"Communities alongside rail lines had two more close calls this week as freight trains carrying hazardous materials derailed in Houston and Detroit.
For the communities where this week’s wrecks took place, the damage was less severe than symbolic: a reminder of the importance of rail-borne hazardous materials to every part of the economy just after the crash in East Palestine, Ohio.
Houston is the capital of the nation’s petroleum industry, part of a sprawling crescent of refineries, crackers, factories and liquefaction plants stretching from Baytown, Texas, to the Mississippi River industrial corridor in Louisiana — sometimes called Cancer Alley.
And Detroit — the once-and-future heartland of American automotive manufacturing — is now a rising hub of electric vehicle and battery manufacturing, a suite of high technologies whose exotic chemistries depend on hazardous materials."
