"I don't think so." Peter says after a moment of thought. "The engine on the platform on day one was definitely a steam engine which typically runs on coal-I mean I really doubt that's what they're using for this train because a regular coal train could never travel in space and I really, really doubt it could travel in the void between universes. Uh... if that's... the void we're traveling in."

He rubs his forehead and leans back in the seat he's claimed to just lounge in. "You know, I don't mind traveling but I could really use more things to do on this train."
