The group's journey to the Crystal Empire is almost over, with only one train ride away from finally arriving. But the train seems to be running late with no word from any of the employees on board. They set out to investigate and help everyone, and discover the train being attacked by a Frostorge.
- Good All Along: Frostorge is presented as the antagonist of the episode due to attacking the train and trapping the employees on it. It turns out though that it was just protecting its fellow Snocicle, since the train was unknowingly disturbing them.
- Poor Communication Kills: The whole reason Frostorge was attacking everyone and stopped the train was because it was unknowingly disturbing all the Snocicle in the trees that were preparing to evolve. Frostorge was just protecting its friends from harm and continue their natural migration cycle. Once Cadance and the others realize this, they are able to make a deal with Frostorge to stop the train once a year so the Snocicle can evolve undisturbed.
- Shout-Out: The train employees share names with characters from Thomas & Friends.
