There is to be an Engine Rally and Country Show, and Skarloey and Rheneas are to lead the rally. The Thin Controller asks Madge to deliver brushes and soap to make sure the two engines are clean for the event. However, Madge spends too much time making sure they are clean that she does not have time to clean herself leading to mishaps.
Tropes featured in the episode:
- Covered in Mud: Madge ends up with mud all over her bottom half after all the driving she does trying to ensure Skarloey and Rheneas are cleaned. This causes her exhaust pipe to become blocked with mud, causing trouble when it backfires and she sprays mud all over Skarloey and Rheneas.
- End of an Era: This was the final episode to be made as a purely model production. Series 12 would later be a hybrid of CGI and models, whereas Series 13 and onwards were fully CGI.
- Season Finale: Of Series 11.
