According to a report released by the University of Washington in October 2015 and published in Atmospheric Pollution Research, pollution from coal trains is nearly double that of freight trains. Researchers led by Dr. Dan Jaffe used video cameras to identify train type and speed coinciding with emission spikes. According to the study, one in every 20 coal trains in the Columbia River Gorge is a “superduster” that releases large visible black plumes of coal dust from the uncovered coal cars.
