to explain the train yard thing. during the winter trains get covered in ice, each car may get thousands of pounds of ice on it. multiply that by hundreds of cars and you have a train that has trouble moving freight and is dangerously top heavy. there are places like that all through the north. they use the giant furnaces to melt the ice quickly and efficiently.
barbed wire is used to keep people out. (some states have laws that say barbed wire may not face out)
just another paranoid vid. i saw one about aliens that was pretty convincing too.
