Tender Engines is the twentieth episode ever made in Season 3.
Gordon is impressed when he sees a visitor with two tenders, but becomes depressed when Diesel gloats the Diesels' victory over steam on the mainland. He perks up when he is told that he will never be scrapped on Sodor and that the visitor had two tenders due to the lack of coal and water on the mainland, but Henry is cross and grumbles he deserves two tenders for his work. Duck, planning a trick, coerces Henry into pulling some spare tenders. Henry is delighted, but is less than thrilled when he finds they are all filled with boiler sludge.
- When James first arrives at the coal chute to speak to Gordon, his pony truck is off the rails.
