Cushioning apparatus for a railway car

An end-of-car cushioning device for a railway car, comprising:

• a yoke having aligned apertures at a front end adapted to receive a pin or key for attaching the yoke to a railway car coupler, and having a vertical wall at a second end of the yoke opposite the front end;
• a coupler-receiving member adapted to receive buff force from the coupler and adapted to move inside the yoke;
• a first stack of elastomeric units positioned between the coupler-receiving member and the vertical wall of the yoke, each elastomeric unit in the first stack comprising a metal plate and at least one elastomeric pad, said first stack being compressed by draft and buff loads on the coupler;
• a front buff plate positioned adjacent to and rearward of the yoke and connected to a rear buff plate by a rod;
• a second stack of elastomeric units positioned between the front buff plate and the rear buff plate, each elastomeric unit in the second stack comprising a metal plate and at least one elastomeric pad, said second stack being compressed in response to buff loads on the coupler;
• wherein,
• the yoke, the front buff plate and the rear buff plate are positioned within a center sill of the railway car.
