When I worked in Charleston, West Virginia in 1988 as a salesman for Zee medical Serv. I rented an Apartment in Belle, WV that was fairly close to some huge coal train yards. I use to spend almost every sat. & sun. there w/my old 35mm camera. When I went home just before dark I was usually covered in Coal Dust. I could only get about 100 ft. from the local haulers which back then was close. I never realized how dirty that place was until I left.
Now, all of my coal on the layout is glued in. I use to leave it loose, but everytime I had a derailment most of it got dumped. I have plastic coal, real coal & water filter coal. Not much dust here. I kinda miss WV. I use to spend a lot of days servicing the coal mines in the hills when I worked there. Just before I left in Dec. of 88 I stood up on the overpass above the yards & took tons of linked pictures. Don't have them anymore though.
