Edward the Very Useful Engine

"Duck should play with other ducks, 'coz he's no good at pulling trucks! Quack! Quack! Quack! Quack! Hold back! Hold back!"

- The troublesome trucks

Edward the Very Useful Engine, retitled Edward the Really Useful Engine in some American releases, is the twenty-third episode of the sixth season.

Plot
Gordon thinks that Edward is old and should be retired, and the other big engines agree with him, but Percy is concerned about this. He tells his driver  and the Fat Controller about what Gordon said about Edward, who attends to the matter immediately. The Fat Controller arranges for Edward to teach Stepney to run a new loop line, while Duck does Edward's work, but it makes no difference to Gordon. Edward enjoys working with Stepney, but Duck does not enjoy working with the trucks, especially when they hold him back on Gordon's Hill. Duck is stuck on Gordon's line, and it's too late to switch him to the middle line, so the guard tries to flag him down, but Gordon passes by and tries to push Duck up, but it's no good. Gordon's crew sends for Edward to help both engines, and as the strange train sets off and pulls into the station, Gordon feels rather embarrassed and is told off by The Fat Controller for saying rude things about Edward, who has proven to be responsible, reliable and very helpful. The next day, Gordon apologizes to Edward and says that he really is a useful engine. Now there is no more talk about Edward retiring.

Goofs

 * Gordon was only a few minutes behind Duck. So even if Duck had not stopped, Gordon would have either crashed into Duck or would have to slow down to follow him.
 * In the American narration, after Alec Baldwin says, "Sir Topham Hatt spoke severely to Gordon". A voice can be faintly heard saying "Take six".
 * Stepney has Skarloey's whistle sound.
 * Once Gordon stops behind Duck, he could have backed down the hill and then be switched onto the middle line.
 * In the US version, the term "guard" is accidentally used at one point.
 * When Edward buffers up to Gordon a white wire is visible in the windows of the express coach.
 * Duck has Oliver's whistle sound at the beginning.
 * How do Duck, Gordon, and Edward end up at Knapford after descending Gordon's Hill?
 * Percy states that Edward does not have tyres, which is quite wrong because, as stated in Henry and the Express and Steam Roller, railway engines and rolling stock have a steel rim called a tyre to prevent the metal wheels from wearing out and keeping the engine on the rails.
 * In Michael Angelis' remastered narration, the term "freight cars" is used at the beginning.
