Human error may have led to the massive train tragedy that killed 21 and injured over 90 in Uttar Pradesh’s Muzaffarnagar district on Saturday, according to locals. Thirteen coaches of the high-speed Puri-Haridwar Utkal Express derailed around 5:45 pm; two crashed into a residential area, ramming a house and a college. Railway Minister Suresh Prabhu has ordered an inquiry into the accident, saying strict action will be taken in case of lapses. The state police said that the Anti- Terrorist Squad (ATS) will “investigate into the causes of the accident” and look at any aspect of “sabotage”. Jagat Ram, one of the residents of the house that was damaged when the train crashed into it, told NDTV that parts of the rail track in the area were being repaired for the last two days. Locals suspect that the driver of the Utkal Express was not informed about the repair work. “Two other trains that passed through the area before this train had slowed down. This one did not. It came really fast and rammed into the house,” Jagat Ram said.
