Rheneas has trouble when he neglects undergoing regular maintenance; and Percy has a problem when he helps Thomas with a problem.
This episode provides the following Tropes:
- Kick the Dog: Diesel does nothing more than insult Percy while he's down.
- Recycled Plot:
- Rheneas' story is adapted from "Gallant Old Engine" with the railway actually being successful instead;
- Percy's story is adapted from "Percy's Promise," but since helicopters weren't around in the 30s, Harold's part is omitted.
