If there is any industry that has experience in rapidly putting the pieces back together after their property is trashed by nature, that is the one. Railroads can be obtuse as hell about a lot of things, but their track and structure employes are generally people who know what they are about.
The petrochemical industry is pretty good at recovery, although their problems generally aren't caused by nature. I'm figuring that they should be able to get plants back on line about as quickly after this as they do after an explosion. I think a lot of folks are going to be surprised on how quickly some of the refineries come back on line. The biggest delay at some won't be in the damage repair, but in assembling and housing workers.
