Trivia

• Many of the episodes in Series 2 have the UK name listed with the US name in brackets. One example is Thomas, Percy and the Coal, listed as "Thomas, Percy and the Coal [Double Trouble]". Several of them are also unrestored and use the UK narration. The latter applies to the following:
  • Cows
  • Old Iron
  • Percy and the Signal
  • Duck Takes Charge
  • Percy Takes the Plunge
  • Pop Goes the Diesel
  • A Close Shave
  • Better Late than Never
  • Break Van
  • Thomas Comes to Breakfast
  • Daisy
  • The Diesels
  • Woolly Bear
  • Thomas and the Missing Christmas Tree
• The thumbnail images for Diesel's Devious Deed, Time for Trouble, Granpuff and Sleeping Beauty were taken during a fade transition, meaning that two shots are overlaid on one another.
• Several third, fourth and fifth series episodes use the UK narration.
• Toad Stands By, Something In The Air (briefly), and Snow are listed twice, once with US narration and again with UK narration. Because of this, Paint Pots and Queens and Rusty and the Boulder are not included on the streaming service.
• Some Series 5 episodes are listed with alternate titles:
  • Haunted Henry is listed as "Henry and the Haunted Station", This has since been corrected.
  • Toby's Discovery is listed as "Toby Meets an Old Warrior".
  • Oliver's Find is listed as "Oliver?s Great Adventure", presumably a misspelling of "Oliver's Great Adventure". This has since been corrected.
  • Happy Ever After is listed as "Percy and the Special Present". This has since been corrected
  • Make Someone Happy is listed as "James Special Trust", presumably a misspelling of "James' Special Treat".
  • Snow is listed as "Skarloey Snowed Under" as the US dub copy.
• Series 6 episodes are all presented in 16:9 widescreen.
• A Friend in Need was once listed as "A Friend In Need (Planted Spinoff PT 2)", presumably a misspelling of "A Friend in Need (Planned Spinoff PT 2)". Oddly enough, Jack Jumps In does not have this extra notation denoting that it is the first part of the pilot.
• Edward the Very Useful Engine is listed as "Edward, the Very Useful Engine".
• Bad Day at Castle Loch is listed as "Bad Day and Castle Loch".
• The description for Snow Engine reads, "It?s time for the winter festival, but Oliver doesn?t like the snow." All of the question marks are in the place of apostrophes. This, oddly enough, only seemed to happen with episodes where Oliver has a lead role.
• The Grand Opening is listed with its UK narration and is also in widescreen.
• The trailer for the series on Roku is a clip from Thomas' Frosty Friend, an episode from the tenth series.
• Samson And The Fireworks is titled "Samson's Fear Of Fireworks"
• An Engine of Many Colours is listed as "Thomas and Friends" and had an alternate description for Apology Impossible.
• The Series 22 episodes are listed in production order.
