NEW DELHI: Thirteen coaches of an express train derailed in northern India early Friday throwing sleeping passengers from their seats in a new disaster that left three dead and nine injured. The Vasco Da Gama Express flipped off the tracks in thick fog soon after leaving Manikpur station in Uttar Pradesh state, police said. The train was heading for the Bihar state capital of Patna when the accident took place at 4:15 a.m. (2245 GMT) when most travelers were asleep. The dead included a six-year-old boy and his father. Local Police Chief Pratap Gopendra Singh said the blanket of fog over the region hampered the rescue operation. He said a fractured rail was suspected to have caused the accident. Traffic on the main rail link was disrupted for several hours.
