The lines were reopened a short time later but passengers have been warned some services could still be delayed, altered or cancelled.

Phil Campbell, ScotRail head of customer operations, said: "Customers who are delayed by 30 minutes or more are reminded to keep hold of their tickets to claim compensation through our Delay Repay Guarantee.

"We would also take this opportunity to remind people not to trespass anywhere in the rail line as they put themselves and others at risk of serious injury."

British Transport Police have been contacted for comment.
