Signal Signaling

Exploration Stage: Expedition
From: Conductor
Description: I was saddened when I realized that the map had changed. Because I could no longer locate the city. But in fact, this was my chance to get out of the city! Because the change in the location of the tracks meant that there was a possibility of a way out of the city. Okay, let's take a look at the signaling system.
Completed: You see those flashing lights on the signaling devices? Every once in a while, a signal comes on to indicate that the road is open. I figured that was the time to get out of town.
