A number of people have been injured after a train collided with a tractor at a level crossing in Norfolk.
The train, travelling from Norwich to Cambridge, was badly damaged but not derailed.
There were no fatalities in the incident but the tractor and train drivers reportedly suffered serious injuries.
Ten patients were treated at the scene and 10 were taken to hospital, all with non-life-threatening injuries, East of England Ambulance Service said.
Four ambulances, one rapid response vehicle, the Hazardous Area Response Team, three ambulance officers and the East Anglian Air Ambulance attended, a spokesman added.
Passengers reportedly suffered minor injuries such as cuts, bruising and shock.
The conduct of the train driver has been praised. Tom Smith, who appeared to be a passenger on the train, wrote on Twitter: “He did an excellent job to keep everyone safe.”
Images posted to social media by passenger Alex Youngs showed the scene inside the train.
