“ Upon the principles decided in these cases, a state railroad commission has the right, under a state statute, so far as railroads are concerned, to compel a company to stop its trains under the circumstances already referred to, and it may order the stoppage of such trains if the company does not otherwise furnish proper and adequate accommodation to a particular locality, and in such cases the order may embrace a through interstate train actually running, and compel it to stop at a locality named. ”

“ Under these statutes the commission has power (a) to stop, in its discretion, all passenger trains at all county seats at which the company has a depot; (b) to stop such of the passenger and freight trains at any depot as the business and public convenience may require. The order in question was made with regard to a place which is both a county seat and also one where the railroad has a depot. It is not plain under which section the commission acted. Its order simply states that the petition of the citizens of Magnolia is granted as to trains 1 and 3, and denied as to train 4. ”

“ A statute relating to railroad companies which provided that a company should cause three of its trains each way, if so many were run daily, Sundays excepted, to stop at a station containing over 3,000 inhabitants, was valid in the absence of legislation by Congress on the subject; and also a state statute which required all regular passenger trains to stop at county seats was invalid when applied to an interstate train, intended only for through passengers from St. ”

“ The complainant in this case, by a proper pleading, set up not only the diversity of citizenship, but also a constitutional question, and the complainant had the right to appeal from the judgment of the circuit court to the circuit court of appeals, and from its decision in such a case an appeal or writ of error may be taken to this court. ”
