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

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


Sir Topham Hatt 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 make the children's trip special, he is 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 Sir Topham Hatt would be cross. The children have had an exciting ride after all, and Sir Topham Hatt is pleased with Rheneas and calls him a Really Useful Engine.




  • Going by production order, this is the thirteenth episode of the seventh series.
  • According to a SiF interview with Robert Gauld-Galliers and his storyboards, Peter Sam was originally meant to be the main character. Instead of wanting the children's trip to be special, he would have wanted to get their trip over with, so he could return to doing more important work. Open coaches (similar to Ada, Jane and Mabel from the Railway Series) were also set to appear.
  • The teacher is really the storyteller dressed up.
  • The second shot of the episode features unused footage from the sixth series.
  • When released on home video in the UK for the first time, the episode used music from the New Series and was exclusive as it never aired on any of the Nick Jr. airings of Series 8. The UK narration paired with the original music did not come out on home video until The Complete Series 7 was released in 2008. This also applies to What's the Matter with Henry?
  • This is the third episode to use a rendition of the William Tell Overture (Finale); the first being Busy Going Backwards, and the second being Thomas the Jet Engine. However, this is only in the UK version with Mike O'Donnell and Junior Campbell's music and the international versions.


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!
