The local governor Vasip Sahin has said a Turkish high speed train collided with another locomotive and crashed into an overpass at a train station in Ankara on Thursday, killing four people and injuring forty-three.
Officials say Turkish high speed train crash was caused by collision with a locomotive which carries out track inspections.
Video footage showed emergency workers at the scene, working to rescue people from carriages trapped beneath the mangled metal wreckage of an overpass at the Marsandiz train station, to the west of Ankara.
The accident occurred around 6:30 am (0330 GMT) as the train was traveling between Ankara and the central Turkish province of Konya. The Marsandiz station is around 8 km from the main Ankara train station.
