Thomas & Friends: All Engines Go (2021–2025) watch online

Thomas & Friends: All Engines Go is an animated children's television series created by Britt Allcroft and developed by Rick Suvalle that originally aired on Cartoon Network's Cartoonito block in the United States from September 13, 2021, to November 27, 2023, and premiered on Treehouse in Canada on September 18, 2021. The series was later released on Netflix in the United States from March 7, 2024, to September 11, 2025. It was produced by Mattel Television and animated by Corus Entertainment's Nelvana.

The series is a reboot of the original Thomas & Friends series that ran from 1984 until 2021. It was originally believed to be a continuation of the original series (with the four seasons labeled as series 25–28), but Mattel Television later confirmed it to be a separate series. It introduces "an entirely new approach to Thomas & Friends content", with a new animation style and story structure.

In October 2022, the series was renewed for two more seasons of 26 episodes each. The final episodes were released on September 11, 2025. Following the show's conclusion, Mattel later announced a new television series for the franchise in May 2025, with a sneak preview releasing in January 2026. This new series aims to be more faithful to the style and feel of the original series.
