"She was like bouncing against the train."
After the train moved clear several people jumped down onto the track to help her.
"She had a huge laceration on her leg but she was conscious and we could talk to her. I was straight on the phone to 111.
"She was just lying there and drifting in and out of consciousness."
Clegg was visibly shaken by the event and said the woman was extremely lucky to be alive.
Another witness, Manpreet Singh, said the woman wouldn't listen when she was told not to try and get in through the closed train doors.
"It was very hard to see that, first time in my life," he said.
He imagined the train driver didn't see what was happening.
Azra Eghbali said the woman's leg injuries were severe.
