“Oh, no! This line is closed for repairs! Bust my buffers!”

Rheneas and the Roller Coaster is the twelfth episode of the seventh series.


The Fat Controller has given Rheneas the task of taking some school children to the mountains, but Rheneas is worried that he might not be able to make the trip memorable. Rheneas arrives at the station asking Rusty how he can make the children's day special. Rusty tells him that he knows the mountains better, but Rheneas is not sure his best would be exciting.

Rheneas' driver shows the children the Castle, the Valley and the Viaduct during the trip. The children are surprised, but Rheneas considers the locations boring and longs for more excitement. Meanwhile, Rusty is inspecting some track on the Rocky Ridge Line after heavy rain washed the ground and made the track bumpy.

While Rheneas is still trying to think of something that would make the children's trip special, he does not know the linesman has forgotten to switch the points. This leads to him being diverted onto the dangerous line, sending him on a roller coaster-like ride down the mountain. The children are very excited and have a wonderful time, completely oblivious to the fact that Rheneas is a runaway. The teacher does not share their enthusiasm and finds herself nauseated. Rheneas makes it to the station safely in time for the children's tea, but is worried that the Fat Controller would be cross. The children have had an exciting ride after all, and the Fat Controller is pleased with Rheneas and calls him a Really Useful Engine.





  • At the beginning of the episode, Rheneas' eyes are wonky.
  • Throughout the episode, the Fat Controller's hat is covered in dust.
  • Before Rheneas leaves the sheds, his dome is dented.
  • When Rheneas talks to Rusty, his eyes are wonky, and at one point, they did not move at the same time.
  • When Rheneas passes the points, both he and his carriage bounce.
  • Despite saying the tracks were bumpy, Rheneas hardly even makes a single bump.
  • When the teacher says "Just in time for tea", her hair is stained.
  • In the close-up shot of the points switched the wrong way, a steam platform is visible.


Rheneas: How can I make the children's day really special?
Rusty: You know the mountains better than any engine.

Children: [after Rheneas has stopped from his wild ride] It was the best school trip ever!
The Fat Controller: You gave the children a wonderful trip. You really are a very useful engine.
Rheneas: Oh, thank you, sir!
