Officials now say more than 2,000 gallons of crude oil spilled during that train derailment Thursday morning in Westmoreland County. KQW had originally reported that there had been no spill.
The petroleum, though, covered the parking lot of a factory, and did not seep into the ground nor enter any nearby waterways.
Accident investigators say there were no injuries, but about 35 people were evacuated from the factory after two train cars struck their building.
The incident happened near Vandergrift during a heavy snowfall shortly before 8:00 AM on Thursday. A spokesman for the Westmoreland County Department of Public Safety says 21 cars of a Norfolk Southern train left the tracks, nineteen of which were carrying crude oil. An investigation continues into the cause of the derailment.
