This article lists and details episodes from the 24th and last or final series of the show, which premiered on 2 May 2020 in the United Kingdom, and 1 September 2020 in the United States on Netflix.[1]
The series consists of 20 regular episodes as well as three half-hour specials: "A New Arrival", "World of Tomorrow", and "Thomas and the Royal Engine". The first two form a movie entitled "Marvelous Machinery”, while the latter is a celebratory episode commemorating the 75th anniversary of the original books.
As the "Big World! Big Adventures!" rebrand of the show was deemed a failure, Series 24 became the last series of the original Thomas & Friends series, with the next series retooled into Thomas & Friends: All Engines Go, a complete reboot of the series.

The next day, Thomas is ready to watch Ace do his jump, but he realizes that Ace can't find the double decker buses everywhere, likely because none of the double decker buses have shown up. Thomas, Shane, Tamika, Aubrey and Aidan (The Kings of the Railway) decide to position themselves on the track so that Ace can jump over them, and the Super Stunt Rally is a success.
When Thomas finds out that the Earl's Technology Fair will bring new inventions to Sodor, he sets out to prove that steam engines are the best inventions ever, as Ruth, an American inventor who wanted to be a railway engineer, tells Thomas that he and the other steam engines are one of the best. Meanwhile, an engine from the Mainland named Sonny arrives on Sodor bringing two men named Baz and Bernie who are plotting to steal one of the inventions to get rich.
After meeting Kenji, a fast electric diesel engine, the steam team become worried that they will be replaced by new inventions. As the Technology Fair commences, Baz and Bernie try to find the best invention to steal, until they settle on stealing the blueprints for Ruth's hover car. However, Sonny stands up to the pair, encouraged by the idea of becoming a really useful engine after meeting Thomas, who teaches him the ways of the Fat Controller's railway. As a result, Baz and Bernie use Kenji as their getaway vehicle instead and tie Sonny's regulator open to create a distraction. After being caught by Thomas, Sonny reveals Baz and Bernie's intentions. Once Thomas catches up to Kenji with a jet engine, Baz and Bernie are taken away by the policemen.

Sonny reverses to the siding, derailing the fish trucks over the points in the process, and saves Diesel.
