Rosie's Carnival Special
Rosie's Funfair Special, retitled Rosie's Carnival Special in American releases, is the third episode of the twelfth season.
Rosie and Emily are pulling a train for a fair, but Rosie wants to pull it alone. When Rosie reaches Brendam Docks she tries to pull the train, but the tension caused by Emily coupled up at the other end snaps a coupling and Rosie leaves with only half the train. More trucks come loose during the journey, causing problems for Bertie, Stepney, and Emily. When caught by the Fat Controller, Rosie fetches Rocky to repair the damage and she and Emily pull the train back together and deliver it to the Fair grounds.

- The sugar is just dumped into a truck instead of being loaded in crates.
- In the American narration, Stepney says "Oh my!", but his mouth doesn't match the words.
- In real life, Stepney would have been pushed backwards by the collision.
- How was Bertie able to see the coconut truck if it was still around the bend and Stepney see the sugar truck if it was on another line behind bushes?
- In real life, Emily probably would have been derailed by the collision.
- The ferris wheel's benches would not have been so heavy that Rocky was needed to lift them.
- Stepney has Thomas' whistle sound.

- After the sugar truck hits Stepney, he does not look even remotely dirty.
- No explanation is given as to why Stepney was in a siding.
- The side of the sugar truck is upside down.

- When the camera zooms out after the coconut truck crashes into the crossing, Bertie disappears.
- Bertie has Caroline's horn sound.
- Nothing is said about Bertie and Stepney after their accidents.
