mystery surrounds the tragic death of a young woman who fell under a train at an almost-deserted South Yorkshire station.
Two men were initially arrested in connection with the fatality at Mexborough station, but police later decided the incident was not suspicious.
The 28-year-old woman is believed to have missed the last train to her home in Sheffield.
She was later named as Billie Jane Coulton, from Parson Cross. An inquest is expected to be opened in Doncaster next week.
The incident happened just after midnight on Thursday, less than 15 minutes after the last Sheffield-bound train had departed from the two-platform station.
Ms Coulton was hit by an empty passenger train heading back to the depot, say railway police.
At first British Transport Police had to investigate the possibility she may have been pushed onto the track.
But the driver of the train is believed to have provided a statement that enabled police officers to release two suspects, although officers are still studying CCTV footage from the station’s cameras.
Yesterday people waiting for trains at Mexborough were stunned to hear of the death.
Peter Adams, from Mexborough, said: “I hadn’t heard anything about this but it explains why there were remnants of police crime scene tape around the station.
“I asked one of the staff what had happened but no-one seemed to know.
“It’s shocking, it’s a terrible way to go. I can’t think what might have happened but I imagine it’s very lonely here at that time of night.”
One of the staff confirmed Mexborough station is unmanned after 7.30pm and the last train would have left at 11.50pm.
He said: “We weren’t here at the time so we don’t know what was going on. It was back to normal when we arrived for work.”
Yesterday there was still evidence of the station car park having been sealed off to pedestrians.
A police spokesman said: “British Transport Police are currently investigating a fatality at Mexborough railway station, after receiving reports of a woman being struck by a train at eight minutes past midnight on Thursday.
“Officers from BTP and South Yorkshire Police attended the incident, which is currently being treated as non-suspicious.
“Paramedics from the local ambulance service also attended, but the woman, aged 28 and from Sheffield, was pronounced dead at the scene. A file will be prepared for the coroner.
“The train involved was an empty Northern Rail passenger service which was returning to the depot.
“Mexborough station was closed for a period of time overnight while officers worked to determine the circumstances surrounding the incident. The station was re-opened at 4.45am.”
Police sources confirmed two young men had been arrested at the scene but had been released and there would be no charges against them.
