Louis Brandeis, Galvestion Railway Company v. Woodbury…
“ Section 1 declares that the act applies to 'any common carrier * * * engaged in the transportation of passengers or property * * * from any place in the United States to an adjacent foreign country.' A carrier engaged in transportation by rail to an adjacent foreign country is, at least ordinarily, engaged in transportation also from that country to the United States. The test of the application of the act is not the direction of the movement, but the nature of the transportation as determined by the field of the carriers' operation. ”
