  • This season marks the first of a few things:
    • The first season where Hiro, Stanley, Captain, and Harold appear but do not speak.
    • The first season not to have Togo Igawa as part of the voice cast.
    • Skarloey, Rheneas, Sir Handel, Peter Sam and Rusty's first appearances in full CGI.
    • The Skarloey Railway Depot, The Lighthouse and the Sodor Suspension Bridge's first appearances in full CGI.
    • The first season since the thirteenth season where the trucks have faces.
    • The first season to feature Matt Wilkinson as Butch in the UK version.
    • The first season to feature Ian McCue as producer.
    • The first and only season to feature Rebecca Evans as script editor.
    • The first and only season for which all of the episodes (except The Christmas Tree Express) aired in Australia before airing in other countries. However, selected episodes from the seventeenth and eighteenth seasons also aired in Australia ahead of their overseas debuts.
    • The first season where the end credits only list the cast members who provide voices in the particular episodes. The only exceptions are the UK dub of Whiff's Wish, where Ben Small is incorrectly added to the list of voice actors despite none of his characters speaking in that dub, and the UK dub of Don't Bother Victor, where Steven Kynman is not credited despite voicing Peter Sam.
  • This season marks the last of a couple of things:
    • Sharon Miller's last season as head writer.
    • Greg Tiernan's last season as director.
    • Nicole Stinn's last season as producer.
    • The last season to feature Matt Wilkinson as Victor in the UK. David Bedella takes over the role in Blue Mountain Mystery.
    • Sam Barlow's last season as story executive.
    • The last season animated by Nitrogen Studios.
    • The last season to feature Bash and Dash.
    • The last season to feature Misty Island. It was later mentioned in the twentieth season episode, The Way She Does It.
    • The last season to feature Glenn Wrage as Butch in the US. Steven Kynman took over the role in the seventeenth season.
    • The last season which Emily shares Henry's whistle sound.
    • The last season to feature Teresa Gallagher and Jules de Jongh as Rosie in the UK and US, respectively. Nicola Stapleton later took over the role in Journey Beyond Sodor.
    • The last season in fullscreen in Italy, Brazil, Mexico, Canada, Latin America, the UK (Nick Jr. broadcasts only) and in the US (but in some PBS broadcasts).
    • The last season narrated by Michael Brandon and Michael Angelis for the US and UK, respectively, and the last to have two separate narrators for the UK and US until Big World! Big Adventures! and the twenty-second season.
    • The last season to have twenty episodes.
    • The last season to have Rupert Degas as part of the voice cast. Keith Wickham took over the role of Bertie and Steven Kynman took over the role of Dart. Ben Small only voiced Flynn in the seventeenth season, then this role was given to Glenn Wrage and later, Rob Rackstraw in the nineteenth season.
    • The last season to have a character voiced by the narrator in the US version (Diesel in this case as Martin Sherman took over the role of this character until the eighteenth season and Mark Moraghan was the narrator from the seventeenth season to Big World! Big Adventures! The Movie and the twenty-first season).
    • The last season where Ben Small voices Ferdinand in the UK dub.
    • The last season to have the steam engines' whistles budge up and down when they use them.
  • Skarloey, Rheneas and Peter Sam's whistles now budge up and down when they use them.
  • Prior to the narrow gauge engines' return, the team went to the Talyllyn Railway to measure the real engines to make the Skarloey engines. Unfortunately, Douglas (Duncan's basis) was under an overhaul and thus could not be measured. This could be why Duncan does not appear in this season, Blue Mountain Mystery, King of the Railway and Season 17.
  • On Netflix UK, this series was incorrectly listed as Season 14. The mistake was later corrected.
  • In Norway, this season was shown on the TV 2 Sumo website before airing on television.
