The player enters the city on a railway car that reaches a dead-end station with a rotatable track. The player cannot leave because the track has not yet been rotated.

While heading to the switch to rotate the station track, a previous prisoner of Rhem reaches it first and leaves in the player’s railway car. The player must then wander the city in search of a second railway station.

Each of the quarters of the letter is located in a different area not shown on the map provided in the game’s package.
