This article is about the train. Did you mean the pilot, or the series itself?
The Infinity Train is the main setting of the series of the same name.
While it appears as a regular train on the outside, it is actually of infinite length. Inside of its many boxcars, practically anything conceivable can be found, whether it be puzzles, objects, or even entire worlds. According to Owen Dennis, it is around 5 stories tall.
These are the cars that are attached to the train and have been shown/mentioned in the show.
|Pilot||Five Unknown Cars||Mentioned only||After exiting the Puzzle Car, it is revealed, that One-One speculated previous eight cars to be fart cars. Three of those mentioned cars are known (The Bubble Car, Chess Car, and Puzzle Car).|
|Bubble Car||Briefly seen|
|Chess Car||Briefly seen|
|Puzzle Car||Story setting|
|Unknown||Cross-eyed Ducks Car||Yet to appear||Confirmed in a Cartoon Network video.|
|Gnome-Wizards Car||Yet to appear||Confirmed in a Cartoon Network video.|
|Pinball Car||Yet to appear||Confirmed in a Cartoon Network video.|
These are the cars that were not shown to be real, but instead were suggested in the show. Should the Infinity Train be truly infinite, the existence of these cars is guaranteed:
|Pilot||Burp Car||Unseen||Made up by One-One|
|Pizzeria Car||Unseen||Made up by Tulip|
- In the early art of drawing the train, each car was supposed to be stamped with the train's insignia but was removed in the Pilot. The symbol was an Ouroboros fashioned into the infinity symbol with a waning gibbous moon above it (the moon is red and the shadow on it is black; inversely, it could also be a waxing crescent).
- The infinity symbol is a mathematical symbol used to show the concept of infinity. The Ouroboros (a snake/serpent eating its own tail; usually drawn as a circle) is an ancient symbol used to depict continuity, cycles, and infinity.
- In the picture shown above, the train appears to have a valve gear, a typical gear that a steam locomotive has. But the train doesn't have a piston, so it is unknown if the train is either a Steam or a Diesel locomotive.
- In a Season 1 storyboard we see Tulip with a floating Drum and a floating saxophone behind her. It is possible this is another car.
