Season 1

Season 1 of Ready Steady Engine! will begin airing in January-June 2020.

Production
Series ?? alongside Ready Steady Engine! (not counting Big World! Big Adventures!) marks the major reboot of the franchise. Both productions were the result of the market research Mattel conducted with audiences around the globe. It was about how Mattel could keep Thomas & Friends relevant in a competitive market, as well as reversing declining toy sales. The one suggestion Mattel was intrigued with came from a child declaring "Thomas is a train but he never really goes anywhere". This evolved into Thomas travelling around the globe and learning about different cultures.

The episodes retained their eleven minute-long runtime but were now broken into seven-minute-long stories, with an additional four minutes reserved for a variety of segments like sing-along karaoke songs, music videos or segments of Thomas talking directly with the audience about lessons learned during a particular episode. Additionally, all episodes have a fantasy sequence and six of the seventeen development goals Mattel chose from the United Nations are featured. Among many other changes, Edward, Henry and Duck were removed from the Steam Team to make room for Emily (even though she was a main character in Series 13-21 while Duck was absent in Series 13-16, then returned in Series 17 and has appeared ever since), Nia and Rebecca in order to move the gender ratio among the main cast to a 50/50 split between male and female characters, with an episode focused on addressing their removal. Toby was also quietly dropped from the Steam Team for the same reason, and the narrator was replaced with Thomas in a first-person perspective. Despite this, Mark Moraghan has said that he will still work on the series. In the twenty-second series episode, School of Duck, he voiced an old coach named Dexter who was converted into a school classroom. He also now portrays a character in live-action segments named Mr. Evans, replacing the late Ben Forster's role as Mr. Perkins a year after Forster died on 2nd January 2017 after following a battle with cancer.

Season 1 of Ready Steady Engine! is set after the Spin-Off Series, Big World! Big Adventures! The series is split into two halves: one half with Thomas travelling around the world, visiting China, India and Australia and one half taking place on the Island of Sodor.
