A yoke for a railway car is provided with a coupler support protruding from a top wall of the yoke into an interior space in the yoke to contact the coupler shank when the coupler head is deflected downward to prevent the coupler from drooping after prolonged use.

A yoke assembly includes an outer housing having opposite front and rear ends and can define an interior chamber between the front end and the rear end. The yoke assembly also can include a guiding sliding bushing disposed in the interior chamber of the outer housing, a guide rod extending through the interior chamber of the outer housing and through the guiding sliding bushing, a bumper assembly coupled with one end of the guide rod, and an elastomeric body and/or a resilient body disposed within the outer housing between the guiding sliding bushing and the rear end of the outer housing. The bumper assembly can be positioned to be engaged by a mechanical head of a first coupler system of a first vehicle to position a first hook of the first coupler system for coupling with a second hook of a second coupler system of a second vehicle.

A spacer arrangement (300) is configured to be fitted into a mounting compartment of a rail vehicle in order to bridge a gap distance between an innermost portion of a draft gear (200) and at least one support surface of the mounting compartment. The spacer arrangement (300) has two opposing side members (312; 313) configured to transfer buff forces exerted on the draft gear (200) to the at least one support surface of the mounting compartment. The spacer arrangement (300) is configured to contact a respective side wall of the mounting compartment, each of which side wall is perpendicular to the at least one support surface of the mounting compartment. The spacer arrangement (300) contains at least one pressure device (302) positioned between the two opposing side members (312; 313), which at least one pressure device (302) applies a pretension force between the two opposing side members (312; 313) to reduce the risk that these members buckle in case of an extreme buff force on the draft gear (200).
