A woman has told the sex assault trial of former footballer Paul Gascoigne that she did not know it was him at the time.
The 52-year-old is accused of an "unpleasant" sex assault on the service from York to Newcastle in August 2018.
At Teesside Crown Court she said: "He kissed me full on the lips. I was taken aback, it was completely out of the blue.
"I pushed him off to say that’s not ok. I just completely froze.
"It was sloppy and it was not like a peck on the cheek, it was very full on the lips. It was a forceful kiss."
She said another passenger intervened and said it was an assault and not appropriate behaviour.
It was only a few days later, after seeing a TV report, that she realised the man was Mr Gascoigne, she said.
Mr Gascoigne denies sexual assault by touching.
The trial continues.
