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.

One-One's negative persona (Sad One) is voiced by series creator Owen Dennis.

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.

Each season of Infinity Train is narratively similar to a famous children's story.

• Book One takes inspiration from Alice's Adventures in Wonderland by Lewis Carroll.
• Book Two is basically Carlo Collodi's The Adventures of Pinocchio.
• Book Three has references to J. M. Barrie's Peter Pan.
• Book Four's protagonists resemble Mark Twain's The Prince and The Pauper.

Also, if the show were to continue and not get canceled. The other planed and canceled seasons' narratively to famous stories such as:

• Book Five would have references to The Snow Queen by Hans Christian Andersen
• Book Six would be basically The Phantom Tollbooth by Norton Juster
• Book Seven would take inspirations from the first three Oz books (The Wonderful Wizard of Oz, The Marvelous Land of Oz and Ozma of Oz) by L. Frank Baum that would make it the longest season of the series.
• Book Eight and the final season would not take inspiration or have references to a real famous children's story but would be based on an unpublished book by the show's creator Owen Dennis' grandfather about his experience with and going through Alzheimer's disease.
