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.[1]


In the pilot, the train is seen traveling through an unknown desert. It is revealed that Tulip has already spent a full week on the Infinity Train, but the events leading to her boarding are unknown.

The proposed ouroboros-infinity insignia of the train.

  • 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.
