Rob,
Another interesting thought. The definition you find on different railroad associated web sites states a unit train carries a single commodity. A company that would use multiple types of freight cars for different commodities, like a paper mil, would get the commodities from different locations. Maybe they could all meet up at a classification yard to form one train to the mill. Would that be a unit train between the classification yard and the mill?
A train hauling a military battalion from its home base to a training exercise would have all sorts of cars to move the personnel and equipment, but have just one waybill. Could it be a unit train since the "single commodity" is the battalion?
I’m stuck at home so yes, I'm bored. On the forum too much.
