A teenage boy and girl from the same secondary school died last night after being hit by a train just outside a station in a suspected suicide pact.

Charleigh Disbrey, 15, and Mert Karaoglan, 18, pupils at Hertswood Academy in Borehamwood, were found on the tracks around 200 yards from Elstree and Borehamwood station in Hertfordshire.

Charleigh, known as CJ, dreamed of being a professional musician – and had recorded herself singing Titanium by David Guetta in a final video posted on YouTube five days before she died.

Paramedics were called at 9pm last night to the scene where Charleigh and Mert were hit by the cross-London First Capital Connect train from St Albans, Hertfordshire, to Sutton, south London.

The train was travelling at speeds of up to 90mph when it hit the two teenagers, who were in years 10 and 13 at school.

Charleigh, who only turned 15 last Friday, said she performed in school assemblies and had auditioned for Sky talent show Must Be The Music as well as ITV programme Britain’s Got Talent.

She said online: ‘Whenever it is possible, I have been the lead part in two musical performances at school. I am soon going to be recording my own album at my school recording studio.

Mert, who was in the sixth form, was studying A-levels in Media, Photography and Business.

He wrote last month that he hoped to attend Hertfordshire University to study visual effects and would be working on his film-making through the summer months.

He said: ‘I am currently studying photography as an A-Level subject within Hertswood School, and the reason why I have taken that subject is because I have a big interest within photography and how we can simply document our lives by taking photographs and how technology has improved over the years to take photography as a subject or a hobby to new levels.’
