OPB broke this story today, yuk! Most of this rail traffic is on the Oregon side of the Columbia River, transported on the Union Pacific rail line. If this oil spills it will sink, making clean up next to impossible.The photograph shows the tar sands oil pipeline spill that burst and ruined the Kalamazoo River. If a big spill happens in the Columbia River, with trains running next to the river, our beautiful salmon/sturgeon runs will be at risk.
