Abstract
A cushioning apparatus for a railway car employs a shortened yoke with a reduced-width tail for placement between stops in a conventional railway car sill. A first stack of rigid plates with elastomeric pads is provided between the straps of the modified yoke behind the coupler follower, and a second stack of plates and elastomeric pads 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, adapted to house a hydraulic cushioning unit.
