Series creator Owen Dennis has described Infinity Train as "Saw for kids," in that each season is essentially a morality play based around machinery designed to help one overcome personal issues and appreciate life.
In a Reddit AMA, Owen Dennis said that there's a whole cut scene in the season 4 episode "The Party Car" where Ryan went off to party with people, leaving Min to go and try to change under a table. Then, while he was doing that, the table turned into Alan Dracula, leaving him in his underwear in front of a bunch of people.
This series was one of many removed from HBO Max without warning after the Warner Bros. Discovery merger in 2022. Any related media was also removed from YouTube, Twitter, and music platforms. Owen Dennis criticized the removals as "unprofessional, rude, and just straight up slimy." Within days, the series topped the kids and family chart on iTunes, DVDs sold out on Walmart, Amazon, and Best Buy, and DVD prices skyrocketed on eBay. All four seasons and most of the deleted YouTube videos were also uploaded to Google Drive by fans.
