Looks like people in Richmond are thinking along the same lines as I was

Horribly titled Herald-Leader article: Depot’s weapons center of new furor

On Jan. 6, a train crash sent a poisonous cloud of chlorine into the sky over Graniteville, S.C. It took 21/2 hours for the first warning to be issued. Nine people died.

Some of the world’s most lethal chemical weapons are stored in earth-covered bunkers at the Blue Grass Army Depot near Richmond, protected from terrorists and monitored for leaks by the Army.

What would happen if those chemicals were loaded onto train cars or trucks and a similar crash occurred in Louisville or St. Louis? Exposure to a tiny amount of VX, one of the chemicals stored at the depot, can kill a person within minutes. No one knows how many people might die in such a situation.
