About and Inspiration

The series will be about most characters introduced between the fifth and seventeenth seasons of the original Thomas the Tank Engines and Friends series that have no specific background or no established role in the series. It will also expand upon one-offs like Billy and Derek.

Inspiration came from the fact that the writer, MainLineEngines felt that these engines could have a lot of potential if introduced as real engines who worked on the British Railways and if they could have a proper role on Sodor. Because he felt introducing so many characters in a short time in the original series, Adventures on Rails, he created this series specifically for that purpose. It was also decided that one reason for so many engines would be a railway expansion, with several new projects such as an extension from Arlesburgh to Harwick, reopening of the Norramby Branch Line, and extension from Ffarquhar to Ulfstead on Thomas' Branch Line. It will also see more locations such as the Sodor Suspension Bridge, Great Waterton, Sodor Airport, Ulfstead Castle, just to name a couple. Each and every one of these engines will have a touching backstory that will make them interesting and also they will actually have a job that will make them Really Useful Engines.


Some of the characters featured in this series appeared in Thomas and the Avalanche. The Writer's original intent was to eventually include everything that had been introduced in the series. However, the plan was cancelled due to the changing standards of writing and the difficulty in integrating everything. It was decided that Molly would join the Adventures on Rails cast. This was made official by presenting her full backstory in Real Engines. In 2018, Emily also joined the cast after her status was disputed in the past two years. As of Work and Play, she is part of the cast. In addition, both engines were written into the revision of James and Percy further establishing them as part of the official cast. It has also been announced that Thomas and the Avalanche will be revised in December 2019 with Connor and Caitlin being replaced by Pip and Emma and Flying Scotsman.


  • Paxton and Norman were meant to be introduced in this series, but instead joined the Adventures on Rails cast by being introduced in the thirteenth season.
  • This series was also meant to given the main cast of Adventures on Rails (excluding Thomas, David, Dodger, Delete, and Russell as they had already been properly introduced) their own proper backstories most of them lack. This was cancelled due to lack of interest, and it was then decided that only characters not introduced should receive their proper backstory.
  • This will be the last Adventures on Rails related project.
  • The series was originally was going to be 20 episodes long, but then was extended to 26 episodes to given proper introductions to more recent characters of the Television Series. It was also due to air from July 1st to August 1st, 2015, but was rescheduled to July 1st to July 30th, 2015.
  • This mini-series will lead right into the upcoming short, The End of the North Western Railway in November 2015.
  • All episodes have forewords much like season post-Season 12 in Adventures on Rails.
