The fourth series of Thomas & Friends: All Engines Go was greenlit by Mattel in August 2022[2] and premiered on Channel 5's Milkshake! block in the United Kingdom on 27 January 2025. It will also premiere Netflix in the United States and on Treehouse TV in Canada later in the year.

This series was produced in honour of the 80th anniversary of The Railway Series.

Production

Due to the massive success of the Thomas & Friends: All Engines Go reboot, Mattel announced during their 2022 press conference that the show had officially been renewed for two additional series and would carry the franchise through 2025.[2]

Unlike the previous two series, Series 3 and 4 only feature 26 11-minute episodes as opposed to 52, much like many series of the original television series.

Description

Thomas, Percy, Diesel, Kana, Nia, Bruno, and the rest of the Sodor loc-amigos are back on track for a new season of delights, delays, and the occasional duckling dilemma as they travel the Island of Sodor. These fast friends show they are up to the task for the weird work they love, supporting each other through the stinkiest muck, up the steepest hill, and when they've made mistakes. The vehicles roll up to new challenges including a multi-episode construction project, more than a few McColl mix-ups, and a dazzlingly daring delivery by Bruno. No rail is too rocky and no job is too impossible for the Number One Engine and team, especially when they work - and sing - together![3]
