“ The coal was loaded on cars to be transported to various points of destination not only in Pennsylvania, but in other states. The transportation to other states absolutely depended upon a proper supply of cars, and it is manifest that unjust discrimination against the plaintiff in car distribution would improperly obstruct the freedom of such transportation, in which the plaintiff had a direct interest. And the question presented is whether unjust discrimination of this character is a subject which falls without the scope of the jurisdiction conferred upon the Interstate Commerce Commission ”
