A 22 -year -old woman is in a “stable but serious condition”, after she came into contact with the overhead power lines at Hackney Wick rail station on Wednesday night.
A spokeswoman from British Transport Police said the woman suffered burn injuries and was taken to the Royal London Hospital in Whitechapel.
She said “ it is believed the woman fell from the roof of a train” and that “officers are now working to establish how she came to be on the train”.
The London Ambulance Service said the victim was “conscious and breathing” in the ambulance.
The incident was reported to the police at 11.06pm.
Local reports said train users were horrified as the woman who appeared drunk, climbed onto the train before hitting the power lines.
The incident was also reported on twitter.
Candice Tripp wrote: “Brother called; he was at Hackney Wick when a freight train pulled in. A drunk girl climbed up and was standing on the carriage in heels.
“When he shouted at her to get down, she turned and staggered into a cable, got electrocuted, went stiff and fell onto the platform.
“Her clothes were burnt. Like in tatters”.
Her brother, Ty Tripp later tweeted: “she was a mess! I’m freaked out!”.
