|Tenders and Trouble|
|Season Three, Episode unknown|
After a landslide, Bert (who has only just finished being rebuilt) has to go and help. However, his new tender isn't quite finished, but the workmen say they have a spare so he uses that one. It turns out the tender belongs to Jock, a brand new engine, who would be introduced at the end of the episode.
- This episode would have marked the first appearance of Frank and Jock, but instead they don't appear until Season 5.
- The Railway Series story, "Jock" would've been referenced at the end of the episode.
- WildNorWester as the Narrator, Douglas, Bert, Rex, Mike, Jock, Frank and Mr. Fergus Duncan
