William R. Day,
Pennsylvania Railroad Company v…
“ It is in no just sense a regulation of commerce. It does not undertake to impose any tax upon the company, or to restrict the persons or things to be carried, or to regulate the rate of tolls, fares, or freight. Its whole object and effect are to make it more sure that railroad companies shall perform the duty, resting upon them by virtue of their employment as common carriers, to use the utmost care and diligence in the transportation of passengers and goods.'It is true that this language was used of a statute of Iowa enacting a rule of obligation for common carriers in that state. ”
