Infinity Train Book 4 is about to pull into the station and the series dropped a look at the key art for this season. HBO Max and series creator Owen Dennis have announced that this will be the last batch of episodes of the beloved animated series. However, that hasn’t dimmed fans’ appetite for more of that spooky locomotive. This time, our protagonists are Min-Gi and Ryan, two childhood friends who had dreams of rockstar-dom. When they wake up on the train, they’ll have to learn the rules to return home, and learn a bit more about each other. The first trailer for Book 4 indicated that the two friends would be straining against the changes of adolescence. it will be interesting to see how those themes are addressed as the series continues on. People have loved Infinity Train so far, and although it isn’t the grand finale that Dennis had mapped out, the ride should still be satisfying.
