All coal is not the same. It has different thermal values, different
chemical components, different amounts of ash, etc. Metallurgical coal
(for smelting) is not the same as steamer coal (for power plants).
When I toured the N&W export yards in Norfolk about 17 years ago, I was
surprised to learn all this. Coal from many different sources was being
"warehoused" in their yard. This was blended as it was loaded onto ships
to the buyers' specifications. The properties of every car of coal
received were held in their computers, and specific cuts of cars were
pulled for blending as needed.
This might well explain why the N&W would be receiving coal from other
sources. Perhaps a customer needed a blend that included some
Pennsylvania anthracite, for example, or a particular coal with some
other special property that was not mined on the N&W.
