Three train drivers were among nine killed in crash, Transport Minister Cahit Turhan told reporters on scene.
Nine people were killed and nearly 50 injured in Turkey when a high speed train collided with a locomotive and crashed into a station platform and overpass in an Ankara suburb early on Thursday officials said.
Rescuers worked to free people trapped under the mangled wreckage at Marsandiz train station, 8 km (5 miles) from central Ankara. It was not clear at which speed train and locomotive were travelling when collision occurred. There was light snow on tracks.
The train had been heading from Ankara to central Turkish province of Konya and was not due to stop at Marsandiz. Ankara Governor Vasip Sahin said the locomotive, which lay battered 20 metres (22 yards) further ahead, carried out track inspections.

There were 206 passengers on high speed train, according to state-owned Anadolu news agency, which also reported that the Ankara state prosecutors office had launched an investigation.
Turkey has been developing a network of high-speed rail links during Tayyip Erdogans 16-year-old rule as it looks to ease burden on increasingly congested highways.
