A cushioning apparatus for a railway car employs a shortened yoke having a draft gear housing integral with the yoke. A stack elastomeric pads is provided in the housing, and a second stack of elastomeric pads and corresponding rigid metal plates, is positioned in the sill behind the modified yoke to absorb buff loads on the coupler. In embodiments, the entire assembly may be placed in a sill having forward stops, intermediate stops, and rear stops.

The invention relates to a coupling arrangement for a rail vehicle that includes a coupling rod which extends along a longitudinal axis, a bearing bracket to which the coupling rod is connected at a second axial end, a bearing between the bearing bracket and the coupling rod, and a support structure which elastically supports the coupling rod in relation to the movement in the vertical direction. The support structure is positioned in the vertical direction at least predominantly level with the bearing bracket and/or with the coupling rod in a manner substantially coaxial with respect to the longitudinal axis.

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.
