An interlocking type F railway car coupler recognized by the Association of American Railroads (A.A.R.) as alternate standard equipment and which is provided with a hood. The hood has a roof which overlies the knuckle-receiving recess of the F type coupler to afford vertical interlock between two opposed coupled car couplers when the F coupler is intercoupled with an automatic knuckle-type of car coupler known as an A.A.R. Standard E coupler.
