Hugo Black,
United States v. Capital Transit Company…
“ As previously noted, a Virginia worker could board its local bus or streetcar, ride to a District terminal of Transit's Virginia bound bus, board it, and obtain the benefit of a transfer supplied by Transit. So also could Transit's passenger get the benefit of a transfer on the return journey home from work. Had Transit not owned the separate vehicles used in the transportation, these arrangements would have constituted 'joint rates' for a 'through route' within the statutory meaning of the term. ”
