“I'm Jack, I'm here to help!"
"More help means more dirt; more dirt means more fun. I'm Alfie!”
―Jack meets Alfie[src]

Alfie is an enthusiastic little excavator, who works for the Sodor Construction Company. He is Jack's best friend.


Thomas & Friends

Alfie works for the Sodor Construction Company; he loves working hard and handles even the toughest of jobs very well with ease.

Alfie helped save a cat and her kittens one day after being teased by Max and Monty about his size. He was also working with Percy at Maithwaite Forest on Halloween night when Kelly told everyone a scary story about a one-eyed truck. Later, he was saved by Byron when he almost sank into a muddy hole. When Max and Monty carelessly crashed into the lightning tree, he, Oliver and Kelly held the tree up while Jack went to fetch the props and the tree was saved. He later helped with the restoration of Great Waterton and helped erect a bandstand in the town.

Alfie helped with the construction of the Harwick Branch Line along with Jack, Oliver, Max and Monty and later attended the line's ceremony.

Later he, Jack, Oliver, Max and Monty were working on Thomas' Branch Line and he, Oliver and Jack helped cleared the branch line at the Rail Under Road Bridge and Signalbox after Max and Monty dumped their loads on the line.


Alfie is a friendly machine who gets on well with his work and never minds getting dirty or mucky during jobs. He always views his work as fun, though he easily gets seasick.
