Season 4

The **fourth season** of The Adventures of Thomas first released on October 4th, 2021. It ran for sixteen episodes until January 20th, 2023.

## Production/History

After the production of Season 3, the creator's brother moves back into the new house. This meant that there is less room to be filmed. Production started in July 2021 with the first two episodes (the former planned to be made during the first season) filmed in the creator's room. The production of the fourth season is to be split into 3 segments: Season 4A was made in 2021, Season 4B being made in 2022, and Season 4C being made in Late-2022. It uses uberduck.ai for the narration with some exceptions.

In September 2022, the creator announces that the season will be reduced from eighteen to sixteen episodes due to him getting a job and college.

In December 2022, the season concluded production.
