Comparison of Coal Dust Fouled Railroad Ballast Behavior

2009-6-29  Comparison of Coal Dust Fouled Railroad Ballast Behavior—Granite Vs. Limestone. Fouling refers to the condition of railroad ballast when voids in this unbound aggregate layer are filled with fine materials or fouling agents commonly in the form of ballast aggregate breakdown, outside contamination such as coal dust from coal trains, or from subgrade soil intrusion.

Coal Dust Sierra Club

2021-11-4  Coal dust causes deadly train derailments and fires, and decreases visibility for those driving vehicles near tracks. Coal dust clogs spaces in the rail ballast and turns into a solid, plastic-like substance when wet. This reduces the friction needed for safe rail operation, decreases track stability, and can lead to train derailments.
