Saved from Scrap - S2.E4

In a lonely, rusty Scrapyard is poor Trevor the Traction Engine, who is ready to be broken up. He is feeling sorry for himself because he feels that he's too old-fashioned to be Useful. Edward finds Trevor's situation to be a tremendous shame, and is determined to find someone to buy Trevor and save him, but who would "have room for a Traction Engine at home?"
