Trivia

 * The twenty-fourth series of Thomas & Friends aired along with the first season of All Engines Go on the channel. The first season of All Engines Go would air around 9:50am, while the twenty-fourth series of Thomas & Friends would air around 15:40pm.
 * Starting with Counting Cows, the episode code and an image of Gordon Gets the Giggles were used for the episodes. However, on 23rd July 2022, Counting Cows, Music Is Everywhere, Backwards Day and Chasing Rainbows were corrected. At some point between the 26th and 28th July 2022, the images for Nia's Balloon Blunder, Capture The Flag, Mystery Boxcars, Super Screen Cleaners, Overnight Stop and The Joke Is On Thomas were corrected. This error partially happened again with the episode Whistle Woes, with "2518b" beside it before being corrected 22th August 2022. However, the full error would happen again with An UnbeLEAFable Day. But these errors expect for An UnbeLEAFable Day were corrected on 1st September 2022.
 * For the first few All Engines Go episode images up until Counting Cows (with the exception of Kana Goes Slow), on the RTÉ Player, the images that are used were from the All Engines Go Wiki. However, when the images and titles were corrected for Counting Cows, Music is Everywhere, Backwards Day and Chasing Rainbows on 23rd July 2022, they would use images from the Thomas the Tank Engine Wikia.
