A railway line had to close after a train derailed when it hit a herd of cows that had strayed onto the track.
Southeastern Trains said the incident happened between the villages of Wye and Chilham in Kent, involving a train travelling from Ashford to Canterbury.
Around 70 passengers who were on board at the time were evacuated by emergency services, with no reports of any injuries.
Two carriages were derailed but remained upright, Kent Fire and Rescue Service said.
Passenger Jonathan Calder tweeted a picture from the train which was derailed near Olantigh Road, showing the carriage in front of his at an angle, with the right-hand side of it clearly no longer on the rails.
He wrote: "Everyone is fine but this train is going nowhere. Front coach derailed."

Southeastern said there will be a bus replacement in place all day.

The operator tweeted: "Following yesterday's derailment at #Chilham, buses will replace trains between Ashford Int and Ramsgate via Canterbury West all day today.
Where possible we advise travelling to Canterbury East for an onward train to Ashford Int/Faversham for a HS1 train at no extra cost."
