VIENNA, April 15 (Xinhua) -- At least nine people were injured in a train-crash accident on Saturday in Vienna, police told media.

Two trains crashed in Vienna Meidling station, one of the main train station of the city, in the afternoon. A witness told local media that the accident took place in the station when both trains ran in low speed.

At least nine were injured in the crash, but the drivers of the two trains were not injured. Some of the passengers have been sent to hospital in Vienna, while many of others got out of the train themselves.
