Nine people were injured after two trains collided at a railway platform in Plymouth.
No-one is believed to be trapped following the incident, which happened on platform six at Plymouth railway station.
Four fire engines attended the incident which is described as "on-going", according to Devon and Somerset Fire and Rescue Service.
Dominic Parnell, 33, said the train he was travelling on collided with one in front.

"Of course, most people were stood up waiting to alight and were thrown forward.
"No one appeared to be injured in my immediate area".
