While most of the episodes are original stories, some of them are adapted from the original show's first five seasons with changes in addition to other kinds of unadapted The Railway Series stories with interesting concepts.
- Unlike the theatrical film in which is a live-action/CGI hybrid, the television series is fully computer-animated, while using models, elements, environments and such Pixar originally created for that.
- In addition to remaking the plots from previous Thomas storylines, the series also adapts newer, yet interesting storylines that aren't adapted as well (albeit with changes to reflect with the 1940s-50s time period of the series).
- During the series' development, following the movie/film's big success in box office and critical reception, Disney acquired the franchise's distribution and production rights from Mattel, having also bought HiT Entertainment (listing them as special thanks and keeping their logo on Disney+ airings, replacing Mattel's in Season 21 and the film), while Richard Awdry, Christopher's son, continues The Railway Series with "The Little Blue Engines" (which tells the story of Edward and Thomas' adventures when they first arrived on the North Western Railway) and an adaptation of the film itself.
