The plaintiff in error (herein called the defendant) owns and operates approximately 18 miles of railroad track in the city of Fort Worth. Its business is confined to switching, classifying, and assembling ears witbin its yards, and switching the same from and to industries in Fort Worth to and from transfer tracks owned by railroad companies engaged in carrying both intrastate and interstate freight to and from such transfer tracks. Cars so switched or moved by defendant include such as contain both interstate and intrastate shipments. The defendant moved over its lines, from where it was placed on a transfer track by a railroad company, a car the coupling apparatus of which was so out of repair and inoperative that the ear could not be coupled or uncoupled without the necessity of a man or men going between the ends of that car and the one to which it was coupled. When that movement was made, neither that car nor any car with which it was then connected or moved contained any interstate shipment, either incoming or outgoing. Because of the above-mentioned movement of the car having the defective coupling apparatus, the defendant was adjudged liable for the penalty prescribed by the Safety Appliance Act, as amended by the Act of March 2, 1903, 27 Stat. 531, § 2, 32 Stat. 943, § 1, Comp. Stat. §§ 8606, 8613 (45 USCA §§ 2, 8).
By section 1 of the Act of March 2, 1903, the provisions of the Safety Appliance Act wore so extended as to apply to “all * * * ears * * used on any railroad engaged in interstate commerce.” As the defendant uses its tracks to haul over them interstate shipments to and from their destination, it cannot plausibly be questioned that the defendant’s lines constitute a “railroad engaged in interstate commerce.” In behalf of the defendant it was contended that the prescribed penalty was not incurred by the movement in question, because no interstate traffic was involved in that movement. This contention is not sustainable, as it has been settled by authoritative decisions that the penalty is incurred by moving on a railroad engaged in interstate commerce a car defectively equipped as the one in question, though at the time of such movement that car and others in connection with which it is moved are engaged exclusively in intrastate commerce. Southern Ry. Co. v. United States, 222 U. S. 20, 32 S. Ct. 2, 56 L. Ed. 72; Southern Ry. Co. v. Railroad Commission of Indiana, 236 U. S. 439, 35 S. Ct. 304, 59 L. Ed. 661.
The judgment is affirmed.
