An 11-year-old boy was identified as smashing a train window near Lancaster station, said police.
A member of the public reported seeing a child throw a rock at a passing train just north of Lancaster earlier this week.
Soon after, train staff reported a smashed outer window skin on the service.
Fast track enquiries by British Transport Police identified an 11-year old boy as being responsible.
Arrangements have been made to speak to him with his parents where officers can explain the dangers of his actions.
Safeguarding and youth offending team referrals will also be submitted, while BTP have been invited by the boy’s school to give a rail safety talk to the children.
