A TEENAGER is in a critical condition after getting shocked on a rail line. 
The girl, 17, was allegedly trespassing with a group of friends at Sunningdale station on Friday night (June 24) when the incident happened. 
British Transport Police are investigating the incident and said the girl suffered ‘serious’ injuries. 
She is still being treated in hospital, in a critical but stable condition. 
A spokesman for BTP said: “Officers were called to Sunningdale rail station following reports of a person on the tracks.
“The call came into police shortly after midnight on Saturday, 24 June.
“Officers attended and a 17-year-old girl was taken to hospital having suffered electrical burns.
“She remains in hospital in a critical but stable condition.”
On Twitter, BTP London posted the incident update with a warning about trespassing on the railway line. 
They later said it was understood that the teen was attempting to cross the tracks when she was injured. 
Earlier this year, BTP issued a warning about the ‘worrying’ rise in the number of people trespassing on train lines across the country. 
More than 8,000 people trespassed on railways across the UK in 2016 - the highest number since records began.
Network Rail and British Transport Police figures show an 11 per cent rise in incidents to 8,265, compared with 2015.
Some 115 people have been killed on rail tracks over the past five years, with almost half of them aged under 25.
Insp Steve Webster, of the BTP, said: “Every single day we are called to the tracks because a train driver has had to sound their horn or apply their emergency brake In a desperate bid to avoid youths on the line, who then run off, seemingly unaware of the danger they have put themselves in.
“However, we cover thousands of miles of track and we cannot tackle this issue alone. That is why we are urging parents and young people to heed this warning and take a reality check when it comes to trespass. It’s not a game: they are real tracks, with real trains and real-life consequences.”
Network Rail and the police said taking a short cut was the most common reason given for trespassing, followed by thrill-seeking.
A witness said the girl was with a group of youngsters and the community is in shock. 
Another said: “This is a really worrying incident. I think youngsters should be warned about the dangers of going near the train line. I hope the girl makes a full recovery.”
