Synopsis
Ol' Wheezy has stopped working. The Logging Locos don't know what to do, which makes Thomas want to help them. First he goes to the diesel works and asks Dart to come with him to help. After Dart's attempt, he gives up and returns to the works. Thomas then asks Den to come and help, but Den says he wouldn't leave without Dart. But Thomas ignores that fact. Back at Misty Island, Dart's attempt also fails. In the end Thomas realises that Den and Dart can manage things when working together.
