Yeah basically. And it's completely arbitrary. In one episode we see the Train stole a lunch lady who knew one of the characters, possibly because she was mean to kids a few times. This mostly innocent woman with a shit job has to navigate surrreal Narnia puzzles, possibly for YEARS, because her job sucked and she maybe, maybe snapped at some kids once.
The Train is psychotic. Which for me is honestly part of the fun. It's arbitrary and stupid and insane, and its moral "objective" is warped and twisted by AIs and people pursuing their own purposes.
