Western coals, now being shipped by unit trains to eastern and southern markets, contain from 13% to 32% moisture. Drying of these coals at the mine would reduce the cost of coal to the utilities from 10% to 16% IF the railroads do not materially increase rates on higher BTU coal.
The spontaneous combustion of dry coal can be inhibited, and the savings per unit train should range from $1,375,000 to $4,129,000 per year according to the various minimum tonnage rates. The shipment of dried coal will reduce the tonnages being shipped by 15%, or increase the railroad carrying capacity by approximately 20%, without additional expense to the railroads.
