India's Worst Rail Disaster in Decades Blamed on Electronic Signal System

An error in India's electronic signaling system was blamed for sending a passenger train into a head-on crash with a freight train, causing one of the world's deadliest train crashes in decades. The death toll has been revised to 275, and Prime Minister Narendra Modi has promised the "harshest punishment" for anyone found responsible. The railway official said that the passenger trains were not speeding, and the crash could be a case of sabotage. The electronic interlocking system is designed to keep trains separated, and a detailed investigation will reveal whether the error was human or technical.
