50 free Infinity Train trivia questions with answers — trivia quiz, new questions added Oct 2026.
Infinity Train packs a lot of story into a short episode list: four books of ten episodes each, most of them named for the car they visit. Each book follows different passengers through a seemingly endless train whose cars hold whole worlds, from a kingdom of talking corgis to a carnival run by a cat. This quiz walks the episode list book by book. It asks which episodes open and close each story, what happens in the most memorable cars, and who the passengers and denizens are, from Tulip and One-One to MT, Jesse, Grace, Simon, Ryan and Min-Gi. A few questions cover the voice cast and how the series was made and released. It is written for fans who have ridden the whole train and want to see how much of the episode guide stuck. Every answer comes with a short explanation, so a miss still tells you something about the show.
