Following the tracks, they don't see much out in the dark. Occasionally the tree line presses close, here or there they'll have to trudge up a hill and back down again. Overall, the journey is rather uneventful, until they hit something out in the dark.

It's a ramshackle building, stretched out over the tracks. Likely a station, or something close to it. They will notice that many of the ties that once went under the metal beams of the track have been pried away or... gnawed on? The station itself is dark, though the closer they approach, they will hear movement inside. The door is shut tight, with almost an excessive amount of locks. Might be a lot of work to get in that way. There's also some broken sidewalk leading away from the building... or they could test the tracks and see if they can get in that way.

Oddly, when they are close to the building, they can hear muffled movement beyond the door.
