"My master would send us from farm to farm. We'd thresh corn, haul logs and did lots of other work. The children loved to see us. Oh yes, I like children."
— Trevor, Saved from Scrap, second season




  • Builder: William Foster & Co.
  • Built: 1927

Trevor is a dark green traction engine that resides at the Wellsworth Vicarage Orchard. He is owned by the Vicar of Wellsworth and driven by Jem Cole.

Bio in the Railway Series

Trevor used to work on farms doing odd jobs like threshing corn and sawing timber, but his owner thought he was old-fashioned and sent him to the scrapyard. Edward luckily befriended him and convinced Rev. Charles Laxey to purchase him. Trevor now lives in the Wellsworth vicarage orchard, but is often borrowed by his driver Jem Cole to do odd jobs and to appear at various events such as steam fairs.

Bio in the Television Series

As in the Railway Series, Edward and Jem Cole saved Trevor from scrap.

Sometime after that, Trevor soon had no work to do, so Edward took him to Thomas' junction, where Thomas took him to work at Knapford Harbour. At the end of the day, Thomas took Trevor back to the junction and tells him that he may visit him sometime and that the vicar now has work for him to do in the orchard, but may be needed at the harbour again someday.

Edward and Trevor once helped the vicar organise a garden party to raise money for a seaside trip for underprivileged children.

Later on, Trevor has been seen working in other places such as Farmer McColl's Field and the Sodor Airport.

According to a magazine article, he sometimes works on Farmer Trotter's Pig Farm.

He was an attraction at the Sodor Steam Fair and was later seen at a fair at Maithwaite.

In the twentieth season, when one of Farmer McColl's cows got stuck under the bridge at the Watermill, Trevor helped lift it out.


Trevor is incredibly cheerful, kind, and benevolent, and gets along well with nearly everyone. He enjoys basking in the sunshine or dozing in his shed, but easily grows bored and unhappy if he doesn't have much company, or enough work to do. Trevor is particularly fond of children, and loves giving them rides whenever he gets the chance.


Trevor is based on a William Foster & Co. eight-ton traction engine built in 1927 named Fiery Elias that was owned by the Reverend W. Awdry's friend, the Reverend Teddy Boston. He also owned the steam roller that became George and Buster's basis.


In Edward the Blue Engine, Trevor was painted black all over with gold boiler bands and a gold chimney cap. In Thomas and the Twins and Thomas and the Missing Christmas Tree, he was painted green with gold boiler bands and a gold chimney cap.

Throughout the television series, Trevor is always painted dark green with red lining and wheels, a black smokebox and gold boiler bands.


He was also likely to appear in the cancelled episode Isobella Gets Steamed.

"I'm Trevor, they're going to break me up next week."
"What a shame!" said Edward.
"My driver says I only need some paint, Brasso and oil to be as good as new," Trevor went on sadly. "But it's no good. My master doesn't want me. I suppose its because I'm old fashioned."
Edward snorted indignantly. "People say I'm old fashioned. But I don't care. The Fat Controller says I'm a really useful engine."
"My driver says I'm useful too," replied Trevor. "I sometimes feel ill, but I don't give up like these tractors. I struggle on and finish the job. I've never broken down in my life!" he ended proudly.
