Element 115 in Vorkuta?

[DEFCON 1]

Once you go up the stairs in the guard tower and go to the catapult if you look to the right there will be a train with lots of train carts attached to it some of them or tipped over and it look like something spilled out of them, it is black and has the same orange glow to it as element 115 does. Is this a hint to a Vorkuta zombie map? Maybe. Do you think it's 115 or just coal?

Probably just an allusion to zombies, doesn't necessarily mean anything.
