A 120-car Norfolk Southern 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 at a bend by the Kiskiminetas River in the town of Vandergrift, according to town and company officials.
Nineteen of the derailed cars were carrying oil and two held liquefied petroleum gas, Norfolk Southern said. Three of the crude tank cars spilled after the incident, though the leaks have since been plugged. The company did not say how much oil spilled.
The train was heading from Conway to Morrisville, Pennsylvania. Some of the crude on board was destined for an asphalt plant in Paulsboro, New Jersey, owned by NuStar, a NuStar spokeswoman said.
The clean-up was underway on Thursday as a heavy winter storm gathered pace, leaving about four inches of snow on the ground by midday Thursday. An investigator from the Federal Railroad Administration was on route to the scene, the railroad regulator said.
"I heard a strange noise, a hollow, screeching sound," said Ray Cochran, who watched the train derail from his home on a hill above the tracks. "I looked out the window and saw three or four tankers turn over and one of them ran into the building."
The train crashed into a building owned by MSI Corporation in an industrial complex that backs onto the tracks. All employees had been accounted for, said Sandy Smythe, a public information officer with Westmoreland County's public safety department, which includes Vandergrift borough.
MSI declined to comment.
Thursday's accident is the latest in a spate of crude oil train derailments that has prompted calls for more stringent rules regulating crude by rail, shipments of which have soared in recent years as pipelines fail to keep up with growing supply.
It comes ahead of a Senate hearing concerning the safety of transporting crude by rail, which has become a major political issue as the incidents pile up. The hearing was scheduled for Thursday but was delayed by the snow.
Thursday's accident was the second in less than a month in Pennsylvania. A train hauling crude on a CSX Corp <CSX.N> railroad jumped the tracks and nearly toppled over a bridge in Philadelphia on Jan. 20. There were no injuries or fire in that incident.
A train carrying Bakken oil from North Dakota last July derailed and exploded in Lac-Megantic, Quebec, killing 47 people and decimating much of the small town.
U.S. and Canadian railroad companies, tank car owners and regulators are investigating ways to transport crude on the rails more safely. Much of the focus is on phasing out older tank cars, known as DOT-111s, that do not meet the latest safety standards.
DOT-111s built before 2011 are prone to puncture and fire during accidents, regulators say.
It is as yet unclear what type of cars were involved in Thursday's accident.
