They could crash trains into a chemical plant, or release chemical or biological weapons on a train, there are a lot of possibilities, none pleasant.

Abu Khalil's expertise is chemical and biological weapons.

He ran the training site for that for Aq in Afghanistan -- see a couple of articles I posted a few posts back.

Are there very many chemical plants at the end of railroad tracks? I suppose there could be loading docks or whatever they call them in the train world...depots? Just wondering...
