Thomas & Friends: Season 6, Episode 23

6 - 23: Edward the Very Useful Engine

The big engines believe Edward has used up all of his steam and should be retired. Percy is concerned and tells the Fat Controller about it. Edward is sent to run a loop line with Stepney, while Duck has to deal with Edward's Troublesome Trucks. They become too much for him and he slowly stalls himself and Gordon. Only Edward can rescue them now.
