A large train of about 50 cars derailed in Ohio near the Pennsylvania state line. The train was carrying a freight from Madison, Ill., to Conway, Penn., according to the operator, Norfolk Southern. At the time, no information was released about what caused the derailment. Officials in the area issued an evacuation order which remained in place through Saturday morning for people within a mile of the scene. No injuries were reported. Reports say firefighters from three states (Pennsylvania, Ohio and West Virginia) responded due to the location of the derailment about 50 miles (82 km) northwest of Pittsburgh and about 20 miles (32 km) from West Virginia. The train was carrying chemicals like vinyl chloride, butyl acrylate, ethylhexyl acrylate and ethylene glycol and monobutyl ether which the Environmental Protection Agency (EPA) later determined had been released into the air, surface soil and surface waters.
