Train cars derail in Pittsburgh, no hazardous materials involved.

Five empty Norfolk Southern train cars derailed in Pittsburgh, marking the third derailment in two months for the company. No injuries or hazards have been reported. The Department of Justice has filed a lawsuit against the railroad company over the environmental damage caused by the derailment, and the state of Ohio has also filed a lawsuit to ensure Norfolk Southern pays for the cleanup and environmental damage. The company has pledged to pay for the cleanup and announced several voluntary safety upgrades.
