"A 120-car Norfolk Southern Corp train carrying heavy Canadian crude oil derailed and spilled in western Pennsylvania on Thursday, adding to a string of recent accidents that have prompted calls for stronger safety standards."
"There were no reports of injury or fire after 21 tank cars came off the track and crashed into a nearby industrial building at a bend by the Kiskiminetas River in the town of Vandergrift.
Nineteen of the derailed cars were carrying oil, four of which spilled between 3,000 and 4,000 gallons of oil, Norfolk Southern said. The leaks have since been plugged. The two other derailed tank cars held liquefied petroleum gas."
