A passenger train crashed head-on into another train in northwestern Turkey on Sunday, killing one of the engine drivers and injuring at least seven other people, an official said. The Governor of Bilecik, some 250 miles (400 kilometers) south of Istanbul said the accident was caused by an electrical fault that led to a signal failure. The train went through a signal where it should have halted and slammed into another train that was stopped on the line. One driver was killed. The injured included two rail personnel and at least five passengers, said Bilecik"s governor, Musa Colak. The trains were traveling in opposite directions between Istanbul and the city of Eskisehir.
