Charles Evans Hughes, Louisville Company v. United States…
“ Indeed, the few ticket passengers sometimes riding in the private car of another carrier could probably be accommodated in other equipment that must be hauled anyhow, and the transporting carrier would receive more revenue if they rode in an ordinary Pullman car. Under these circumstances a carrier hauling the private car of another line can not be said to have hired its use, as it would have no interest in doing so and pays no rental therefor. Even if car hire should be provided on private cars, it would obviously be a mere subterfuge which could not change the legality of the practice. ”
