Infinity Train (Seasons 1–4)

Infinity Train (2019) is a Cartoon Network animated series you can watch online on iFILM — all seasons, all episodes. A girl named Tulip wakes up aboard an impossible train: car after car, each one a different world with its own rules, creatures, and puzzles. A number on her hand keeps changing. Nobody tells her what it means.

The show is structured in a way that keeps it consistently surprising: four seasons, each following a different passenger with a different emotional story to unpack. The sci-fi and fantasy settings are inventive, but the real subject matter — grief, resentment, fear of growing up — stays grounded. One of those rare animated series that earns a second viewing once you know where it's going. Stream all seasons of Infinity Train (2019) online on iFILM.
