Infinity Train is an American animated drama anthology television series created by Owen Dennis, previously a writer and storyboard artist on Regular Show, for Cartoon Network. The pilot was first released on the Cartoon Network App and VOD on November 1, 2016, and released the following day on the official Cartoon Network YouTube channel. Cartoon Network greenlit a full series due to positive reception; the series premiered on August 5, 2019. Three seasons have been released: the first two on Cartoon Network, and the third on HBO Max.
The series is set on a gigantic, mysterious and seemingly endless train traveling through a barren landscape, whose cars contain a variety of bizarre, fantastical and impossible environments; each season (referred to as a "Book") follows a different set of characters, as they explore the train. The first season, retroactively titled The Perennial Child, follows a girl named Tulip trying to escape with the help of a robot named One-One and the talking dog Atticus, while the second, Cracked Reflection, focuses on "MT", Tulip's reflection from the mirror world, who befriends a boy named Jesse and a deer they name Alan Dracula. The third season, Cult of the Conductor, follows Grace and Simon, leaders of the Apex, a gang of rogue passengers introduced in the second season, as they meet a young girl named Hazel, who is traveling with a gorilla named Tuba.
Upon its debut, Infinity Train received critical acclaim for its plot, characters, visual animation style and voice acting. It was initially promoted as a miniseries, but following the first season's finale it was announced that Infinity Train would continue as an anthology series instead. The second season debuted on Cartoon Network on January 6, 2020; the third season began airing on HBO Max on August 13, 2020, with ten episodes airing across three weeks.
The series is set on a seemingly endless train traveling through a barren landscape; the cars of the train contain a variety of bizarre and fantastical environments. The passengers on the train are people it picks up who have unresolved emotional issues or trauma. As they travel through the train's cars, passengers' adventures give them the opportunity to confront and resolve their emotional problems, represented by a glowing number on their hand that goes down as they confront these issues. Once they resolve their issues and their number reaches zero, a portal opens and they are able to leave the train and return home.
The first season focuses on Tulip Olsen, a girl struggling with her parents' recent divorce. She is accompanied by a small, confused robot named "One-One", and Atticus, the ruler of a kingdom of talking corgis. She eventually uncovers many of the train's secrets and confronts Amelia, a passenger who, instead of resolving her trauma from her husband's death, has usurped the role of Conductor from One-One and tried to take control of the train. Before leaving the train, Tulip persuades Amelia to try to adapt to the changes in her life.
In one first-season episode, Tulip frees her own reflection from the mirror world, and the two part ways. The second season focuses on the emancipated Mirror Tulip ("MT"), now on the run from enforcers attempting to kill her as punishment for abandoning her role as Tulip's reflection. She teams up with Jesse, a new train passenger, as well as Alan Dracula, a silent deer with a variety of powers. She helps Jesse leave the train by learning to stand up for himself, and he returns to the train to help her escape to the outside world as well.
The third season centers on Grace and Simon, the leaders of a gang of rogue passengers who vandalize the train and attack its denizens to keep their numbers high. Traveling with a young girl named Hazel and her gorilla friend Tuba makes Grace more sympathetic to the train's denizens. After Simon kills Tuba, it is revealed that Hazel herself is one of Amelia's creations, and Grace realizes what she thought she knew about the train is wrong. In the end, after fighting off Simon's attempt to usurp control, Grace tries to face up to and mend her mistakes.

She is analytical, down-to-earth, and determined to get off the train.
- One-One – A spherical robot consisting of two separate hemisphere-shaped robots. In Book 1, One-One accompanies Tulip on her journey, and eventually learns that it is the rightful Conductor of the train.

At the start of Book 2, she has been living on the train as a fugitive from the reflection police.

Upon escaping from the train at the end of Book 2, she names herself Lake.
- Jesse Cosay (voiced by Robbie Daymond) – A passenger who becomes MT's friend and helps her escape the train. He is easygoing and friendly, but has a hard time standing up for himself and resisting bullies; his experience on the train teaches him how to stand up for his friends.

Book 3 – Cult of the Conductor
- Grace Monroe (voiced by Kirby Howell-Baptiste; voiced by Brooke Singleton as a child) – The young adult leader of the Apex, a gang of passengers who, due to inadvertent actions by Amelia, aim to raise their numbers to remain on the train indefinitely. After being an antagonist in Book 2, in Book 3 she gradually begins to see the error of her ways and decides to try to fix her mistakes.
- Simon Laurent (voiced by Kyle McCarley) - Grace's second-in-command. His unwillingness to acknowledge and learn from his mistakes turns him into the main antagonist of Book 3.
- Hazel (voiced by Isabella Abiera) - A 6-year-old girl who travels the train. Although she has a number on her hand, it does not glow; the characters eventually learn that she is actually a denizen of the train created by Amelia's experiments.

- The Cat (voiced by Kate Mulgrew) – A talking cat who is a collector and con artist. In Book 1, she is an agent for Amelia; in Book 2, she runs a carnival.

- Randall (voiced by Rhys Darby) - A sentient liquid person who tries to build a business involving the distribution of the "Donut Holer" (which is just an ordinary pipe used to poke a hole through various objects) with his duplicates, that of which he creates at will, as proposed by The Cat. He helps Tulip steal One-One back from The Cat in "The Beach Car". (Recurring Book 1; Guest Book 2 and Book 3)

Conception and influences
Owen Dennis conceived Infinity Train in 2010, originally as a film. He was inspired by "the feeling of waking up in an unsettling space" which he felt while on a return flight to the U.S. from China. Claiming when he had "woken up. I looked around, and there were a bunch of people staring into screens in the dark in this quiet room. I thought this was kind of creepy. And it sort of started from there." Like protagonist Tulip, Dennis created video games as an amateur in his teens, including point-and-click adventure games and mods for titles such as Half-Life 2 and Unreal Tournament 2004. He has stated that Myst has been one of his primary influences since he was 13, and its influence continued in Infinity Train. He also cites Doctor Who, Agatha Christie, The NeverEnding Story, The Matrix, Philip K. Dick, Star Trek: Voyager and Sliders as influences, along with novels such as Nightbirds on Nantucket and The Wolves of Willoughby Chase. Dennis has also 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.
The pilot was first released on the Cartoon Network App and VOD on November 1, 2016, and released the following day on the official Cartoon Network YouTube channel. The short garnered a million views within its first month of availability and has since gained 5.2 million views as of July 2020, making it the most viewed pilot on the channel while two other originals, Welcome to My Life is the second most viewed pilot, and Twelve Forever (later moved to Netflix) being the third most viewed pilot. A petition to greenlight Infinity Train was made shortly after the pilot was released and garnered over 57,000 signatures. On March 11, 2018, Cartoon Network's official website launched a teaser for Infinity Train that confirmed the pilot had been greenlit as a full series and would premiere in 2019.
In July 2018, a sneak peek of the first season was revealed on the Cartoon Network panel at the 2018 San Diego Comic-Con. It was released a couple of hours later on Cartoon Network's social media platforms. A full trailer for Infinity Train was released in June 2019 which was unlocked by playing the show theme on the Infinity Train website. It was later uploaded to Cartoon Network's YouTube channel. On July 11, 2019, the show was confirmed to premiere on August 5, 2019. On July 20, 2019, the first episode was shown during the Infinity Train panel at San Diego Comic-Con. It was then released on the Cartoon Network app and website later that same day. The first season would be 10 episodes long, with two episodes airing each night from August 5 to August 9, 2019.
From October 18, 2019, Cartoon Network started uploading a series of Infinity Train shorts onto their app and YouTube channel called "The Train Documentaries", which focused on One-One showing off a number of cars in the train, including "The Green Car", "Tiny Wizard Car", "The Kaiju Car" and "The Tech Support Car".
A promo after the final episode of the first season confirmed the series would return. On November 22, 2019, the Infinity Train website was updated with a new claw machine puzzle. Completing the puzzle leads to a trailer for Book 2. The trailer was then released officially the next day. Book Two debuted on January 6, 2020.
On July 6, 2020, Book 3 was officially announced with a release date of August 13, 2020.  Unlike its predecessors, it aired on HBO Max instead of Cartoon Network. Dennis revealed in a reply to a tweet that Infinity Train was originally planned to air on HBO Max from the beginning, but due to the streaming service's delay from its original 2019 launch date, the first two seasons were aired on Cartoon Network instead. It was later revealed at San Diego Comic-Con that the book would be titled Cult of the Conductor. Book 3 was released in batches, with the first five episodes debuting on August 13, the next three on August 20, and the final two on August 27.
Inifinity Train was created by Owen Dennis previously a storyboard artist for Regular Show and Ben 10: Ultimate Alien and later director on the 2012 Ben 10: Omniverse sequel. The series has five writers in addition to showrunner Dennis and executive producer Keith Mack. They worked in two teams, each comprising a director and three board artists. The animation is made by Studio Mir in South Korea using traditional animation methods. About sixty people worked on the series at Cartoon Network and about fifty-five at Studio Mir.
Owen Dennis claims the show is at risk of not being renewed for a fourth season, in part because of "trepidation over the subject matter"—i.e., a concern on the part of Cartoon Network and HBO Max decision-makers that the show's content is too mature for children.
On August 16, 2020, Dennis reported that though the team wanted to make more episodes, production had ended for the time being with the whole crew laid off and everyone getting new jobs. Dennis noted further episodes depended on the viewership numbers on HBO Max.
Dennis said he has several more seasons planned should the series continue. When asked what stories Dennis would like to explore in the future, he said he wants to go more into the history of the train—possibly to a time when the Infinity Train existed before trains themselves. Dennis also said "We have rough ideas for themes and which characters we'd like to follow for five more seasons, up to season eight. Feels like '8' is a good place to stop because it looks like an infinity symbol."
When asked what else he would like to do with Infinity Train in the future, Dennis said "I'd love for there to be a movie that follows Amelia's story [the villain from season one]. I'd also like to do some other time periods of the train." Dennis also expressed interest in doing some Infinity Train comic books that "are in canon and could be written by or starring non-Americans."

Infinity Train received critical acclaim upon its debut. It currently sits at 100% on Rotten Tomatoes. Caroline Cao of /Film declared it a "wild triumph", while Nerdist's Andrea Towers declared it "one of the best animated programs of the year." Reuben Baron of CBR compared it to Cartoon Network's animated miniseries Over the Garden Wall in its perfection, hailing it as "a beautifully handled piece of self-contained, character-driven storytelling." Skyler Johnson from Comic Watch called it "excellent", with "emotional depth that is rarely seen in children's television", "witty, clever humor", and "stellar voice action." Emily Ashby of Common Sense Media gave the series 5 out of 5 stars. In her review Ashby praised the positive messages about friendship and self-reflection. Ashby also praised the character of Tulip and the show’s emotional moments.
The third season of Infinity Train also received critical acclaim. William Hughes of The A.V. Club praised season 3 for its darker themes and messages, hailing it as "the best, most challenging season yet." Petrana Radulovic from Polygon praised the series' complex character arcs and noted the third season is a testament to the infinite potential of the premise. Andrew Kolondra Jr. from The Vanderbilt Hustler called season 3 "genre-defying" and said "thanks to shows like Infinity Train, the modern animation world is finally approaching a point at which it may break free of the notion that animation is ‘just for kids.’" Observer Media said the show has grown into its own, developing a compelling world and internal mysteries "that will draw you in with a masterclass in character development to fuel your drive to keep going."
To test the waters for a potential full series, the pilot for Infinity Train was first aired on Cartoon Network on Saturday February 11, 2017 at 6:00 AM without any advertisements for it. Despite this, the pilot pulled in approximately 703,000 views amongst the 18–49 year old demographic and ranked as the 33rd of the top 50 original cable telecasts for February 11, 2017.
In September 2020, Parrot Analytics found that the audience demand for Infinity Train was 21.3 times the demand of the average TV series in the United States within 30 days of its release.
