Long enough for the forest to forget man's claim on the bones of it's kin.

That's a DODX heavy duty military flatcar with three axle trucks suitable for tanks or ther heavy dense loads. Why it is out in the weeds is unknown. Where's the siding go to? It can't be too far off an active line.

That foliage growing on top suggests it's been there for 10 years or more.

There are several sidings, most of which went to a huge cement plant. Maybe I'll post some photos of the plant, too, though I wasn't feeling up to sneaking around the grounds (I spotted a hole in the fence - but I also spotted security guards going on-shift). The plant itself was declining until supposedly 6 months back when it shut down altogether, but it's been a while since the spur was in use - there's a lot of area which looks like it must've had railroad access at one time and which got converted to a place for trucks.
