ABSTRACT:
A liner for use in a draft sill to protect the sill from damage and wear caused by draft gear movement. The draft gear is attached to a coupling to transmit moving forces from the coupling to the car causing. The draft gear is isolated from the side walls of the draft sill by the liner to reduce wear on the draft sill as the draft gear absorbs and cushions impacts from the buff and drag events. These impacts may cause the followers, yoke and resilient members move toward the side walls and contact the liner disposed between the draft gear and the draft sill for protecting the side walls from damage and wear.
