“It is insisted that the court had no power in a proceeding of this character to fix the percentage of cars the relator should have, and to command that such percentage of cars should be furnished to the relator. The acts of Congress forbade discrimination and made it unlawful to give any undue or unreasonable preference or advantage to particular persons, companies, corporations, or localities, or any particular description of traffic, or to subject them to any undue or unreasonable prejudice or disadvantage in any respect whatsoever, and vested jurisdiction in the circuit and district courts to proceed by mandamus as a cumulative remedy for violations of the statutory provisions. We are unable to accept the view that Congress intended to confine the scope of the writ to admonition merely, or to a general command to desist from discrimination, rather than from the particular action in which the discrimination consisted. By the findings, the delivery to the relator of any less than 31 percent of the supply amounted to unlawful discrimination, and the judgment of the court did no more than to correct it.” Sometimes it is the denial of a switch, that blocks the independent; for example, the railroads controlled by the coal pool refused to put in a switch for the Johnson coal mine or to permit the company to put one in until suit to forfeit its charter for refusing equal opportunities to shippers was begun in the Ohio Supreme Court. Then the switch was put in. The Coal Combine and its railroads have persistently pursued the policy of crushing smaller rivals by denying them transportation facilities.
