You have been at this spot aka the conductors side way more often now and there was a lot of dust on this train

The only other type of dust that gets that thick is where the crop duster make the pass over the field. Ballast tends to have a layer of thin rock dust and if they moved it around working today it got spread out and dried and the passage of this train stirs it up. Quite the deadhead move on well cars is there a bunch of mixed Freight and once again the group of eight boxcars so you always wonder about cardboard and the BC rail boxcar was a nice touch. 25 ethanol tanks and a secondary batch of general freight will it rain wrapped up with at least 42 cars of ethanol. The dust helped make for an interesting shot but make sure you gently wipe down your camera gear
