Infinity Train is an American animated series created by Owen Dennis that first aired in August 5th, 2019. Majority of the show takes place on a seemingly never-ending train, colloquially named the "Infinity Train". Each train car contains its own expansive environment with various denizens that will either befriend or try to harm the passengers that pass through their doors.

People who end up on the train are picked up to deal with their trauma and emotional issues. Their progress is tracked by a number printed onto the palm of their hand. Each passenger gets a different number that corresponds with the problems they need to grapple with. Negative progress results in one's number going up, while positive progress causes the number to go down until they get to 0 and they can leave the train.

Show Runtime (2019-2021)

As of 2023, there are four seasons, each with 10 episodes. Book 1 aired in August of 2019 on Cartoon Network, Book 2 aired on January of 2020 on Cartoon Network, Book 3 aired on August of 2020 on HBOmax, and Book 4 aired on April of 2021 on HBOmax. The series was intended to have 8 seasons, also called "books" but the show was unfourtunately cancelled in 2021. To this day, the creator and fans alike cling onto the hope of the show getting picked up again.

(Mostly) Spoiler Free Synopsis

Tulip, Atticus, and One-One all together.

She surprisingly comes across a train claiming to take her specifically to her coding camp.Little did she know that she would instead be taken into a whole new world: a train that goes on forever! She has to find a way to get back home, but it seems that something is trying to get in the way of that.

Book 2 is about a chrome reflection named "MT" trying to find a way off the train after escaping the mirror realm. Together, with a 14 year old boy named Jesse Cosay, they search for an exit while evading the cops trying to apprehend MT.

Book 3 is the story of two teenagers named Grace Monroe and Simon Laurent. The two co-lead the Apex, a group of kids who ransack train cars and terrorize the denizens in them. Their ideology is centered around "the true conductor" of the train, who they believe has the highest number on the train. Ergo, they strive to keep their numbers high. A surprising turn of events leads Grace and Simon to become separated from the rest of the Apex. They spend the season trying to get back to the Apex.

Ryan and Min-Gi have aspired to be musicians all their lives, but when their partnership crumbles, they drift away from each other. However, that all changes when Ryan returns to try and bring the band back together. This fails, resulting in a chase that lands them on a train. The two enter the infinity train together, a first for the train's known history. Now, they will need to work out their problems together, or die trying.

A mockup of the would-be movie of Book 5, created by Owen Dennis.

Over time, Owen Dennis revealed some ofthe various ideas he had planned for the rest of the Infinity Train series. The biggest one would be Book 5, the season that ran concurrent to Book 4. This season would have centered Amelia Hughes and her rise to power as the conductor of the train. It would've been a movie. Because Infinity Train was cancelled at Book 4, the only thing to show for it is a completed script, a mockup created by Dennis himself, and some blurry storyboards.

A Christmas special was also planned, featuring most of the main cast (except for Simon, who is dead [this is the creators words, not mine.]) all together. Not much is said about it.

Owen Dennis at some point posted a photo of a potential passenger named Blake. Blake would have presumably been the protagonist of Book 6, a season surrounding the theme of guilt that took place in the early 2000s.

Other projects involved the following:

  • A VR game that took place in Corginia in which the player would solve puzzles
  • A choose your own adventure novel that somewhat deviates from canon
  • Various Infinity Train comics
  • My Thoughts

    Sooooo, I heard about Infinity Train when it first aired and watched the first season on Cartoon Network. I didn't have cable for a while so I never knew that they made more seasons until Book 4 aired and it was all over my timeline. (ok, to be honest, I had seen bits and pieces of discussions about book 2 and 3... along with some of the discourse of the latter season, but I never got around to watching it because I didn't have a TV and I don't use streaming services.)

    Anyways! I was in my freshman year of college when Book 4 aired, around the same age of the protagonists of that season too! I decided to bingewatch the entire series from Book 1 to Book 4 in one sitting, and my life changed forever after that. I was OBSESSED (I still am, just to a lesser degree). I wanted all my friends and mutuals to watch the series and maybe help it get un-cancelled. You could also argue that my infinity train SpIn (special interest) influenced my developing artstyle with the way I drew fanart of that show. I still do to this day. It's kind of hard for me to draw literally anything else. And so this show has been my personality for 2 years and counting. I love LOVE this show with all my heart and I hope one day the execs wisen up and let the show have its full intended run and then some.
