There are bottles and cans laying around the interior, some tied to fishing line like a half-assed alarm system.

You climb over a makeshift wooden barricade and lower your feet onto the interior floor, easily avoiding the fishing line.

There’s no way you’re going to stand over those dark little burrows, so for now you’re standing on a crusty sheet of particle board laying on the ground right in front of the doorway. There’s not much of a floor to the caboose, and the ground itself is pocked with rocks, trash, and hard-packed dust.

But what almost makes you jump backwards is the sound of beeping… the heck is that? Morse code?

These four lights on the wall even start to flicker on and off with the beeping code. It seems like a pretty brief message and while you try to decipher it, you look down again and notice a mist that’s been slowly rising up from the dozens of small burrows.

Oh. Those aren’t burrows, are they? The white mist reminds you of what dry ice does on a hot day, just dissipating into desert air like it never even existed. However, your nose and throat start to tingle and you start to feel like you can’t breathe.

You get out of the caboose much faster than you entered and clear the area while your head swims. Maybe the ghostly apparition was trying to tell you something?
