Corginia is for Corgi Lovers[]
Released: March 11, 2018
Infinity Train - Corginia is For Corgi Lovers Travel Commercial - Cartoon Network
The first teaser trailer for the full series. Ostensibly a travel agency advertisement encouraging viewers to visit Corginia, with the narrator referencing moments from the pilot including the "shadow monster" and the catchphrase "We get very excited when someone new comes through the door." The ad is soon interrupted before cutting to an image of a green light forming an infinity symbol, within which the number "2019" appears, accompanied by the Infinity Train theme. This trailer, along with an accompanying Cartoon Network teaser site, marked the public reveal that Infinity Train had been greenlit for a full series.[1][2]
2018 San Diego Comic-Con Official Clip[]
Released: July 22, 2018
Infinity Train Official Clip (Reupload)
First shown at the Cartoon Network panel at San Diego Comic-Con 2018. Over shots of an empty bedroom, we hear Megan Olsen calling for Tulip to come downstairs, only to get no reply. The scene transitions to a shot of a terrified Tulip standing in the Wasteland, before looking at her palm and opening her fingers to reveal a rapidly changing number, which settles at 115. The Infinity Train Cartoon Network logo appears, accompanied by the theme. This trailer uses an original animation made by Owen Dennis, although at the time he made it he had forgotten what Tulip's head design was, resulting in her having what has been referred to as a "bucket head" shape.[3]

Official Infinity Train Trailer With Alternative Ending - Cartoon Network
The first official trailer for the series was released on Cartoon Network's dedicated Infinity Train website. It was hidden behind a game set in the Keyboard Car: playing the Infinity Train theme on the keyboard led viewers to the trailer. Cartoon Network later uploaded the same trailer to their YouTube channel, with an alternate ending featuring Mildred the Tyrannosaur.

Infinity Train - Official Trailer - SDCC 2019
This trailer debuted at the Infinity Train panel at San Diego Comic-Con 2019. It utilizes footage from the first five episodes of Book One. Notable for using "Crazy Train" by Ozzy Osbourne, and confirming the series premiere of August 5, 2019. Note that it refers to the series as a "five-night special event": it was widely believed at the time that Infinity Train was to be a miniseries à la Over the Garden Wall.
Destination Unknown[]
- Main article: Destination Unknown
Released: July 20, 2019
A unique animation created to promote the six-hour countdown livestream on Cartoon Network's Official YouTube Channel, featuring One-One, surprising viewers by revealing they were about to watch the first episode. Later re-released for San Diego Comic-Con 2019, when attendees were also given the chance to watch the first episode.
Until Next Time[]
Released: August 9, 2019
Until Next Time - Infinity Train - Cartoon Network
Every episode of Infinity Train during its initial five-night airing on Cartoon Network ended with a shot of the lights on the train rapidly passing by, followed by a teaser for the following night's episodes. On the final night, however, after the airing of "The Engine", the passing cars were abruptly interrupted by One-One announcing to the audience he was "back as Conductor and better than ever!" (utilizing audio from the then-unreleased short "The Movie Theater Car" and footage from Destination Unknown) and then declaring that he will see them next time, followed by a message announcing that "Infinity Train will return." This was the first official confirmation that Infinity Train would have more episodes beyond the initial first season.
Book Two - Cracked Reflection[]
Book Two Trailer[]
Released: November 23, 2019
Infinity Train Book Two Official Trailer Cartoon Network
Similar to Book One's first official trailer, Book Two's trailer was hidden behind a game on Cartoon Network's official Infinity Train website: users would have to play a crane game (from The Lucky Cat Car) where they needed to guide Alan Dracula to a flower and capture him, whereupon the trailer would play. Cartoon Network later released the video on their YouTube channel. Much like the Book One trailer's use of "Crazy Train", this trailer uses the Banshees' cover of "The Passenger" by Iggy Pop.
