Freight train 'could have derailed' in Rochester
A freight train could have derailed when it struck a fence post that was placed on a railway line, British Transport Police have said.
The incident, near Buckland Road bridge in Rochester, Kent, was reported to the force at about 13:30 GMT on Wednesday.
Sgt Andrew Herbert said nobody was injured, but added that "we may not be so fortunate if this happens again".
He appealed for anyone with information about the incident to come forward and speak to British Transport Police.
"I cannot emphasise enough the dangers associated with this type of crime, and it is vital that we find those responsible," Sgt Herbert said.
"Thankfully this time, through luck, no-one was injured, but we may not be so fortunate if this happens again.
"Trains travel at high speeds and there is a very real risk when they strike objects on the track that they could be derailed."
