A 12-year-old boy has died after suffering serious electrical burns on a railway.
British Transport Police (BTP) said officers and paramedics were called to the tracks on the main Leeds to Doncaster line near South Elmsall, West Yorkshire, following reports of someone on the line.
A spokesman said: "Officers attended alongside paramedics and a 12-year-old boy from the local area was treated by paramedics.
"He was taken to hospital for treatment but despite best efforts, the boy sadly passed away this afternoon in the presence of his family. They are being supported by specially trained officers.
"Inquiries are ongoing to establish how the boy came to be on the tracks but the death is not being treated as suspicious."
He said emergency services were called at about 6.15pm on Monday.
Neighbours have described how they tried to help the boy, who has not been named, as he lay seriously injured on the tracks.
BTP said a file was being prepared for the coroner.
