OOC:
This is pretty much the car you’re in, there’s a door between the area with the bathroom and galley and the compartment you’re in. The people you can hear and vaguely see are on the far side of that door. The sleeper car is one car in front of you. Thus, the bandits if they are bandits, are in the same car as you. Sorry I made a muddle of explaining it.
The train is kind of this.
Engine / Tender / Mail & Freight / 2nd Class / 2nd Class / Galley & Dining / 1st Class Sleeper / 1st Class Lounge.
The couches are slightly less regular, in their placement, more organic, the wall next to the door to the washrooms on both sides does not have seats against it.
