Another Hoax

Exploration Stage: Compartment No. 8
From: Conductor
Description: I’d never inspect this train on my own. It’s good that you were also interested in the secret of the Foggy Express... Curses, in which compartment does this creepy music play? It gives me goosebumps. Let’s try to find a travel gramophone, it’s probably somewhere nearby!
Completed: I’m so grateful that you found the travel gramophone. Quick, turn this creepy music off! How’s this possible? There’s no record in the gramophone and yet it plays... the fog? It seems that the train is fooling everyone who enters it.
