihar State Deputy Chief Minister Sushil Modi. India’s vast railway system is the world’s third largest but lacks modern signaling and communication systems. Most accidents are blamed on poor maintenance, outdated equipment and human error.
