Well, the USA has a huge freight railway network, and a lot of it is pretty rough. Derailments are common, as are loads of hazardous materials. This one was only yesterday:
About 28 train cars derailed Saturday afternoon along a rail line in Albert Lea, Minn., with cleanup efforts continuing Sunday.
A Union Pacific Railroad spokesperson Saturday that said the train “was carrying mixed commodities; however, we have confirmed two of the derailed cars are leaking hydrochloric acid. Union Pacific is working with emergency responders to determine a response plan.”
After initially issuing a shelter-in-place order for nearby residents as the scene was assessed, authorities later said there was no danger to the public. There were no injuries.
