Abstract
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.
