(AP) – Another Norfolk Southern train derailed Thursday, this time in Calhoun County, Alabama, around 6:45 a.m. local time in the Quad Cities area of White Planes. It is estimated that 30 cars derailed, but no one was hurt and there were no hazardous materials leaked, but there is no indication as to what caused the train cars to leave the track. The train cars were empty and crews quickly responded to clear the wreckage. This is the third Norfolk Southern train that has derailed since last month. One derailed on Saturday on its way to Birmingham, Alabama. A train derailed on Feb. 3 in East Palestine, Ohio, and that train was carrying hazardous materials which burned for days, forcing the evacuation of the surrounding community. The latest derailment came as a hearing was being held in the Senate where Norfolk Southern’s CEO Alan Shaw apologized for the derailment and offered millions of dollars to the Ohio community to help it recover from the wreck.
