Trevor is a traction engine who works in the Vicarage Orchard.
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 odds jobs and to appear at various events such as steam fairs.
Trevor is very friendly and gets along well with the engines. He is also helpful and ready to give anybody advice. Trevor loves children in particular, especially giving them rides in his cart.
