SHOCKED families travelling to the seaside on one of the hottest days of the year have told how hundreds of drunken youths “terrorised” passengers by taunting commuters, vomiting and smoking in carriages.

Well over a thousand teens from across Glasgow are reported to have filled trains as they made their way to Troon for a booze-filled bank holiday at the beach on Monday.

But passengers were left traumatised after crowds of rowdy youngsters boarded mid-morning trains to the Ayrshire coast laden with masses of alcohol, and proceeded to smoke, vomit and become aggressive with fellow passengers, according to witnesses.

Lucy Mathers had returned to her family home in Neilston from Amsterdam, where she now lives, to spend the bank holiday weekend with her family.

But the 30-year-old’s decision to take her five-year-old niece to Ayr ended in disaster when the tot was left unable to sleep and suffering nightmares after the witnessing the scenes on the train.

Ms Mathers told the Evening Times: “You could see there were alcohol bottles down their tops. A woman told me she didn’t understand how they could get it on board if they were being checked but I didn’t see any bag checks take place.

“There were maybe 100 teenagers at Paisley station. They were all pretty drunk and they were falling all over us, it was like a stampede as they were getting on the train.

“They were just so obnoxious. A girl behind us was sick and one of them was arguing with a mum because they kept nudging her pram with a baby inside, who was maybe one-year-old.”

Ms Mathers was told by a teenage girl the event had been co-ordinated on Facebook, with a page set up telling the underage children which stations where unmanned by police and rail officials, allowing them to bring their alcohol on board the train without issue.

While police boarded the train at Irvine, Ms Mathers said bag searches were “pointless” as the alcohol was hidden in the youths’ clothing.

Their anti-social behaviour became so frightening for Ms Mathers and her niece she decided to leave the train and take a taxi to Ayr beach – and, she says, she wasn’t the only passenger to do so.

She added: “A family had to leave the train because their kid, who was maybe five or six-years-old, had alcohol spilled on him and the kid left shaking and crying – so many kids were crying, it was quite scary.

“They started smoking on the train, so we tried to open the windows but they were all locked.

“There were no staff, no police and it was so packed we had nowhere to go. All of this was at 11.30 in the morning.”

Ms Mathers’ niece, who she described as always chatty and bubbly, was stunned into silence by the youths’ dangerous behaviour.

Her aunt told how the youngster witnessed teens swinging glass bottles in the air and dropping their cigarettes onto the alcohol-soaked floor – a moment Ms Mathers described as “pretty terrifying”.

After spending their day at Ayr beach, the duo returned to the train to make the journey home to Neilston, but the tot was so frightened, Ms Mathers was forced to contact her parents for a lift.

“She was terrified to go on the train back,” Ms Mathers added.

“We got there about four and signal faults had meant all the trains were cancelled, but we were able to get to Kilmarnock and then I got my dad to pick us up – I didn’t want to put her through that again.

“I don’t understand why there were no police or staff at some of the stations or on the train. I don’t think my niece should have been subjected to this. She was scared to go to sleep last night, she had a bad dream about it.”

Douglas Neill was travelling from Johnstone to Gourock and back for the day.

He said: “At the end of the day, there was absolutely no support from anybody on the train.

“The conditions were so hot and crowded, and after waiting for several hours, I decided to take matters into my own hands and got a taxi, which cost £35.

“This is the second bank holiday that the train line has been a shambles and lasted into the following day, which just isn’t good enough.

“Kids were left with nothing, no support at all and no railway staff to be seen. The police did a great job but the rail staff should be ashamed.

“I was offered a refund but it’s not about the money – it’s only £3 or so for the ticket – it’s the inconvenience. The Transport Minister should be answering questions about all of this. It is disgraceful.”

Witnesses described police closing the gates at Troon station on Monday evening in a bid to limit the amount of teens boarding each train prior to cancellations throughout the area.

The chaos resulted in at least six arrests, one of a 15-year-old, while a 16-year-old boy was rushed to Crosshouse Hospital after a large fight broke out on the beach on Sunday.

Around 50 police offices from Ayrshire, backed by British Transport Police, the Red Cross and the Scottish Ambulance Service were drafted in to cope with the estimated 1500 young people at the site.

ScotRail Alliance said a multi-agency approach was taken to tackle anti-social behaviour on trains in the area. A spokesman said: “Anti-social behaviour at our stations and on-board our trains is completely unacceptable, and we will continue to work with the British Transport Police and other agencies to tackle this.

“The safety of our customers and employees is our priority and everyone should be able to go about their journey in peace.”

The Safer Shores initiative, which was kick started by South Ayrshire Community Safety Partnership, was put in place to crackdown on incidents at the area’s beaches, which have been a hotspot for anti-social youth behaviour in recent years.

It aims to ensure a high visibility police presence on the beach during the summer months.

Chief Inspector Davie Gray, from British Transport Police, said: “During the weekend, officers from BTP worked long hours, alongside Police Scotland to deter incidents and to prevent trouble makers from drinking alcohol. Alcohol bans were in place, and where police officers identified youngsters with alcohol it was confiscated. “We know that some services were disrupted due to signalling issues, however we worked closely with ScotRail to ensure passengers got home safely, at times escorting train servicesWe’ll continue to work closely with our partners to ensure that these events are policed robustly and that crime and anti-social behaviour is prevented.”
