VISAKHAPATNAM-At least 13 people are dead and 50 others have been injured after two trains collided in southeast India Sunday, police officials said. The collision derailed two coaches carrying more than 90 people on the stationary train, the official told Reuters. A preliminary investigation suggests “human error” caused by “overshooting of signal” by the stationary train is what led to the collision, a statement from the country’s railway ministry read. “Out of the 13 people who died, 8 persons have been identified,” M Deepika, superintendent of police for Vizianagaram district, told CNN on Monday. Sunday’s collision comes just four months after a separate train accident in Odisha, where three trains collided, leaving 275 people dead and more than 1,000 injured.
