Coal train dust mitigation - GIF

[Frank S]

BUT... did you level off the top of your coal, then emboss your company logo on the top of it, so people in airplanes flying over would be able to see where the coal came from?? (there is supposed to be some humor in there)

There are a lot of coal mines in China. Flattening the top of the load with the roller just makes spraying the dust mitigation substance more effective and efficient.Adding the company logo to the roller is a way to identify where the load originated. I doubt they had any other thoughts of how it might be taken as strange to those of us too lazy or too cheap to do the same with our coal trains
