# Thomas & Friends: All Engines Go

Thomas & Friends: All Engines Go is an American animated comedy children's television series created by Britt Allcroft and developed by Rick Suvalle that premiered on Cartoon Network's Cartoonito block in the United States on September 13, 2021, and on Treehouse in Canada on September 18, 2021. It is produced by Mattel Television and animated by Nelvana.
The series serves as 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 two seasons labeled as series 25 and 26), 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.

## Plot

The series focuses on the adventures of a younger version of Thomas the Tank Engine and his friends, including Percy, Nia, Kana, and Diesel. Throughout the episodes, they learn many life lessons and solve problems, while going around on their daily lives doing jobs, with help from each other and the other residents and visitors of the Island of Sodor.

## Production

In October 2020, Mattel Television formed a new co-production partnership with Corus Entertainment's Nelvana Studio and greenlit two new seasons for the Thomas & Friends series, consisting of 104 11-minute episodes and two hour-long specials. The new episodes were said to be produced using 2D animation and include more physical comedy and music than before.
The new series was officially announced on February 5, 2021. Executive producer Christopher Keenan said it was, "crafted to appeal to contemporary audiences' sensibilities while maintaining Thomas' core brand ethos".
On October 11, 2022, Mattel announced that the series was renewed for a third and fourth season, each consisting of 26 episodes and a special. On February 27, 2024, it was announced that Series 3 would debut on Netflix in the United States.
Unlike previous Thomas the Tank Engine media, All Engines Go was produced in North America rather than the United Kingdom.

## Reception

The premiere of the show, along with trailers and other promotional material were met with immense criticism from fans and parents of the original show, largely towards the new redesigns of the characters. Joly Herman at Common Sense Media summed up her review of the series by saying, "As cute, fun, adventurous as this series might be to young viewers, it has lost some of the character that the original show enjoyed."
Britt Allcroft, who produced the first seven series of Thomas, expressed disdain with All Engines Go, stating the series lacked the "magic" of the original series.
The series won Best Preschool Series in the inaugural Collision Awards in 2024.
