Several passengers were injured after a train collided with stationary carriages at Glasgow Central station.
The train was travelling at 3mph when it struck the carriages
The train from Gourock was pulling into platform 12 at 0916 GMT on Wednesday when the collision happened.
Many passengers who were already standing by the exit doors were thrown to the ground by the force of the impact.
A spokeswoman for First Scotrail said five people suffered minor injuries in the incident.
Among those hurt was a woman who was taken to hospital in a taxi as a precaution. She is understood to have been released from hospital soon after.
One commuter told the BBC Scotland news website that he had heard a loud crunch of metal as the trains collided.
He said: "Passengers were thrown from their seat and those passengers who were standing for a quick exit at the doors where lifted off their feet.
"The train collided with the stationery train in front. Thankfully the moving train was slowing down to a stop at the time. I'd estimate the speed to be just a few miles an hour, less than five.
"I heard a few panicky voices as I was in car three - the last car. The other passengers in the first two cars would have caught most of the impact. I believe several people have cuts and bruises and one person has been taken to hospital."
The commuter claimed that no announcement was made from the driver or guard before the train doors opened to allow people to disembark.
First Scotrail said an investigation into the incident was under way.
