It is well established by decisions of the Supreme Court of the United States that the right to regulate interstate commerce is exclusively vested in Congress, and that the States can not pass any laws directly regulating such commerce; but that the States may, in the exercise of their police power, pass laws in the interest of public safety which do not interfere directly with the operation of interstate commerce; that the constitutionality of a State statute regulating the operation of railroad trains depends upon its effect on interstate commerce; and that, in the absence of congressional regulation on the subject, a State may make reasonable regulations as to the manner in which trains shall approach, and give notice of their approach to, dangerous crossings, so long as they are not a direct burden upon interstate commerce. Southern Ry. Co. v. King, 217 U. S. 524 (30 Sup. Ct. 594, 54 L. ed. 863). No exact rule can be formulated by which to determine in advance what enactments along this line by States are valid and what are invalid. In Southern Ry. Co. v. Atlanta Sand Co., 135 Ga. 35 (68 S. E. 801), it was said (p. 46) : “x4s the Supreme Court of the United States have mentioned reasonableness as a guide in determining the extent to which a State law may affect interstate shipments without being invalid, and as reasonableness or unreasonableness is a matter for which no absolute standard can be pre*244scribed, but a thing sometimes appears reasonable to one mind, yet unreasonable to another, and even the same person may change his view as to what is reasonable with age, experience, and reflection, the determination of questions like that now before us involves no small difficulty.” We will cite only a few of the many cases in which State laws have been held valid though to some extent affecting interstate commerce. In Louisville & Nashville R. Co. v. Kentucky, 161 U. S. 677 (16 Sup. Ct. 714, 40 L. ed. 849), Mr. Justice Brown said (p. 702) : “It has never been supposed that the dominant power of Congress over interstate commerce took from the States the power of legislation with respect to the instruments of such commerce, so far as the legislation was within its ordinary police powers. Nearly all the railways in the country have been constructed under State authority, and it can not be supposed that they intended to abandon their power over them as soon as they were finished. The power to construct them involves necessarily the power to impose such regulations upon their operation as a sound regard for the interests of the public may seem to render desirable. In the division of authority with respect to interstate railwa3rs Congress reserves to itself the superior right to control their commerce and forbid interference therewith; while to the States remains the power to create and to regulate the instruments of such commerce, so far as necessary to the conservation of the public interests.” In that case a State statute of Kentucky prohibiting a railroad or other common carrier from consolidating or pooling its earnings with a parallel or competing line, and prohibiting certain other leases and combinations, was held valid. In Hennington v. State, 90 Ga. 396 (17 S. E. 1009), a statute of this State which made it a misdemeanor to run a freight-train on Sunday was upheld; and this was affirmed in Hennington v. Georgia, 163 U. S. 299 (16 Sup. Ct. 1086, 41 L. ed. 166). Seale v. State, 126 Ga. 644 (55 S. E. 472). In Atlantic Coast Line Railroad Co. v. State, 135 Ga. 545 (69 S. E. 725, 32 L. R. A. (N. S.) 20), a law of this State which required railroads to use headlights of a certain character was upheld; and this was affirmed in 234 U. S. 280 (34 Sup. Ct. 829, 58 L. ed. 1312). In Lake Shore &c. Ry. Co. v. Ohio, 173 U. S. 285 (19 Sup. Ct. 465, 43 L. ed. 702), a State law requiring three regular passenger-trains to stop each way daily at every village containing over 3,000 inhabitants was upheld. *245In Erb v. Morasch, 177 U. S. 584 (20 Sup. Ct. 819, 44 L. ed. 897), it was held that a regulation by the city of the speed at which railroad trains might run within its limits was valid, although applicable to interstate trains, at least until Congress had acted on the subject. We forbear undertaking to map'out “the twilight zone” in which State authorities may act until Congress has acted on the subject. See also Crutcher v. Kentucky, 141 U. S. 47 (11 Sup. Ct. 851, 35 L. ed. 649); Southern Railway v. Melton, 133 Ga. 277, 298 (65 S. E. 665), and cit.; Southern Railway Co. v. Atlanta Sand &c. Co., supra.

In Southern Railway Co. v. Grizzle, 131 Ga. 287 (62 S. E. 177), it was declared that the section of the State code now under consideration was not, with respect to a railroad company doing an interstate business, invalid as being a regulation of interstate commerce, but was a police regulation designed to secure public safety, and valid as such.

In Central Railroad Co. v. Hall, 109 Ga. 367 (34 S. E. 605), the actual ruling was that where the crossing was one half mile from the depot from which the train started, the law applied. In the opinion Mr. Chief Justice Simmons expressed some views as to the hardship or effect upon rapid transit which might arise from the law. What he said on this subject was an obiter dictum. He practically conceded the propriety of such a law before the days of rapid transit, as an exercise of the police power for the preservation of the public safety. It can hardly be claimed that rapid transit is more important than human life. It must also be borne in mind that while the commerce of the country calls for rapid transit, the local development and increase in population also create a greater necessity for public highways and for means for protecting the safety of those who use them.

In Southern Railway Co. v. King, supra, it was held that one who would strike down a statute as unconstitutional must show that it affects him injuriously and actually deprives him of a constitutional right. Mr. Justice Day said (pp. 536, 537), “They [referring to the averments of the plea] do not show the number or location of the crossings at which the railway company would be required to check the speed of its trains so as to interfere with their successful operation. Eor aught that appears as allegations of fact in this answer, the crossing at which this injury happened *246may have been so located and of such dangerous character as to 'make the slackening of trains at that point necessary to the safety of those using the public highway, and a statute making such requirement only a reasonable police regulation, and not an unlawful attempt to regulate or hinder interstate, commerce. In the absence of facts setting up a situation showing the unreasonable character of the statute as applied to the defendant under the circumstances, we think the amended answer set up no legal defense, and that the demurrer thereto was properly sustained.”

If the State legislature may regulate the speed of trains in approaching dangerous crossings and the signals to be given in so doing, necessarily it must be allowed some judgment in determining when such regulations should be made. It requires no argument to- prove that grade crossings are dangerous, especially in populous communities. In urging that, if the number of these crossings increase, the police power of the State terminates, there is danger of taking the anomalous position that as the danger to the public increases the State loses its authority to protect its citizens therefrom. Take, for instance, a populous city. The streets may cross the railroad at frequent intervals, and many people may pass over them. Surely this would rather furnish a reason for holding that the State has the power to protect the public in such places of danger than that its effort to do so would be invalid because it might require a railroad train coming from another State to slacken its speed at those places. In the present case the railroad company alleges that between Atlanta and the Savannah river (a distance of 123 miles) there are one hundred and twenty-four grade crossings. It is hardly within the raDge of possibility that they are distributed equally along the line. On the contrary it may fairly be assumed that many of these crossings are in populous sections, — at stations or in towns or cities along the route. It is not alleged how many of them are in the country or in sparsely settled districts. So that it may be that the very situation hypothetically stated above may actually exist in this case, and the railroad company may be complaining that at a place in a populous section there are frequent crossings, and that it ought not to be required by the State law to regard the safety of the public at such places, because of the very increase of danger at them. It does not appear that the operation or speed of trains in stretches ol *247country sparsely settled and with few crossings is seriously affected, or that the trains may not run for long distances without stoppage; or that slowing down from a high speed in populous places may not serve for several crossings, if such allegations would make a difference. Surely it could not be held that a railroad company has the right to run at an unrestricted speed, and without giving proper signals, through towns, villages, or densely populated communities because there may be frequent grade crossings at such places. Furthermore, crossings may be situated between two neighboring communities, or they may be at places of danger where to prohibit the State from restricting the speed and requiring the giving of signals would be to license rashness.

The public have a right to use the public highways. Railroads have no inherent right to pass over them, except by virtue of a franchise from the State. The State has the right, in the exercise of its police power, to pass laws to preserve the public safety. Laws must be general in their character, and can not well single out and specify one public crossing and omit another, if the condition is such as to make a police regulation for safety proper. The mere fact that on a particular day or series of days a great number of people may not pass over a particular crossing is not conclusive that it is not a place requiring protection to the public. On other days there may be reasons why a great number of people would pass over the same crossing. Who shall determine when the State shall exercise the unquestionable police power for the safety of the lives of its citizens ? Shall it be the legislature who represents the sovereignty of the State in making laws, or shall every law thus enacted be subject to the opinion of a jury? How far shall the legislative discretion in determining whether a particular protective law should be enacted be nullified, where it undoubtedly has some basis, and the entire matter be relegated as a mere question of fact to a jury in each case, with the possibility of differences in their findings ? Shall the law which requires the erection of blow-posts, the giving of signals, and the regulation of speed, for the protection of the public at the crossing of public highways at grade over railroads, be entirely in the air, and applicable to one public crossing and not.to another, or to the same crossing at some times and not at others, according as a jury may find in regard to it? Under our system issues of fact are for the jury; and if the validity *248of this law in each case becomes a question of fact, then it will be impossible to tell in advance what is the law applicable to crossings of public highways and railroads. Or shall it be determined by the opinion of a court in each case, with a like resulting uncertainty ?

In the present case it is alleged in general, terms that the 124 public-road crossings over the defendant’s line of road in this State are the usual and ordinary grade crossings, and that there is nothing in the conditions surrounding them which makes any one of them peculiarly dangerous, other than such danger as is incident to the crossing of a public highway by the railroad track at grade. We do not think that this is sufficient to show that the law is invalid. Applying the well-recognized rule that allegations are to be construed most strongly against the pleader, this does not negative the fact that all of these crossings are dangerous. It in effect concedes that they are all dangerous as grade crossings, but merely alleges in general terms that there 'is nothing to make any one of them peculiarly dangerous other than this fact. Nothing more is stated as to the particular crossing where the injury occurred, except that it is within about two miles of a city.

In the Civil Code (1910), § 2585, par. 5, which forms a part of the general law on the subject of incorporation of railroad companies and their powers, it is declared that, “whenever the track of any such road shall touch, intersect, or cross any road, highway, or street, it may be carried over or undpr, or cross at grade level or otherwise, as may be found most expedient for the public good.” This section was taken from the act of 1892, but a similar provision existed under the act of 1881. While the defendant company may be a foreign corporation, it must operate in Georgia by virtue of a Georgia franchise; and while the charter under which it, or some subordinate company under the franchise of which it may operate, may not have been granted under the general incorporation law, yet that law indicates a public policy by which railroad companies may avoid danger and delays at grade crossings by means of crossings above or below grade. The code section now under consideration does not apply where the crossing is not at grade. Barton v. Southern Railway Co., 132 Ga. 841 (64 S. E. 1079, 22 L. R. A. (N. S.) 915, 16 Ann. Cas. 1232). Tt is quite probable that in many instances grade crossings could be obviated alto*249gether. Has a railroad company the constitutional right to disregard laws for obviating delays and dangers, and nevertheless to declare that the legislature can not enact a law of the character now under consideration for the protection of the public where grade crossings exist, and when in the legislative opinion there is reasonable ground for such an enactment?

If the rule is that one who seeks to overthrow a police regulation enacted by a State for public safety must make out a clear case in order to accomplish that purpose, it seems to us that the railroad in this case has failed to do so. Congress has not undertaken to pass any law covering the subject involved in the code section now being considered. It is therefore not a case of a conflict of a State law and an act of Congress within the power of the latter to pass; but it is a question whether the legislative power of this State has been so arbitrarily used that it shall be declared that the power conferred by the constitution of the United States upon Congress to regulate commerce among the several States shall ex proprio vigore strike down the hands of the State when they stretch out to protect the public from'danger.

The police regulation of speed and signals at highway crossings over a railroad in the State is not a matter which is inherently and exclusively one for congressional control; otherwise, the decisions upholding some of these State regulations could not have been made. Congress has not assumed control over the subject. The law under consideration does not undertake directly to deal with interstate commerce. Whatever effect such law may have on interstate commerce is only incidental and indirect. It does not prohibit interstate commerce or in terms refer to it. It does not directly impose any burden on it. It merely provides for public safety at railroad crossings where the legislature'have determined that such provision was necessary; and if it causes trains to move somewhat more slowly at such places, as a means of safety to the public, how can it be declared that such a law is invalid ?

We recognize the ruling made in Southern Ry. Co. v. King, supra, and by no means intend to disregard what was there decided. But, if what we have said above is well founded, the ruling here made does not conflict with what is held in that case. When a State statute is on trial for its life, some presumption in its favor should be indulged, and it should not be declared void except in a clear *250case. We do not think that such a case has been made here as requires a declaration that the section of the State Code which is attacked is invalid relatively to the railroad company.

If we should declare this police law of the State unconstitutional or invalid, should it be held void in toto as to all railroads and all crossings within the State over which interstate trains or commerce may pass, without regard to the number of such crossings over the different railroads, and their situations, or dangerous character; or should the law be declared invalid only as to the Seaboard Air-Line Railway, leaving it to stand as to all other railroads, at least until further consideration; and if it should be declared invalid as to the Seaboard Air-Line Railway, should it be so declared as to all crossings of public highways over that road, whether in populous districts, or in towns or cities, or not, or only as to the particular crossing where the injury complained of in this case occurred? Moreover, the danger to the public is as great from an interstate train as from an intrastate train. If we should hold, relatively to interstate trains, that this law is invalid, or invalid as to certain railroads, or as to certain crossings, should we still hold that, relatively to intrastate trains and those carrying only intrastate commerce, the provision is legitimate and valid to safeguard the public ? In other words, is it a good law for some railroads, some trains, and some crossings, and an invalid law as to other railroads and other trains and other crossings, though the purpose of the law in all cases is to provide for the safety of the public ? It must be remembered that railroads are in the nature of public highways, and that other public roads are also public highways, and that the traveling public have the right to use these public highways which traverse the country, though they may cross the lines of railroads.

Of course, the facts well pleaded must be taken as true on demurrer, whether in fact they are correct or not. And we have so considered them in the preceding discussion. Mere conclusions are not admitted by a demurrer. '
