A 120-car train hauling Canadian crude oil derailed in western Pennsylvania Thursday.
Twenty-one cars left the tracks. Heavy crude spilled from four tank cars but didn’t ignite.
The train was operated by Norfolk Southern.
There were no reports of injuries.
NIneteen of the derailed cars carried crude.
Northern Southern said between 3,000 and 4,000 gallons of oil were spilled.
Two other derailed tank cars held liquefied petroleum gas.
The derailed cars crashed into an industrial building near the tracks by the Kiskiminetas River in Vandergrift.
There were two crude train derailments in January including another derailment in Pennsylvania.
Seven CSX cars – six of them carrying crude oil – derailed on a 128-year-old bridge over the busy Schuylkill Expressway in Philadephia. None of the tanker cars leaked or caught fire. And in northwestern New Brunswick (Canada) a train derailed and erupted in a fireball that forced the evacuation of about 60 people in the sparsely populated area.
In December, a crude train carrying volatile light Bakken crude derailed and exploded near Casselton, North Dakota. There were no injuries.
In November, a train hauling Bakken crude from North Dakota derailed and exploded in Alabama, spilling more than 700,000 gallons of oil from 26 tanker cars. No one was killed in that accident.
In July last year, a derailment and explosion in Lac-Megantic, Quebec killed 47 people and destroyed much of the town.
Authorities didn’t say if the heavy winter storm in Pennsylvania contributed to Thursday’s accident.
Railroads and oil companies have been working with the federal government to improve safety standards for hauling crude oil.
