POLICE are on the hunt for offenders after a high-speed train struck a lorry tyre deliberately placed on the main line between Menheniot and Liskeard.
A First Great Western train bound from Paddington to Penzance hit the tyre at about 1.20pm on Sunday, December 22, and though no one was hurt the locomotive was damaged and the service disrupted.
Detective Constable Dave Bailey from the British Transport Police, who is investigating the incident, said it could have had tragic consequences and the culprits needed to be caught.
"The driver of First Great Western's 0857 London Paddington to Penzance service reported striking the lorry tyre which was on the line," he said. "He brought the train to a halt and, although the train suffered some damage he was able to continue after a delay of around 30 minutes.
"Thankfully no one was injured, but this could have resulted in a much more serious incident. Placing objects on the railway line is an extremely dangerous act.
"It's only through good fortune that no one was harmed and it is vital that we trace whoever is responsible for this foolish act."
Anyone with information is being asked to call British Transport Police on 0800 405040. They can also make an anonymous report to the charity Crimestoppers on 0800 555111.
The incident reference number is 234 of December 22.
