Note the secrecy here, from both the Union Pacific and the Federal Railroad Administration (more a servant of than a regulator of the industry).
In the course of fighting a proposal for an LNG terminal in New Jersey, we learned a lot about the hazards of LNG. Unit trains of this would make crude oil look benevolent by comparison.
The Union Pacific provides these maps of its system in Minnesota and Wisconsin.
Could this be a foot-in-the-door for trains even more dangerous than the oil (bomb) trains?
