SEATTLE—Environmental crews worked Saturday to contain a sheen of oil that appeared in the Columbia River along the Washington-Oregon border after a Union Pacific train derailed and caught fire, but officials said there was no immediate indication of harm to wildlife.
Sixteen of the 96 tank cars on the train derailed Friday near Mosier, Oregon, about 70 miles east of Portland. Four burned, sending a thick plume of black smoke into the sky before firefighters were able to extinguish the flames a little after 2 a.m. Saturday.
No injuries were reported.
