Abstract: Disclosed is a coupler for a coupling arrangement for a rail wagon. The coupler comprising a body and a knuckle. The body has a head portion at one end for engaging with a knuckle and a butt portion at an opposing end for engaging with a yoke. The knuckle extends between a protruding portion that engages a complementary knuckle of a coupler for an adjoining rail wagon, and a tail extending along a longitudinal axis for coupling the knuckle with the head portion of the coupler. The head portion comprises an interior wall defining an interior cavity for engaging the tail of the knuckle. The coupler is configured such that in use loading induced in the coupler is transferred between the knuckle and the head portion along a substantially evenly distributed load path.
