Sherman Minton,
Reed v. Pennsylvania Railroad Company…
“ But the interstate commerce in which respondent is engaged is interstate transportation. If 'any part' of petitioner's duties is in 'furtherance' of or substantially affects interstate commerce, it also is in 'furtherance' of or substantially affects interstate transportation. The test for coverage under the amendment is not whether the employee is engaged in transportation, but rather whether what he does in any way furthers or substantially affects transportation. ”
