  • Nitrogen Studios began production on this series in November 2009.[1]
  • This series was supposed to be shown after Day of the Diesels, but was brought forwards for unknown reasons.

    • Butch's first speaking role in the television series.
    • Trevor's first episodic appearance in full CGI.
    • Arlesdale End, Castle Loch, the Norramby Fishing Village and Wellsworth's first appearances in full CGI.

    • The first series to have an episode written by Gerard Foster.
    • The first series, with Series 20 being the second, not to have Thomas' name titled in any of the episodes.
    • This is also the only series of two things:
      • The only series to date, where Thomas, Gordon and Percy have more roles than the rest of the Steam Team.
      • The only series to date where Annie and Clarabel are never referred to by name.
      • The only series to have episodes written by Laurie Israel, Rachel Ruderman, Neil Ben, and Lizzie Ennever.

    • The last series dubbed in Finnish until the twenty-second series.
    • Also The last series narrated by Aku Laitinen in Finland.
  • This is the second series of one thing:
    • The second series since Series 8 not to introduce any new engines.
  • Percy's whistle now budges up and down whenever he uses it.
  • Jules de Jongh is credited in the UK credits despite none of her characters speaking in that dub.
  • On Netflix UK, this series was listed as being Series 13. The mistake was later corrected.
  • In Finland, this series was shown on the website MTV Juniori before airing on television.
  • This is the second series after Series 12 when James is least prominent, once again speaking in only two episodes.
