Danya Arnold came face-to-face with the suspect who was running through the carriage during the frenzy.
"I just said, ‘Please don’t kill me," she told the Mirror.
"Something shifted in his face and he just carried on. He said: ‘The devil is not going to win.'"
Two people were initially arrested but the British Transport Police said on Sunday afternoon that a 32-year-old man from Peterborough is now the sole suspect.
He remains under investigation on suspicion of attempted murder.
The other man, 35, from London, t has been released without charge.
Officers also recovered a knife at the scene.
Five casualties have since been discharged from hospital and one remains in a life-threatening condition, who is confirmed to be a member of LNER rail staff.
One eye witness, Olly Foster, said he heard people screaming "run, run, there's a guy literally stabbing everyone."
Olly, who was a passenegr on board said he initially believed it might have been a Halloween-related prank.
He recalled people surging through the carriage and that when he looked down at his own hand, it was "covered in blood" and there was "blood all over the chair" that he had been leaning on.

An older man "blocked" the attacker from stabbing a younger girl, leaving him with a gash on his head and neck, Olly said.
Another passenger, named Gavin, told Sky News that he saw a victim moving through his carriage saying: "They've got a knife, I've been stabbed."
"They were making their way through the carriage to get away from the suspects. They were extremely bloodied," he added.
He says by the time the train stopped, "they were basically on the floor".
"That person ended up collapsing on the floor. They were taken to an ambulance pretty much straight away," he said.
When it was finally safe to leave the train Gavin said he saw "The armed police were pointing to the suspect as we came off the train.
London Underground worker Dean McFarlane said that he saw multiple people running down the platform bleeding, with one man in a white shirt "completely covered in blood".
He said he grabbed people and told them to leave the station, and tried to assist passengers who he believed were having panic attacks.
Another witness Thomas McLachlan said "there were many heroes" including good samaritans on hand to help casualties.
"One other man who I saw, one of the injured people getting off the train, had been slashed in the face," he told the BBC.
"From the account that I heard, he was trying to protect a young girl from being attacked by the attacker, and he took that injury to the face out of protection for her – that’s some real selflessness, right there."
