The body of a carer, who had attended an all night outdoor rave, was spotted lying across railway tracks by a group of morning runners, an inquest heard.

Hayley Prett, 40, was found dead on the line between Folkestone and Dover on Sunday, September 30 last year after spending the night partying with her friends.

Police and ambulance crews, including the Hazardous Area Response Team, were called to the scene at Folkestone Warren near Capel-le-Ferne where an investigation into her death was launched by British Transport Police (BTP).

At an inquest into her death today, the court heard how Miss Prett, of Sandgate High Street, died after taking a mix of drugs, and ended up on a live rail track which electrocuted her.

Assistant coronor Katrina Hepburn heard evidence from BTP officer DC Mark Connor at today's hearing at Archbishops Palace in Maidstone.

He explained that Miss Prett had been to an annual event known as the End of Summer Party, or rave, which began on the Saturday night and went on until the Sunday morning.

Police previously confirmed they had attended a gathering of about 30 people at the Warren, but no breaches of the peace were reported at the event on Saturday evening and no police action was taken.

DC Connor said: "It normally attracts people from the Folkestone and Dover areas. She had been to that party before."

Taking the coroner through the events leading up to her death, DC Connor told how Miss Prett had been seen looking 'happy' and drinking gin and lemonade.

But then at one stage in the early hours, she was discovered lying half way in a bush, where she was heard asking for help and shouting 'get off'. Concerned friends called an ambulance, but Miss Prett reportedly then stood up and went back towards the party. The ambulance did not attend at this time.

At around 8.30am, she was then spotted naked by another party-goer near the tracks in the Warren 'screaming in a carefree manner', bending down, dropping to her knees and waving her arms. The witness left the area, as he felt he was intruding what he described as a 'ritual'.

Miss Prett was next seen by a group of morning runners around 10am, when they are said to have first spotted something on tracks, but later identified it to be a body and reported it to police.

Her death was initially treated as suspicious due to the nature of the incident and circumstances, but was reclassified to non-suspicious after her belongings were found elsewhere on the Warren.

Miss Prett's clothes, including her jumpsuit and her handbag with her mobile phone, were found on a path leading down to the railway line. DC Connor said no CCTV was available.

The coroner concluded Miss Prett's death was drug related.

A toxicity report showed Miss Prett had used MDMA, or ecstasy, and was found to have 4.2mg of the drug per litre in her system, which were considered to be 'excessive' levels. The court was told Miss Prett occasionally took part in recreational drug use.

Amphetamines and the drug ketamine were also found in her system, and the mixed side effects of which were read out in court including highs and lows.

Reading evidence, the coroner said: "It is not possible to determine the exact effect Miss Prett was experiencing at the time of death."

A pathology report revealed that an examination of Miss Prett's body showed she had charred burn lines to her back, buttocks and elbow from electrocution.

Third party involvement was ruled out, but the coroner added that the exact circumstances as to how or why Miss Prett ended up on the line were difficult to determine.

She noted that 'at the level they were at', the mix of drugs would have affected Miss Prett, but in her conclusion said there was no evidence of Miss Prett intending to take her life.

Speaking to Miss Prett's family who were present in court, the coroner added: "Thank you for attending and please accept my sincere condolences."
