A woman who fell onto the tracks in front of an oncoming train has thanked the soldier that rushed to saved her life.
Soldier Billy McPhail was on the Good Morning Britain sofa recounting his heroic actions when he got the surprise.
Mr McPhail said he was "acting in the moment" after he heard "a loud thud" and realised what had happened.
I heard the horn of the train sound ... and knew that there was a train coming.
People obviously were screaming and shouting and hesitating, but no one was getting down to help.
So I thought, 'I've got to spring into action - if I don't then this lady is obviously going to lose her life'.
The 26 year old said he had spoken to the woman's husband since the rescue took place and although he knew she had surgery on her broken ankle, he had been unable to speak to her.
But GMB had a surprise for Mr McPhail, a live message from Barbara Smith - the woman he saved.
Speaking from her home in Kent with her leg bandaged, Mrs Smith thanked the soldier for coming to her rescue.
"I'd just like to say thank you very much for saving my life ... if it hadn't been for his quick actions I wouldn't be here to tell the tale," she said.
"No worries," he answered. "I just think if my mum was still alive then hopefully someone would have done that for me".
When GMB's Ben Shephard thanked Mr Phail for coming on the show calling him "an absolute hero," he said humbly, "I'm not but thank you".
