ABSTRACT:
The present invention relates to a drawbar railway coupler connection. The drawbar contacts a follower block which in turn contacts a wedge shaped shim. Such shim provides an essentially slackless feature to the coupling connection. Further, surfaces of the follower block and the shim or of the shim and the rear cavity wall are modified such that alignment of the shim within the cavity is assured despite any angling or slight rotation of the drawbar.
