Turkish media says two people were injured after a train hit a construction vehicle on an Istanbul suburban route.
The train crashed into a vehicle laying out the power line.
Photographs from the scene showed the front of the electricity construction car destroyed.
The agency said that two people stuck on the train were rescued. There was no information on their conditions.
In December, a high-speed train hit a railway engine and crashed into a pedestrian overpass at a station in the Turkish capital Ankara on Thursday, killing nine people and injuring dozens of others.
