An automatic hook type railway car coupler having a spring biased coupling hook mounted in its head for horizontal pivotal movement and adapted for interlocking engagement with the hook of an opposed similar coupler when the couplers are in a coupled position, and inboard projections and pocket portions disposed on opposite sides of the longitudinal central axis of the coupler adapted to mate with complementary means on the opposed similar coupler for interlocking the couplers both vertically and horizontally when they are in a coupled position, More particularly, the coupling hook and inboard projections each have a forwardly extending tapered portion defining first nd second lateral alignment means, respectively, adapted to provide a more compact arrangement of guiding surfaces for improving the lateral gathering characteristics of two opposed misaligned couplers approaching each other during a coupling operation.
