This is the Tibetan terrier who caused railway chaos after he was found wandering on train tracks as his owner desperately searched for him.
After going missing, Alfie ended up on the train line between Acle and Great Yarmouth and refused to move out of the way of a train as it headed to the coastal resort.
Alfie's persistence on Sunday morning in not moving led to hour-long delays for passengers on the train and other services in the region were cancelled as a result.
MORE: Services cancelled after train forced to follow stubborn dog on trackHis owner, Karin Gibbons, faced her own drama when she had to walk along the train line with railway officials to catch her beloved animal after a day-long search.
Mrs Gibbons was in London with her husband celebrating his 60th birthday when she received a call from a friend who was looking after the seven-year-old dog to say he had gone missing.
Alfie, a rescue dog, has been with Mrs Gibbons for a year now. She said: 'Just the thought of him not being here is terrible. It was the first time he ever went missing.'
The 55-year-old maths teacher at Acle Academy, who lives in Brundall, began searching for him in the dark with no luck.
At first light the mother-of-two began again in earnest, walking and driving for miles between neighbouring villages, enlisting the help of friends, locals and even complete strangers thanks to social media.
As Mrs Gibbons came to the entrance of Acle train station, two women in a car stopped to ask Mrs Gibbons if she had lost a black and white dog.
She recounted the conversation.
'I said yes, that's him and they then told me he was on the train tracks.
'My heart skipped a beat. I thought that was the end of him.'
However it quickly became clear that Alfie was alive and well but he had managed to walk about four miles along the railway line to near Halvergate.
When they arrived a railway official was walking Alfie towards them and told her they had tried to catch him but he was too quick.
Mrs Gibbons said: 'As he came towards me I started calling to him and said I had a treat for him.'
At that moment Mrs Gibbons managed to catch hold of Alfie and bring her ordeal to an end.
She said the community has been amazing, adding: 'We are so grateful to everyone who came and searched the area.'
She added she wanted to apologise to everyone who was caught up in the delays.
She added: 'I feel so sorry for all the people who were delayed because of him.
'I know how frustrating it can be when trains are delayed or cancelled, so it's not a good thing to know that he caused all that.
'I hope it will never happen again.'
