TEENAGE thugs smashed emergency glass on a train in what a commuter described as “a callous act of vandalism”.

The incident happened on an Ardrossan Harbour to Glasgow Central ScotRail service.

A group of teenage girls boarded the train at Ardrossan South Beach Station shortly before 5.30pm on Thursday, October 18.

One of the girls then used her arm to smash a glass panel which was covering an emergency lever beside the train doors. She then smashed the glass of a second emergency lever located at the other end of the carriage.

The girls, who are thought to be around 13-15, exited the train at Saltcoats and were observed walking up Raise Street.

One outraged commuter described the incident to the Herald as “a callous act of vandalism”.

The 24-year-old, who wished to remain anonymous, added: “There were about six of them and they smashed both of the glass panels. There was glass everywhere. It’s a shoddy way to behave.”

The incident was reported to British Transport Police.

A ScotRail spokesperson said: “Vandalism and antisocial behaviour on Scotland’s railway is completely unacceptable, and we will work with the British Transport Police to clamp down on this unacceptable behaviour.”

A spokesman for British Transport Police added: “We would encourage the public and staff to report criminal damage or ASB problems.”
