delivered the opinion of the court.
James Dunlavy was on July 19, 1912, employed by the Chicago, Burlington & Quincy Bailroad Company, the appellant, and the Chicago Bock Island & Pacific Bailway Company, as flagman at the crossing of the roads of those companies of a public street in the City of Moline, Bock Island county, Illinois, and while so employed was struck by a freight car that was being “shunted” or pushed by appellant’s servants on its track crossing that street, and received injuries from which he died. His widow, Winifred Dunlavy, the appellee, as administratrix of his estate, brought this action in the Circuit Court of Bock Island county to recover for his death. She filed a declaration, which as amended contained counts on common-law negligence and liability under the laws of this State, and counts charging liability under the Federal Employers’ Liability Act. Appellant pleaded the general issue and a jury was impaneled to try the cause. At the close of all the evidence appellant asked for a directed verdict in its favor, whereupon appellee dismissed all counts of the declaration drawn under the Federal act. Appellant renewed its motion for a directed verdict, which was denied, and there was a verdict and judgment thereon against appellant for $3,150, from which judgment this appeal is prose-*78outed, and a reversal is asked, mainly on the ground that the cause is comprehended within the meaning and scope of the Federal Employers’ Liability Act. If it is, then appellant’s liability is exclusively governed by the Federal statute, and no action can be maintained under our State law. This is held and the authorities so thoroughly reviewed in the late case of Staley v. Illinois Cent. R. Co., 268 Ill. 356, that we refer to the opinion of the court in that case without repeating what is there said. That part of the Federal act especially applicable to questions here arising is quoted on page 366 of that opinion. The question is, as said in New York Cent. & H. River R. Co. v. Carr, 238 U. S. 260, 9 N. C. C. A. 1 (35 Sup. Ct. Rep. 780): “Whether, at the time of the injury, the employee is engaged in interstate business, or in an act which is so directly and immediately connected with such business as substantially to form a part or a necessary incident thereof. * * * The scope of the statute is so broad that it covers a vast field about which there can be no discussion. But * * * the courts are constantly called upon to decide close questions where it is difficult to define the line which divides the State from the interstate business. * * * But the matter is not to be decided by considering the physical position of the employee at the time of the injury. If he is hurt in the course of his employment while going to a car to perform an interstate duty, or if he is injured while preparing an engine for an interstate trip, he is entitled to the benefits of the Federal act, although the accident occurred prior to the actual coupling of the engine to the interstate cars.” In that case an employee was injured while attempting to set a brake on an interstate car which had been cut out of the train and backed into a siding, but because it was necessary to set such brake in order that the engine to which the car was attached might, when uncoupled, return to the train and proceed on its interstate jour*79ney, he was held to be employed in interstate commerce at the time of his injury.
The street where appellee’s intestate was injured was crossed by the main track of the Bock Island road and the main track and several switch tracks of appellant’s road, the switch tracks used in part, if not entirely, to serve the Moline Plow Company’s factory located near by. There was an ordinance of the City of Moline requiring gates to be maintained at this crossing, and there had for some time been two gates about one hundred feet apart, one on the south of the Bock Island tracks, and one on the north of appellant’s tracks, maintained and operated to guard the crossing. Deceased had worked as a flagman for a year or more, and these gates being out of use, he had at the time of his injury been working about a month at that crossing. His duty was the usual one of a railway flagman at a street crossing. He was in the employ of both roads and guarding the street crossing, on approach of trains of either road. Appellant was then using two of its tracks at and near this street crossing in delivering two carloads of malleable iron which had been shipped from Milwaukee, Wisconsin to the Moline Plow Company; and to effect the delivery it was necessarily moving two empty cars from the premises of the Moline Plow Company to make place for them. It is claimed by appellant, and we think the evidence sustains its contention, that deceased was struck by one of the loaded cars; but it is claimed by appellee that the evidence, at least, leaves it in doubt, whether it was one of the loaded cars or one of the empty cars that struck him. However that may be, there is no question that he was injured in the operation of delivering two loaded cars that had been shipped from the State of Wisconsin, and whether he was injured while appellant was trying to make a place for that delivery by removing two empty cars that were in the way, or by the two loaded cars that *80were being pushed into the place after it was cleared, is not, in our opinion, very material. Deceased was at the time trying to stop a horse and vehicle that was . on the street crossing driving across the tracks, and while so doing was struck by the car that was being “shunted” across the street; which means that it was pushed across the street by placing a stake or bar between the head of the engine and the car and in that way setting the car in motion.
It is true that to come within the Federal statute the carrier must be engaged in interstate commerce and the injured servant be then employed by it in such commerce; but the servant could not so lie employed if its master was not engaged in interstate commerce, therefore to say that the servant at the time of his injury was employed in interstate commerce means that his master was also so engaged. It has been held that a servant is engaged in interstate commerce while repairing a switch on tracks used indiscriminately for both kinds of commerce, and that it is immaterial whether the train that struck him was engaged in that commerce or not. Central R. Co. of New Jersey v. Colasurdo, 113 C. C. A. 379,192 Fed. 901. A carpenter repairing a bridge over which both kinds of commerce are carried, if injured under such circumstances, cannot take his choice of remedy under the State and Federal law, for he is engaged in interstate commerce, and the national act is exclusive. Pedersen v. Delaware, L. & W. R. Co., 229 U. S. 146 [3 N. C. C. A. 779]. All section men and track laborers working on any part of the track or switches used by a common carrier by railroad, indiscriminately both in interstate and intrastate commerce, are employed in interstate commerce within the meaning of the Federal act. San Pedro, L. A. & S. L. R. Co. v. Davide, 127 C. C. A. 454, 210 Fed. 870; Central R. Co. of New Jersey v. Colasurdo, supra; Zikos v. Oregon R. & Nav. Co., 179 Fed. 893. A fireman on a locomotive engine repairing *81Ms engine for an interstate trip is, while so engaged, protected by the national act, although the engine had not been coupled to the cars of the train. North Carolina R. Co. v. Zachary, 232 U. S. 248 [9 N. C. C. A. 109]. Yard clerks in the employ of common carriers by railroad wMle inspecting and making a record of the seals on car doors, putting labels on cars to guide switcMng crews, etc., are employed in interstate commerce if trains upon which they are so working have any cars containing interstate commerce. St. Louis, S. F. & T. R. Co. v. Seale, 229 U. S. 156. It is not essential, where the negligence complained of was that of a coemployee, that he must also be employed in interstate commerce. Pedersen case, supra. We are of opinion that deceased was employed in interstate commerce at the time of Ms injury if appellant was then so engaged, and that in so holding, under the facts of tMs case, we are not in conflict with the holdings of the courts in Patry v. Chicago & W. I. R. Co., 265 Ill. 310; and in Illinois Cent. R. Co. v. Behrens, 233 U. S. 473 [10 N. C. C. A. 153], under the facts in those cases. It is true that it must appear that the railroad is operated as a common carrier. Atchison, T. & S. F. Ry. Co. v. Victoria, F. & W. R. Co., 234 U. S. 1. Appellee insists that there is no proof in the record that appellant was engaged in interstate commerce or was a common carrier at the time in question, and suggests that it may have been, so far as the record shows, a company engaged in switching cars, and not an interstate railroad or a railroad engaged in interstate business. We will not stop to inquire what might be the character of a corporation engaged only in switcMng interstate freight to its consignee. It is to be observed that the fact that appellant is an interstate railroad is one of general knowledge, but whether courts may take judicial notice of that fact is not free from doubt. But we think the record discloses sufficient facts to warrant a finding from the evidence that appellant is *82a railroad and a common carrier, and avoid the absurdity of letting the case go off on a presumption that it is a corporation engaged only in switching cars in the City of Moline. Appellee offered proof that appellant was a railroad, operated as such, that it had a main track and several side tracks, that the City of Moline had recognized it as a railroad and passed ordinances regulating its operation; and we take judicial notice of the act granting its charter, which was declared a Public Act (Laws of 1849, p. 96), and we think we may take notice of amendatory acts changing its name. We are inclined to give weight to slight proof, if necessary, to establish a fact of such general knowledge, and one that we must know could have been readily established had attention been called to it on the trial. We therefore conclude that appellee’s intestate was at the time of his injury employed in interstate commerce and that the liability of appellant is entirely fixed and governed by the Federal act.
It is urged by appellee that there is no issue in the case whether deceased was at the time of his injury engaged in interstate commerce. This contention is based on the theory that a defendant sued under the State law should in its plea or answer set up facts showing it was engaged in interstate commerce at the time in question. The consideration that the defendant would ordinarily know whether it was so engaged and the injured employee might not know, or have means of knowledge of that fact, gives much support to the contention that the defendant should, as a matter of fairness, be required to give notice by its pleadings of such a defense, and some courts have so held; but it is not now an open question. The court in St. Louis, S. F. & T. R. Co. v. Seale, 229 U. S. 156, held, and in Toledo, St. L. & W. R. Co. v. Slavin, 236 U. S. 454, reaffirmed, that a recovery cannot be had under a State law on pleadings counting only on that law when *83the evidence develops that the case is controlled by the Federal statute, on the ground that “the case pleaded was not proved and the case proved was not pleaded.” This answers many contentions of appellee that appellant is estopped to raise the question here. The appellant, as we have seen, asked and was refused a peremptory instruction. It also asked and was refused instructions that the Federal act only controlled, and it made the point on its motion for a new trial, which seems to be more than was required under the above cited authorities.
There is much discussion by appellee of two ordinances of the City of Moline which she pleaded and gave in evidence, one in regard to gates at the crossing, and the other as to “shunting” cars, each of which it is claimed appellant violated, and was thereby guilty of negligence that caused the injury. It is stated again and again in varying language, in the authorities before cited, that the Federal act supersedes all State laws on the subject and controls all cases that fall within its provisions. Section 4 of the Act provides that the “employee shall not be held to have assumed the risks of his employment in any case where the violation by such common carrier of any Statute enacted for the safety of employees contributed to the injury or death of such employee.” The court in Seaboard Air Line Ry. v. Horton, 233 U. S. 492 [8 N. C. C. A. 834], held that the phrase “any statute enacted for the safety of employees” meant Federal statutes and said: “It is not to be conceived that, in enacting a general law for establishing and enforcing the responsibility of common carriers by railroad to their employees in interstate commerce, Congress intended to permit the legislatures of the several States to determine the effect of contributory negligence and assumption of risk, by enacting statutes for the safety of employees, since this would in effect relegate to *84State control two of the essential factors that determine the responsibility of the employer.” This expression of the United States Supreme Court, which is the final authority on questions arising under the Federal act, must be taken as a guide in determining what force and effect State statutes and municipal ordinances have in determining questions of liability arising thereunder.
It is not claimed by appellee that any count of the declaration on which judgment was entered avers sufficient facts to sustain a judgment under the Federal statute, therefore the judgment must be reversed. We will not attempt to notice in detail other errors discussed in the briefs; they are not likely, if they are errors, to occur on another trial. We express no opinion on any issue of fact other than we have before stated. The cause is remanded for further proceedings not inconsistent with the vi,ews herein expressed.
Reversed and remanded.
