Series 23 of Thomas & Friends began airing on 18 May 2019 in the US and 2 September 2019 in the UK.


Mattel green-lit a new series and several specials for Thomas & Friends that premiered in 2019. Production began on the twenty-third series which consisted of 20 x 11-minute episodes as well as three 22-minute specials following the recent revamp of the series.

The series is once again, split into two halves: one half with Thomas travelling around the world, and one half taking place on the Island of Sodor. Along with more episodes set in the previously visited China, India and Australia, Thomas will also visit two new countries, Italy and Brazil.

Mattel later ended the new deal with Nickelodeon for the show's airing rights, and the series was then streamed on Netflix for the franchise's future.
